Keto Raspberry No-Bake Cheesecake

Every bite of this keto raspberry no-bake cheesecake is mousse-light and creamy at 4.4g net carbs. My from-scratch raspberry sauce makes it taste like it came from a bakery, and it looks like it took hours when it's actually no-bake.

So you’re not Martha Stewart and you don’t want to spend hours in the kitchen making a baked cheesecake, only to have it crack down the middle or come out dense as a brick. I’ve been there. This is the recipe I reach for when I want a real, show-stopping cheesecake without babysitting an oven.

What makes this recipe different?

  • The texture is mousse-like, not dense. Most cheesecake recipes like this give you a block of sweetened cream cheese and call it done. I spent a long time getting the mixing sequence right. You fold in the sour cream first, then whip cold heavy cream in on high for a full 5 minutes. That order matters. It’s what creates the airy, silky filling that’s closer to a French mousse than a typical cheesecake.
  • The raspberry sauce is strained smooth. I cook down the berries with sweetener and lemon zest, then push everything through a fine mesh strainer to remove every seed and bit of pulp. You end up with about 2/3 cup of pure raspberry puree that sets on its own once chilled. No gelatin needed. A reader of mine stirred about a third of it into the batter before pouring, and the swirl through each slice turned out gorgeous. About a third of the sauce is the right ratio. Any more and the raspberry starts competing with the cream cheese.
  • The crust has actual flavor. I add oat fiber to the almond flour base purely for taste. It gives the crust a slightly toasty, graham-cracker quality that straight almond flour doesn’t have. Same technique I use for my almond flour cookies.
  • You genuinely don’t need an oven. Your oven can be broken and you’ll still end up with a low carb cheesecake that looks like it came from a bakery. All you need is a couple of bowls, an electric mixer, and a springform pan. One of my readers even used parchment-lined muffin cups and said the crust-to-filling ratio was better that way.
  • It holds up for days. I’ve made this on a Sunday and sliced into it on Wednesday without any texture loss. It also freezes well if you want to prep for a holiday. If you like make-ahead keto desserts, this sits alongside my mini cheesecakes and chocolate trifle as a freezer-friendly option.

I originally made this as a Valentine’s Day dessert (you can draw little raspberry hearts on top with a toothpick), but my family started requesting it year-round. If you love no-bake treats, this is the one that gets asked for most at my house.

What I'd swap (and what I wouldn't)

Raspberry sauce swaps

I’ve tested this with strawberries, blackberries, and blueberries, and they all work. Blackberries produce the richest color. You could also skip the berry sauce entirely and drizzle sugar-free chocolate or caramel on top instead. The cooked sauce sets on its own once chilled, no gelatin needed. For an even firmer topping, dissolve half a teaspoon of unflavored gelatin in a tablespoon of water and stir it into the warm sauce.

Crust ingredient swaps

  • Almond flour: Coconut flour or lupin flour both work, but you’ll need less (coconut flour absorbs more liquid). I prefer almond flour here for the texture.
  • Oat fiber: Just use more almond flour if you don’t have it. The oat fiber adds a subtle toasty flavor I really like, but the crust holds together fine without it.
  • Butter: Melted coconut oil works as a 1:1 swap.
  • Brown sugar sweetener: Regular granulated sweetener is fine. I use brown sugar style because it gives the crust a hint of caramel.

Cheesecake filling swaps

  • Lemon juice and zest: Lime works well too, or omit citrus entirely for a more neutral flavor. I always include it because the acid brightens the filling.
  • Sour cream: Plain Greek yogurt gives a similar tangy note. I’ve used both, and the texture difference is minimal.
  • Heavy cream: Coconut cream whips up the same way. Good option if you’re dairy-free, and my protein cheesecake uses a similar swap.

How I store it (and how long it really lasts)

Refrigerator storage

I cover the pan tightly with plastic wrap and keep it in the fridge for up to 4 days. The texture actually improves after the first night as everything firms up and the flavors meld together. Keep it cold though. If it sits at room temperature too long, the filling softens and slicing gets messy.

Freezer storage

Wrap the chilled cheesecake in plastic wrap first, then aluminum foil to prevent freezer burn. I’ve frozen this for up to 2 months without any texture issues. Thaw overnight in the refrigerator before serving. If you like making low carb desserts in bulk, this freezes as well as my ice cream cake. I usually slice before freezing so I can pull out individual servings.

