Keto Eggnog Pie

This keto eggnog pie starts with my buttery, flaky low-carb crust and gets filled with a real spiced eggnog custard, no gelatin, just pudding and whipped cream that sets overnight into something that actually slices clean. Only 4 net carbs per slice.

I've had sugar-free eggnog on my site for years now, but somehow I never turned it into a pie. Which feels like something past-me would side-eye current-me for. Every holiday I make it my personal mission to show up with a dessert that makes my family say, "Ohhh, you brought that one." One year it's banana cream, another year it's pecan, and this year I wanted something that felt classic, nostalgic, and just a little extra. Enter eggnog, but in pie form and only 4 net carbs per slice.

A bite taken from a slice of keto eggnog pie on a plate with whipped cream and nutmeg scattered around.

This one starts with my buttery, flaky keto pie crust, the same one you all already know and bake on repeat, and then it gets filled with the creamiest homemade eggnog custard that actually gets cooked like real custard should. It's gently spiced, folded into fluffy whipped cream, and chilled until it slices like something you'd proudly set in the center of the dessert table. If you've made my coconut cream pie or pumpkin pie, you already know how I build these fillings. Same approach, completely different flavor.

What makes this pie different from the others

  • No gelatin: I tested a gelatin version early on and the texture went rubbery, almost bouncy, which is the opposite of what custard should feel like. Beef gelatin also leaves a faint off-flavor that has no business being in an eggnog filling. The pudding and whipped cream method holds its shape without any of that weirdness.
  • Real eggnog base: This filling is built on a true eggnog base using egg yolk, milk, sugar-free sweetener and cream, then thickened with pudding and lightened with whipped cream so it holds its shape without feeling heavy. The flavor is rich and layered, not just sweet with a hint of nutmeg pretending to be eggnog.

If you're keeping things low carb during the holidays without wanting to skip dessert, this is the one. I tested the filling probably six times trying to nail that custard texture without it going too soft or too dense. It's festive, make-ahead friendly, and the kind of dessert that quietly disappears one slice at a time while everyone pretends they're "just having a small piece." If you're looking for more holiday baking ideas, my yule log and spice cake with cream cheese frosting are both favorites at my house too.

A no-bake filling that actually sets

Once the crust comes out of the oven, that’s it for baking. The filling never touches heat again after the stovetop. I cook the eggnog base, fold it into whipped cream, and let it set in the refrigerator. No worrying about overbaking, cracking, or timing it around everything else in the oven. I fill it, cover it, and let the fridge do the work. During the holidays when my oven is running nonstop with Christmas cookies and other desserts, that matters more than you’d think.

Make-ahead and storage

Make ahead instructions

I actually prefer making this the day before serving. The filling firms up overnight and the flavors layer together in a way they don’t on day one. Once it’s filled and set, cover tightly and store in the refrigerator for up to 3 days. Keep the whipped topping in a separate airtight container and add it right before serving for the fluffiest texture. During the holidays, this is how I stay ahead of the chaos.

Freezer instructions

I can freeze this, but the texture is best when it’s simply chilled. If you do freeze it, wrap the pie tightly in plastic wrap and then foil, and freeze for up to 1 month. Thaw overnight in the refrigerator and re-whip the topping if needed to bring back that light, airy texture.

Keto Pie Crust Ingredients

Keto Eggnog Filling Ingredients

Step by Step Instructions

  1. Make keto pie crust

    Add almond flour, coconut flour, xanthan gum and salt to a food processor. Give a quick pulse to combine. Add in chilled cubed butter and cream cheese. Pulse until coarse crumbles form. Add egg and vinegar. Pulse until combined and a dough ball forms. Flatten the dough into a circle disc in between two sheets of parchment paper and refrigerate for 30 minutes.

    For this step

    • 1 cup almond flour
    • 3 tablespoons coconut flour
    • 1 teaspoon xanthan gum
    • 1/2 teaspoon salt
    • 1/2 cup unsalted butter, chilled & cubed
    • 1 ounce cream cheese, softened
    • 1 egg
    • 1 ½ teaspoons white vinegar or rice vinegar or apple cider vinegar
    Keto pie crust dough blended in a food processor until a smooth, crumbly dough forms.
  2. Roll out dough

    Keeping the dough sandwiched between the parchment paper, roll out the dough using a rolling pin. Start from the center of the disc and work your way out in all directions. Continue rolling until you are at least an inch wider on all edges than the pie pan you want to use. Crust should be between 1/8 to 1/4 inch thick. Remove the top layer of parchment paper. Place pie pan upside down over pie crust. Hold one hand on the pie pan. Slide your hand under the bottom parchment paper and flip so the pie pan is on the bottom and crust is on the top. Remove the parchment paper.

