These buttery small-batch keto sugar cookies come topped with pink Lofthouse-style buttercream at 1.1g net carbs per cookie. When I want a cookie (or three), I don't have to bake a whole batch to scratch the itch.
I make my full batch sugar cookies for holidays and parties, but most nights I just want one or two. That’s the whole point of this recipe. Six cookies, one bowl, about 20 minutes of actual work. No leftovers staring me down from the counter for three days.
How these cookies differ from the others
Sized for a craving, not a crowd: I developed this after too many nights making a full recipe and eating half the tray. With a smaller yield, I get my fix and the kitchen is clean before the next show starts.
Lofthouse copycat frosting: The buttercream tinted pink, just like those soft grocery store Lofthouse cookies. Reader Amber has made these six times and noticed the frosting develops a dense, almost fudgy texture once it chills. She’s right. Cold from the fridge, it firms up into something better than the original.
1.1g net carbs per cookie: I held off on putting macros in the intro for too long. Now you know upfront: these keto sugar cookies fit your day without negotiation.
Nut-free option tested: A reader swapped sunflower seed flour for almond flour and I confirmed it works. Add 30 extra seconds to your bake time. Texture is a little denser but solid.
The anti-spread trick took me the longest to figure out. Small dough warms fast in your hands, so I do two separate chills: once after rolling (15 minutes) and again after cutting shapes (5 minutes on the baking tray). Skip either chill and the cookies spread flat. I learned this the hard way after three rounds that came out looking like low carb pancakes.
The mother-in-law story is real, by the way. She had Lofthouse cookies out for the kids, and I sat there staring at them for an hour. Came home and made these at 9pm out of pure spite. Ain’t nobody got time to make a big batch of cookies at 9pm, but a small batch? That I can handle.
Ways to customize these cookies
Think this recipe is just vanilla and pink frosting? Here’s what I’ve tried.
Almond extract instead of vanilla: My mother-in-law adds this to her cookies and they vanish. One-for-one swap, same amount.
Citrus zest in the dough: I’ve grated lemon and orange zest directly into the batter. Lemon is my favorite. About half a teaspoon does it without overpowering the butter.
Warm spices: A pinch of cinnamon or cardamom turns these into a Fall cookie. I add it with the dry ingredients.
Chopped nuts: My mom put nuts in every cookie she made. Almonds, walnuts, pecans. She called it “a must.” I fold in about a tablespoon of chopped pecans when I’m feeling nostalgic.
Air fryer option: I’ve tested these at 325F for 5-6 minutes in the air fryer. Skip the baking tray chill step. If you already bake keto cookies in the air fryer, try my air fryer chocolate chip cookies too.
Different frostings: Swap the vanilla buttercream for a chocolate version or go with a cream cheese base. I’ve done both and they pair well with the simple cookie underneath.
One giant cookie: I press the whole dough ball into one big cookie, about half an inch thick, and bake it at 350F. I check at 10 minutes; it usually needs 10-12 minutes total depending on thickness. Let it cool completely on the tray before touching it, same as the smaller ones.
How to store and freeze these cookies
If you didn’t demolish this entire small batch in one sitting (no judgment, I have), here’s how to keep what’s left.
Unfrosted cookies keep at room temperature for 1-2 days in a sealed container. After that they start drying out. In the fridge, they last 3-5 days.
Frosted cookies need the fridge. The buttercream softens at room temp and gets messy. Refrigerated, they hold up for 3-5 days and the frosting actually improves (that fudgy texture Amber mentioned).
You can freeze both the dough and baked cookies. For dough, roll it into a ball, flatten, and store in a freezer bag for up to 3 months. Thaw at room temperature for 10-15 minutes, then cut and bake as usual. For baked cookies (frosted or not), freeze flat on a tray first, then stack with parchment between layers. They keep for about 2 months. Thaw in the fridge overnight. If you want cookies that hold up even better for meal prep, my no-bake cookies are practically indestructible in the fridge.
How to make small batch sugar cookies from scratch
Everything happens in one bowl, which is the best part of making a small batch. Cream the wet ingredients, add the dry, roll, cut, bake. I picked up a tip from a reader after her second batch: smash the dough ball flat with your palm before putting it between parchment sheets. With this little dough, the rolling pin alone leaves thick edges and thin centers. The palm press evens it out and the circles cut much cleaner.
In a small bowl, cream the butter and sweetener together with an electric mixer or use a fork. Stir in the beaten egg and vanilla.