How to make this raspberry cheesecake

  1. Make the raspberry sauce. Combine frozen or fresh raspberries in a saucepan with sugar-free sweetener and lemon zest. I usually use frozen. They break down faster and release more juice, so the sauce comes together quicker. Once thickened, push it through a fine mesh strainer to remove the pulp and seeds. You’ll end up with about 2/3 cup of smooth puree. Any berry works here. I’ve done blackberries and blueberries, and you could make a strawberry version like the sauce on my keto strawberry cake.
  2. Press in the crust. Combine almond flour, oat fiber, brown sugar sweetener, salt, melted butter, and vanilla extract. Press the mixture into a 9-inch springform pan along the bottom and about half an inch up the sides. No oven needed. If you don’t have a springform pan, parchment-lined muffin cups work surprisingly well (a reader of mine tested this and they slid right out).
  3. Whip the filling. Beat cream cheese, sweetener, lemon juice, lemon zest, vanilla, and salt until smooth and fluffy. Fold in sour cream, then slowly add cold heavy cream and whip on high for about 5 minutes. The mixing order matters here. Adding the sour cream before the cream is what gives this filling its mousse-like texture instead of a dense cream cheese block.

Step by Step Instructions

  1. Get sauced first

    To a medium saucepan, add raspberries, sweetener and lemon zest. Heat to medium heat, stirring frequently to break up the raspberries and to keep them from burning. Once the mixture comes to a simmer, increase heat to medium high and cook, while stirring, until thickened (about 5 minutes).

    For this step

    • 12 oz fresh or frozen raspberries
    • 1/4 cup sugar-free sweetener
    • 1 teaspoon lemon zest
    A spoon resting in a saucepan with raspberry puree.
  2. Strain out the seeds & pulp

    Pour the raspberry mixture into a mesh sieve or strainer set over a bowl. Using the back of a spoon, press the raspberry puree through the strainer, occasionally scraping the underside to allow for more to pass through. Continue dragging and pressing the puree into the strainer with the back of a spoon until you are left with mostly seeds. Discard the seeds & pulp. Chill the syrup puree in the refrigerator while preparing the cheesecake.

  3. Press in crust

    Spray the bottom and sides of a 9″ or smaller springform pan with cooking spray. Set aside. To make the crust, add almond flour, oat fiber, brown sugar sweetener and salt to a large bowl. Mix to combine. Stir in vanilla extract to the melted butter. Then add to dry ingredients. Mix until combined. Add crumb mixture to the springform pan and evenly press the crumb mixture into the bottom of the pan and up the sides about ½-1 inch. Refrigerate crust while preparing the filling.

    For this step

    • 1 ¼ cup almond flour
    • 3 tablespoons oat fiber
    • 2 tablespoons brown sugar-free sweetener
    • 1/8 teaspoon salt
    • 6 tablespoons unsalted butter, melted
    • 1/2 teaspoon vanilla extract
    A no-bake crust pressed into a springform pan.
  4. Cheesecake mixture

    To a large bowl, add softened cream cheese, sweetener, lemon juice, lemon zest, vanilla extract and salt. Using an electric mixer, mix on high speed until smooth and fluffy (about 2-3 minutes). Stir in sour cream until combined. Slowly add in cold heavy whipping cream and whip on low speed until combined. Then increase speed to high and continue to whip until thick and fluffy (about 5 minutes).

    For this step

    • 16 oz cream cheese, softened to room temperature
    • 3/4 cup sugar-free sweetener
    • 1 tablespoon lemon juice
    • 1 teaspoon lemon zest
    • 1 teaspoon vanilla extract
    • 1/8 teaspoon salt
    • 1/2 cup sour cream
    • 1 cup heavy whipping cream, cold

  5. Pour into crust

    Pour the cheesecake filling into the prepared crust and smooth the top using a spatula.

  6. Swirl it into hearts

    Dot the top of the cheesecake with small dots of syrup in concentric circles. Using a toothpick, gently pull through the dots of sauce, creating a heart shape. Alternate which direction you pull the sauce in, creating swirls. Refrigerator for at least 8 hours or overnight.