    Pie dough rolled flat between two sheets of parchment paper with a rolling pin.
  3. Flute edges & blind bake pie crust

    Gently press the pie dough into the pie plate. Flute the ends of the crust. Prick the bottom of the crust all over with a fork to keep the pie from puffing up on the bottom as it bakes. Bake at 350 °F for 12-15 minutes or until the edges turn golden brown. If using pie weights, remove the parchment paper and weights for the last 3-5 minutes so the bottom bakes.

  4. Make sugar-free eggnog

    While the pie crust is baking, make the keto eggnog. In a saucepan, heat ½ cup of milk until warmed. While milk is warming, mix together egg yolk and 3 tablespoons powdered sweetener in a small bowl until it is thick and pale yellow.

    For this step

    • 1/2 cup milk of choice
    • 1 egg yolk
    • 3 tablespoons powdered sugar-free sweetener
    A bowl of ingredients for the eggnog filling with sweetener added to melted butter.
  5. Make sugar-free eggnog: temper the egg yolk

    Mix ¼ cup of the warmed nut milk into the yolk mixture. Then add the yolk mixture into the saucepan with the remaining warmed nut milk. Stir to combine. Continue cooking over low heat until the mixture has thickened and reaches a temperature of about 165 °F and will coat the back of a spoon. Remove from heat and stir in remaining nut milk and 1 tablespoon heavy cream. Place into the refrigerator to cool until ready to use.

    For this step

    • 1/2 cup milk of choice
    • 1 tablespoons heavy cream
    The eggnog mixture whisked until smooth and fully combined.
  6. Combine pudding

    In large bowl, whisk together the sugar-free eggnog, nutmeg, and pudding mix until the mixture starts to thicken (about 2 minutes).

    For this step

    • sugar-free eggnog
    • 1/2 teaspoon ground nutmeg
    • 1 box sugar-free vanilla pudding
    Eggnog pudding mixture being mixed with a hand mixer until thick and creamy.
  7. Make cream cheese whipped cream

    In another large bowl, combine the cream cheese, remaining powdered sugar, and bourbon. Mix using an electric mixer on medium speed until smooth. Add the remaining heavy cream, increase the speed to medium high, and beat until stiff peaks form.

    For this step

    • 4 oz cream cheese, softened to room temperature & cubed
    • 1/3 cup powdered sugar-free sweetener
    • 2 tablespoons bourbon or spiced rum
    • 2 cup heavy cream
    Heavy cream whipped with a hand mixer until stiff peaks form.
  8. Finish eggnog filling

    Scoop 1 cup of the whipped cream mixture into the eggnog pudding and gently fold with a rubber spatula until combined. Add 1 cup more of the whipped cream mixture and fold until combined.

    Whipped cream gently folded into the eggnog filling with a spatula until smooth.
  9. Fill the pie & chill overnight

    Spoon the eggnog filling into the baked, cooled pie crust and smooth the top. Cover, and refrigerate for 12 hours or overnight. Transfer the remaining whipped cream to an airtight container and refrigerate until ready to serve.

    Eggnog filling spread evenly into the prepared keto pie crust.
  10. Top with whipped cream mixture

    When ready to serve, if whipped cream mixture has flattened a bit, beat it with an electric mixer to get some of the air back into the cream. Top the pie with the whipped cream and dust with nutmeg.

    The finished keto eggnog pie topped with a smooth layer of whipped cream ready for garnish.

Frequently Asked Questions

Can I make this pie dairy-free?

I haven't tested a fully dairy-free version of this specific filling, but I'd swap the heavy cream for full-fat coconut cream and use coconut milk in place of nut milk. The cream cheese in the whipped layer could go to vegan cream cheese. I've done similar swaps in other pies and they work, but the texture will be slightly different, a little lighter and less rich.

Can I use store-bought eggnog instead of making it from scratch?

I wouldn't. Most store-bought eggnog has 15-20g of carbs per half cup, which would blow the macros on the entire pie. Making the eggnog base from scratch takes about 10 minutes on the stovetop and keeps this at only 4 net carbs per slice. I've been making my own for years and it genuinely takes less time than a grocery store run.

What's the difference between a baked and no-bake version?

I went with a no-bake filling on purpose. Most baked versions set the custard in the oven like a pumpkin pie, which gives you a denser, firmer texture. My method cooks the eggnog base on the stovetop, thickens it with pudding, and folds it into whipped cream. You get a lighter, creamier filling and there's zero risk of cracking or overbaking.

What sweetener works best to avoid a grainy filling?

I use powdered sweetener, not granular. Granular sweetener doesn't dissolve fully in a cold-set filling and you'll feel the grit in every bite. I use a powdered allulose or erythritol blend and it dissolves completely during the stovetop cooking step. If all you have is granular, pulse it in a blender or spice grinder for about 30 seconds until it's fine like powdered sugar.