For this step
2 tablespoons unsalted butter, softened to room temperature
2 tablespoons sugar-free sweetener
2 tablespoons beaten egg
1/2 teaspoon vanilla extract
2
Mix in dry ingredients
Add almond flour, baking powder and salt. Stir to combine.
For this step
3/4 cup blanched, super-fine almond flour
1/2 teaspoon baking powder
1/8 teaspoon salt
3
Roll out cookie dough
Mold cookie dough into a ball and place in between two sheets of parchment paper. Roll out the dough using a rolling pin until the dough is about ¼ inch (~½ cm) thick. Place into the refrigerator for 15 minutes. Preheat oven to 350°F.
4
Cut into shapes
Remove cookie dough from the refrigerator. Carefully punch out round cookies with cookie cutter. Use a spatula to transfer the cookie to a parchment lined baking tray. If dough seems too soft, put back in the refrigerator for 5-10 more minutes or add in another tablespoon or two of almond flour.
5
Bake the cookies
Refrigerate baking tray with cookies for 5 minutes before baking. This will keep them from spreading too much while baking. Then transfer to the oven and bake at 350°F for 7 minutes or just until the edges ever so slightly turn golden brown. Remove from oven and let cookies cool completely on the tray before handling.
6
Make the frosting while the cookies bake
To make the frosting, mix butter, powdered sweetener and vanilla using an electric mixer in a small bowl. Add pink food coloring until a soft pink develops.
For this step
4 tablespoons unsalted butter, softened
3/4 cup powdered sugar-free sweetener
1 teaspoon milk of choice (nut milk, cow's milk, heavy cream, etc(
3/4 teaspoon vanilla extract
7
It's all about the frost
Spread or pipe frosting on each cookie. Top with sprinkles.

Frequently Asked Questions
What sugar-free sweetener works best for these?
I use allulose for the cookie dough and a powdered monk fruit blend for the frosting. Allulose browns like real sugar and keeps the cookies soft. For the frosting, you need a powdered sweetener or it gets gritty. I've tried erythritol and it works but has a slight cooling aftertaste. My combo is allulose in the dough, powdered monk fruit in the frosting.
Can I make these dairy-free with coconut oil?
I've subbed coconut oil for butter in the cookie dough and it works. Use the same amount, just make sure it's solid (not melted) so the dough holds its shape. The flavor shifts slightly toward coconut, which I actually like with the vanilla. For the frosting, coconut oil makes it softer, so I refrigerate the frosted cookies for at least 20 minutes before eating.
Can I bake these in an air fryer?
I've done it. Set your air fryer to 325F and bake for 5-6 minutes. You don't need to refrigerate the baking tray first since the air fryer basket doesn't hold heat the same way, but I do still chill the cut dough for 5 minutes before transferring, or they spread. The cookies brown a little faster on top than they do in the oven.
Can I double this to make a full batch?
You could, but I'd just use my full batch recipe at that point since the ratios are already scaled and tested. This recipe is tuned for a yield of six cookies, and doubling doesn't always scale cleanly. Or if you want variety, my almond flour chocolate chip cookies are another good option to have in the rotation.
If you brown the butter, let it set back up before you cream it or the dough goes slack. Mine did, and I still liked the nuttier edge. Your small batch recipes are my favorite on the site, Annie.
Annie, your recipes never let me down! These taste just like the cookies I grew up begging for at the grocery store bakery. I figured that was gone for good on keto. SO good!
Pink frosting got my mom’s attention before she even tasted one. She’s been skeptical of keto baking for two years, so that’s saying something. Four stars from her, the cutting step was trickier than expected, and thin almond flour doesn’t forgive rushing the chill.
Confession: sugar cookies were the one thing I never expected keto to get right. Pies, cheesecake, brownies, sure, but a thin frosted sugar cookie is a different kind of specific. These have that slight give in the center instead of the crisp snap I’d settled for with most almond flour cookies. The pink buttercream is what finally got me, though. You make it and it just looks right. After two years of lowered expectations, I wasn’t ready for that.
The give in the center is what I kept testing for. Almond flour cookies almost always skip straight to crisp, and finding that soft window without going gummy took a lot of rounds. The double chill is what finally held it.
Doubled the recipe before game night because six felt like a tease for eight people. The frosting color is what got everyone. One person held hers up, said it looked exactly like a Lofthouse, and then just waited for the catch. When I told her under 2g net carbs she made me repeat it twice. That pink is doing a lot of work.