Frequently Asked Questions

Why isn't my cheesecake setting up after overnight chilling?

I've had this happen when my heavy cream wasn't cold enough before whipping. Use it straight from the fridge, and whip on high for a full 5 minutes after adding it. If your filling is still soft after 8 hours, move it to the freezer for 2-3 hours. That usually firms everything up. Also, using a pan larger than 9 inches spreads the filling too thin to set properly.

Do I need to use powdered sweetener or can I use granulated?

I always use powdered sweetener in the filling because granulated erythritol doesn't fully dissolve and the texture goes grainy. If all you have is granulated, pulse it in a blender for about 30 seconds to powder it yourself. That's what I do when I run out. For the crust, granulated is fine since the butter melts everything together.

Can I make this crustless for fewer carbs?

I've done it. Pour the filling straight into a greased pan or individual ramekins, chill, and top with the raspberry sauce. You cut a few grams of carbs per serving and it's still keto-friendly. The texture is pure mousse at that point, which is a different dessert but a good one.

There’s this moment when a fork goes through a good no-bake cheesecake and it just gives, no resistance, just this cool creamy softness. That’s what my sister-in-law kept talking about afterward. I brought this to her bridal shower and she’s done keto on and off for years but said she’d never had one that held up to slicing that cleanly. Her friend Meg showed up with a backup store-bought cheesecake just in case, and by the end of the night Meg was asking me to text her the recipe. I sent her the link and she asked ‘is it complicated’ and I told her the hardest part is the raspberry sauce and she goes ‘how hard’ and I said you strain it through a sieve and she said ‘I can do that’.

She’s right, the sieve is the hardest part. I love that it sliced clean for a whole shower!

Steve, store-bought raspberry cheesecake is like 30g a slice. That’s exactly why I keep making this one.

Side note: pull the cream cheese out an hour early. No lumps.

Good catch, cold cream cheese is where most lumps start, I leave mine out for like 90 minutes when I remember.

This one actually got me, and I don’t say that about keto desserts anymore. Cheesecake was the thing I stopped looking for in year one. The texture never worked, and I told myself I was past it. The filling here is mousse-light, that texture I thought I was done having. And when the raspberry sauce comes through the sieve, that color and glossiness, it looks like something I’d have bought at an actual bakery. I stirred an extra bit of lemon zest into the filling and it opened everything up. I’m making this for a family dinner next month and not saying anything about it ahead of time. Annie, this one I didn’t know I still wanted.

That streak of deep red across the top is what gets me every time I cut into it. My grandmother made a raspberry cheesecake from scratch every August when the berries were good, and I’d stopped expecting to find anything that felt like that after going keto. The from-scratch sauce is why this one works. Running the raspberries through a sieve after cooking them down with lemon zest gives you something glossy and concentrated that no store-bought topping touches, and that’s how I remember hers. The mousse-light filling was the other surprise. Her version had that texture where it should feel heavier than it does, and I’d always assumed that was a full-sugar thing. Made it three times now and not stopping.

Annie Lampella

Your grandmother knew what she was doing. I put the sieve step in specifically for that glossy finish, and the pulp version just does not come close. Glad it brought something back, Tricia.

Mousse-light is exactly what this is, and I wasn’t expecting it from a no-bake. First springform pan I’ve ever used and it held together fine. One thing: the lemon zest in the filling competes a little with the raspberry. I’d cut it in half. The sauce handles that.

Reply

Annie Lampella

The lemon zest note is fair. I keep it in the filling for a little brightness but half a teaspoon would let the sauce do more of that work.

My daughter doesn’t really pay attention to what’s keto and what isn’t, she just wants dessert that actually tastes like dessert, so I was watching her face when she took the first bite. She stopped and asked if I had made the sauce myself, because she could tell it tasted different from anything store-bought, and I am not someone who usually makes things from scratch. I had to walk her through the whole straining-through-the-sieve step and she seemed genuinely impressed, which does not happen often with food I make. The filling surprised me too, I kept bracing for that weird aftertaste that shows up in a lot of keto desserts but it never came. It really is mousse-light like the recipe says, I thought that was just recipe writing but the texture is actually different from a regular dense cheesecake. Already have a second batch penciled in for a birthday dinner next month.

Annie Lampella

Ha. The sieve does that. One real technique and suddenly you’re the person who makes sauce from scratch.