Why is vinegar added to the keto pie crust?

I add vinegar to keep the crust tender and flaky. It slows down any gluten-like structure from forming in the dough, which is what makes almond flour crusts get tough or crack when you try to roll them. You won't taste it after baking. I've made this crust with and without the vinegar, and the difference in how it rolls and how it flakes is night and day. One of my readers even mentioned his crust held up and stayed crisp under the custard filling for two full days, which is something most pie crusts can't do.

Can I use any brand of sugar-free pudding?

I use Simply Desserts because it has better ingredients and is sweetened with stevia and erythritol, but Jell-O sugar-free works if that's what you can find. I've tested both and the set is nearly identical. The flavor is slightly more natural with Simply Desserts, but not enough that I'd tell you to order it online if Jell-O is already in your pantry.

Do I have to use alcohol in the filling?

I've made this both ways. The bourbon or spiced rum adds that classic eggnog warmth, but the filling still tastes like eggnog without it. If you want the flavor without the alcohol, I'd go with a teaspoon of rum extract. I've also tried vanilla extract as a substitute and it works, just less eggnog-specific.

Can I make this nut-free?

The filling is already nut-free if you use a seed milk like sunflower or hemp. For the crust, I've swapped almond flour for sunflower seed flour in other keto recipes and it works. The texture is slightly more crumbly, but it bakes and holds together. My pie crust recipe has more detail on flour swaps if you want to experiment.

Made this over the weekend and gave it the full overnight in the fridge, but the middle still slumped when I cut into it. Outer slices came out clean, so I feel like I’m close. Was my custard just not cooked down far enough on the stove, or is that a whipped cream folding problem? Want to get this one right next time.

Four net carbs and my husband had no idea it was low carb. I’ll be making it again at Christmas. ❤️

Set it up Thursday night and cut it Friday after dinner. Got clean slices, no weeping, and the nutmeg on top was just right.

The nutmeg on top is my favorite part of this pie. I’m so glad you gave it the extra day in the fridge.

Let the filling chill uncovered the first hour before you wrap it. Cover too soon and condensation pools on top, you get a slick wet layer, and it changes how the surface looks when you cut it.nnThe pudding-and-whipped-cream method comes out lighter than the cream-cheese-heavy custards most keto pie recipes use. And the eggnog flavor actually tastes like eggnog, not just spiced vanilla. Four stars because the spice depth fades between day one and day two, so it’s really at its best the night it finishes setting.nnThe blind-baked crust holds up against the wet filling better than almost any almond-flour crust I’ve tried. I think it’s the coconut flour. Pulls moisture differently than a pure almond flour base, so the bottom stays firm. Soggy bottoms have been your issue? Worth trying.

This is now my favorite keto dessert. I’ve made it about 20 times, and it’s always delicious. The crust is a little tricky, but the key is to keep it cold. I get a lot of compliments. Thank you.

Annie Lampella

Twenty times! You cracked the crust on your own, cold is the whole thing (I freeze my butter a full 30 minutes before it hits the food processor). You’re very welcome, Tony.

Don’t add extra flour when you roll the crust out between the parchment. Almond flour absorbs differently and dusting just throws the ratio off, the crust crumbled at the rim the one time I went off-script. Six batches in, parchment-only from here on.

Reply

Annie Lampella

I quit dusting for exactly that reason. Parchment only here too.

Reply

Kim P.

Does it have to set overnight, or can I get away with a few hours?

Reply

Annie Lampella

Hi Kim, you can get away with about 6 hours in a pinch, but the slices won’t hold their edges the way they do after a full night. The filling sets from the pudding and the whipped cream, not gelatin, so it firms up slowly and keeps firming right through hour 10 or 12. I cut into one at the 4 hour mark once and it was more of a spoon-it-into-a-bowl situation than a clean slice. Still tasted great. If you need it same day, I’d make it first thing in the morning and serve it after dinner.

Making two of these for a graduation party this weekend, can’t wait to see people’s faces when they find out it’s keto. Quick question on the xanthan gum in the crust: does it scale 1:1 or do you dial it back? In my experience it gets gummy fast when doubled.

Reply

Annie Lampella

You’re right to dial it back. I use 1 1/2 teaspoons and it still rolls out between the parchment without cracking. With too much vinegar the dough gets tacky and fights you.

Reply

Tony

custard smells perfect, just wish there was a heads up about the vinegar

Reply

Annie Lampella

Yeah. That raw dough smell can catch you off guard. I add it so the crust doesn’t crack when you roll it out. Bakes off completely though.

Reply

Lakshmi C.