I make one batch on Sunday, keep the cookies unfrosted in an airtight container, and the buttercream goes in a small jar in the fridge. Frost one or two at a time throughout the week. Fresh every single time, instead of sitting five days with the icing slowly softening into the cookie. Didn’t expect this, but the texture actually gets better by day two or three, firmer and less crumbly than right out of the oven. I started this mostly for the carb tracking (1.1g per cookie is about as precise as dessert gets), but the separate frosting thing ended up being the bigger win.
I’m stealing your separate frosting system, Alex. The texture settling by day two is real with almond flour cookies, I just never thought to time the frosting around it.
Kept waiting for the almond flour to betray me (usually it does with cookies this thin) but the texture held, and that pink buttercream is weirdly spot-on for Lofthouse. Only minus is I need to double the batch because six cookies is not enough.
The double chill is what holds thin almond flour cookies together. Six is genuinely not enough, I get it. My full batch sugar cookie recipe is already scaled if you want real cookies without doubling this one.
Growing up, my mom would put a pack of those pink Lofthouse cookies in the cart every single time we went to the grocery store. That soft, almost-too-sweet frosting was what a treat was supposed to feel like. I’ve been low-carb for three years now and kind of just accepted that version of dessert was behind me. Then I made these, and the buttercream with a little pink food coloring was so close that I stood at the counter eating the first one just trying to figure out if it actually tasted like I remembered or if I just wanted it to. It did. The dough is a bit more delicate than I expected when cutting out shapes, so I’d be gentle with re-rolling, but the flavor really is there. I did not expect to cry over a sugar cookie.
That last line. The frosting was built around that Lofthouse memory. For re-rolling, pop the dough back in the fridge for 5 minutes when it warms up, cuts so much cleaner.
Keto baking has let me down so many times. Dense and gummy, every time. But these actually worked! I almost skipped the refrigerating-the-tray tip and I’m really glad I didn’t (the edges held their shape so cleanly). Mine came out thicker than your photos but the soft center was still there, which is what I was worried about losing. Quick question: would monk fruit work for the frosting, or does the powdered erythritol matter for the piping texture?
Batch six and I have this exactly where I want it. Added 1/4 teaspoon of almond extract to the buttercream and the frosting is now the whole point. The cookie is solid on its own but that one tweak made these a weekly thing. Dough comes together fast, under 30 minutes, and the small batch size is freaking perfect because I want four cookies, not forty.
My daughter came downstairs, saw these on the counter, and immediately asked if I bought Lofthouse cookies. Girl knows her baked goods. Only reason it’s not 5 stars — I want the buttercream a bit thicker next time.
The cookies themselves are freaking perfect. That almond flour base bakes up crispy on the edges and I was genuinely shocked at how buttery they taste for something with so little butter in it. My one note: the buttercream recipe makes way more frosting than you need for six cookies, so unless you’re planning to eat the rest with a spoon (not judging), cut it in half. Still making these every week though.
Made these maybe six times now and keep coming back whenever I want something sweet but can’t justify a full batch sitting on the counter. Last time I added a drop of almond extract into the buttercream and the whole thing shifted (in a good way), that slightly floral note plays really well with the pink frosting. Can’t make them without it anymore.
Almond extract belongs in that buttercream. I’ve been adding it to the dough when I want more of that flavor, never thought to move it to the frosting. Fixing that today.
Cookie base is spot on, but I’d pull back on the powdered sweetener in the frosting by a tablespoon. With Lakanto it tips cloying fast, and this batch was right on the edge. Still made them twice this month, so clearly works.
Lakanto does run sweet in frosting. I switched to a powdered monk fruit blend and it’s noticeably milder, so the tablespoon pullback makes sense if you’re sticking with Lakanto. Two batches in a month is enough to call it.
Batch six and counting. I still think about these on the drive home when I want something sweet but don’t want the whole production. The frosting gets this dense, almost fudgy texture once it chills. That part keeps me coming back.
Made something similar in the air fryer before and want to try it with these. Do I still refrigerate the baking sheet for 5 minutes before baking, or does that step not really carry over to the air fryer?
Skip the tray chill. The air fryer basket doesn’t hold heat the same way a metal sheet does. Still chill the cut dough before dropping it in though. 325F, 5-6 minutes.
Fully expected cardboard. Every other almond flour cookie I’ve tried has been. But these are actually buttery? Kept eating them trying to figure out why. Not perfect, but closer to a real sugar cookie than anything I’ve managed keto.
It’s the allulose in the dough. Keeps them soft instead of that dry crumble most almond flour cookies have. Still not a Lofthouse but closer than I expected when I first tested them too.