Third batch and I used fresh raspberries this time instead of frozen. Way less watery, and the color was actually pink-red instead of that brownish purple. Still figuring out the crust but honestly the filling makes up for it.

Reply

Annie Lampella

Fresh reads cleaner color-wise, yeah. Frozen is faster because the berries break down quicker and release more juice, but you trade off that red. For the crust, press it thin and freeze it 30 minutes before the filling goes in. That’s what finally worked for mine.

Reply

My daughter who always skips dessert came back for a second slice after I mentioned it was only 4 net carbs, then spent the next five minutes reading through the ingredient list like she was fact-checking me. I think the from-scratch raspberry sauce is what got her. She asked me to make it again this weekend.

Reply

Annie Lampella

The audit after the second slice is my favorite part. She already voted with her stomach, then went looking for a reason to justify it. The raspberry sauce has that effect.

Reply

Heather

Added an extra teaspoon of lemon zest to the filling and it gave the whole thing a sharper edge that balanced out how sweet the raspberry sauce ran.

Reply

Annie Lampella

Two teaspoons in the filling, yeah. The sauce can go pretty sweet depending on the batch of berries. I’ll probably do two next time.

Reply

Crystal

Used fresh raspberries from the farmers market instead of frozen, and backed off the sweetener to 3 tablespoons since fresh ones don’t need as much. The sauce came out a deeper color, almost jammy, which I liked better than the frozen version. Crust held up fine after two days in the fridge too, which surprised me given the oat fiber. Saving this for summer fruit variations.

Reply

Annie Lampella

Yeah, fresh reads darker, almost more of a jam. I usually keep the sweetener around 3 tablespoons when the berries are actually ripe.

Reply

Mia

My daughter grabbed a slice before I mentioned it was keto, and her only note was that the raspberry sauce tasted ‘almost too fresh’ for a no-bake. Coming from someone who picks cheesecake apart, that landed. Would give it 5 except the crust crumbled on me when slicing, so I’m pressing it a bit firmer next time.

Reply

Annie Lampella

Yeah, press hard. I throw mine in the freezer for an hour before I cut it and it comes out clean.

Reply

Marco

Never used a springform pan before, almost bailed. But the crust pressed in easily and the raspberry sauce was done in like 5 minutes. The filling is SO light, I kept bracing for that fake-sweet aftertaste and it just never came. Lemon zest gets a little lost though. I’d probably double it next time.

Reply

Annie Lampella

Yeah, double the zest. Cream cheese just absorbs it.

My husband was just diagnosed with a dairy intolerance so I’ve been reworking our usual keto desserts, and this one caught my eye. The filling swap seems easy enough (dairy-free cream cheese for regular), but I’m less sure about the butter in the almond flour crust. That’s doing most of the binding. I usually reach for coconut oil but I’ve had greasy crusts with it before, especially no-bake where there’s nothing to cook off the excess. My bigger concern is whether dairy-free cream cheese sets up firm enough to slice. I’m making this for Easter, so it actually needs to hold together. If it ends up mousse-like instead of cheesecake-firm, is there anything I can do to help it set?

Reply

Annie Lampella

Dairy-free cream cheese varies a lot by brand for firmness. Violife and Kite Hill both set up closer to regular cream cheese than the store-brand versions, which tend to stay mousse-soft. If you want insurance for Easter, bloom a teaspoon of unflavored gelatin in 2 tablespoons of warm water and mix it into the filling before you chill it. That’ll get you clean slices. For the crust, try vegan butter instead of coconut oil. Same binding, none of the grease issue.

So I don’t own a springform pan and went with parchment-lined muffin cups instead, mostly just hoping they’d come out without falling apart. They slid right out clean, which I wasn’t expecting, and the crust-to-filling ratio ends up completely different this way (more crust per bite, which I like way more than I thought I would). The raspberry sauce pools on each little cup and the lemon zest came through so much stronger than expected. I froze half the batch before adding the sauce, thawed them the next day, and the crust had firmed up even more overnight. Anyway, in case anyone else is working around the springform pan thing.

Reply

Annie Lampella

Freezing before the sauce is smart. The crust stays crisp and the sauce pools instead of soaking in. And yeah, smaller portion concentrates the zest.