Third batch in and I’ve learned not to rush the overnight chill. Cut into it at four hours the first time and the custard was soft enough that it just sort of spread on the plate. Let it go a full night and it holds and slices the way it should. Also been adding an extra shake of nutmeg on top right before it goes in the fridge. Really comes through on the surface in a way the spice in the filling alone doesn’t. Four stars from me because the crust edges crack on me sometimes, but the filling has come out right every single time.

Reply

Annie Lampella

Surface nutmeg stays sharp in a way baked spice doesn’t, so that tracks. For the cracking edges, I press the rim noticeably thicker than the base when I form it. Thin spots crack every time.

Reply

Lakshmi C.

Thicker at the rim, yeah. I think I was going too thin trying to get even coverage. Worth a shot.

4 net carbs per slice and it looks like the real thing. That reaction never gets old.

The crust-to-filling ratio is almost perfect, but I kept hitting the outer edge and getting plain almond flour with no spice. Fixed it by throwing a quarter teaspoon of nutmeg straight into the food processor with the flours. Now the eggnog flavor carries all the way to the last bite. Fair warning though: I pushed it to half a teaspoon on the second batch and it went from warm and spiced to borderline medicinal. Also, a full 24 hours in the fridge instead of just overnight made a real difference. Slices set firmer and held clean edges at room temperature longer than I expected.

Reply

Annie Lampella

Mixing it straight into the crust flour is the smarter fix. Quarter teaspoon holds, half tips medicinal fast, nutmeg doesn’t forgive the way cinnamon does. And the full 24 hours is right, the difference in how the slices hold is real.

My grandmother made an eggnog custard pie every year and it was the thing I actually mourned when I went keto. Not bread, not pasta, that specific pie. Made this last week (yes, in June, because I’ve been craving it for three years) and when I cut into it the next morning and it sliced clean like that, I got a little teary. The custard is exactly what I remember, thick with that warm nutmeg heat. I used oat milk because I was out of almond and it still set up fine. Making this year-round now.

I’ve never made a pie crust from scratch before and I kept waiting for this whole thing to go sideways. The xanthan gum surprised me, it actually rolled and pressed into the pan like real dough without cracking. Left it in the fridge overnight and woke up to something that sliced completely clean. This being my first pie and it coming out this well is kind of blowing my mind.

Reply

Annie Lampella

The xanthan gum shocks everyone the first time. Almond flour should fall apart and it just… rolls.

Reply

Corinne

The no-gelatin part had me skeptical. I’ve made two other keto custard pies this year and both came out like filling soup in a crust once I tried to slice them, so I figured this would be the same. It wasn’t. Set up clean overnight, held its shape when I cut it. I did rush the tempering step because I got impatient, so it’d probably be even better if I actually followed directions. I’ve been eating the keto frozen desserts from the grocery store lately and this actually tasted like dessert. The crust surprised me too (every almond flour crust I’ve tried before crumbled apart when I lifted a slice). Now I want to use it for other fillings.

Reply

Annie Lampella

Rushed tempering that still sets clean means you hit the temp window right even without slowing down. That crust holds chocolate silk too – it’s been on my list for a while.

Jennifer

Making this for a dinner party next weekend, so I want to get ahead on prep. The overnight set works great for my timeline. One question though: does the almond flour crust hold up after sitting with the custard for 24-36 hours? With regular custard pies I add toppings day-of, but wasn’t sure if almond flour softens faster.

Reply

Annie Lampella

The xanthan gum keeps it from going soft. The filling also sets firm before it goes into the crust, so it’s not a wet custard sitting against almond flour for 36 hours. Toppings day-of still.

Reply

Rita V.

I’ve tried two other keto eggnog pie recipes and both used gelatin, which always leaves that weird jiggly texture. The pudding and whipped cream combo here sets up so much cleaner, actually slices like a real pie. Four net carbs is almost suspicious.

Reply

Annie Lampella

Yeah, the gelatin thing was exactly why I went the pudding and whipped cream route. Gelatin sets cold and rubbery and you end up tasting the texture more than the eggnog. Four net carbs is accurate though.

Reply

Christine

Swapped in full-fat coconut milk for the nut milk and the custard set firmer than I expected, clean slices even without a full overnight rest. Not sure if that was the coconut fat or just timing, but I’ll be doing it that way again.

Reply

Annie Lampella

That’s the coconut fat. Full-fat coconut milk has way more saturated fat than most nut milks, which is what firms up a cold-set filling faster. Good to know it slices clean without the full overnight. I’d wondered about that.

Reply

Kevin

Out of xanthan gum and really don’t want to order a whole bag for one recipe. Anything I can sub in for the crust, or will skipping it mess up the texture?

Reply

Annie Lampella

I’d just skip it. Crust gets a little more crumbly without it but still bakes fine. Press it into the pan instead of rolling it out and it holds together well enough to slice.
