If you have been missing real cheesecake since starting a low carb diet, this keto strawberry cheesecake is about to fix that. It has a buttery almond flour crust, a thick and tangy cream cheese filling, and a juicy sugar-free strawberry topping spooned over the top right before you serve it. There is no white sugar, no graham crackers, and no flour anywhere in this cake, yet it still slices clean and tastes like the real thing.
This recipe bakes in the oven rather than skipping the bake step, which is what gives it that dense, classic cheesecake texture instead of a mousse-like one. It takes a bit of patience while it chills, but the actual hands-on work is simple enough for a weeknight.
Why You'll Love This Recipe
- Real cheesecake texture. Baking the filling low and slow gives you a dense, creamy slice instead of a whipped or gelatin-set one.
- Only about 6 grams of net carbs per slice, so it fits comfortably into a keto or low carb day.
- No graham crackers or refined sugar. The crust uses almond flour and the filling uses keto-friendly sweeteners instead.
- Make-ahead friendly. It needs to chill anyway, so it is an easy dessert to have ready before guests arrive.
- Fresh strawberry flavor in both the batter and the topping, not just artificial strawberry extract.
Ingredients You'll Need
For the crust
- 2 cups almond flour
- 1/3 cup unsalted butter, melted
- 1/4 cup granulated erythritol sweetener
- 1/4 teaspoon salt
For the filling
- 24 ounces cream cheese, softened (three 8-ounce blocks)
- 3/4 cup powdered erythritol sweetener
- 1/2 cup sour cream
- 3 large eggs
- 1 1/2 teaspoons vanilla extract
- 1 tablespoon lemon juice
- 1 cup fresh strawberries, pureed
For the topping
- 1 1/2 cups fresh strawberries, sliced
- 2 tablespoons granulated allulose sweetener
A few notes on these ingredients. Almond flour works best finely ground; almond meal will give you a coarser, grittier crust. Powdered erythritol dissolves into the cream cheese far more smoothly than a granulated version, which is why the filling calls for a different form of sweetener than the crust does. If you cannot find powdered erythritol, you can pulse a granulated sweetener in a blender or food processor for about thirty seconds to grind it fine. Allulose is used in the topping because it macerates fruit into a natural, syrupy sauce without turning grainy or crystallizing once it cools, but a granulated erythritol blend will still work in a pinch. Full-fat cream cheese and sour cream are worth using here; the reduced-fat versions tend to make the filling looser and less rich. Frozen strawberries can replace fresh ones in the filling and topping as long as you thaw and drain them well first, since extra liquid can make the batter too loose.
Step-by-Step Instructions
1. Prep the oven and pan. Preheat your oven to 325°F (163°C). Grease a 9 inch springform pan and line the bottom with parchment paper.
2. Make the crust. In a medium bowl, stir together the almond flour, melted butter, granulated erythritol, and salt until the mixture looks like wet sand. Press it firmly and evenly into the bottom of the prepared pan.
3. Bake the crust. Bake the crust for 10 minutes, then remove it from the oven and let it cool slightly while you make the filling.
4. Beat the cream cheese base. In a large bowl, beat the cream cheese until completely smooth and free of lumps, about 2 minutes. Add the powdered erythritol, sour cream, vanilla extract, and lemon juice, and beat again until fully combined.
5. Add the eggs and strawberries. Add the eggs one at a time, beating on low speed just until each one is incorporated. Gently fold in the pureed strawberries by hand so you do not overbeat the batter; too much air in the mix is one of the main reasons cheesecakes crack.
6. Bake the cheesecake. Pour the filling over the cooled crust and smooth the top with a spatula. Bake for 48 minutes, until the edges are set and the center still has a slight jiggle when you nudge the pan.
7. Cool gradually. Turn off the oven, crack the door open, and let the cheesecake sit inside for 1 hour. This slow cooldown is what helps prevent the top from cracking.
8. Chill. Cover the cheesecake and refrigerate it for at least 4 hours, or overnight, until it is fully set all the way through.
9. Make the topping and serve. Toss the sliced strawberries with the allulose and let them sit for 10 minutes to release their juice and turn syrupy. Spoon the topping over the chilled cheesecake just before slicing and serving.
Tips for Best Results
Room temperature ingredients matter more than most people expect. Cold cream cheese and cold eggs do not blend smoothly, and you will end up with small lumps baked right into your cheesecake. Set the cream cheese and eggs out about an hour before you start.
Avoid overmixing once the eggs go in. The goal is just to combine them, not to whip air into the batter. Extra air expands in the oven and collapses as the cake cools, which is a common cause of cracks and sunken centers.
A water bath is optional here but can help if your oven runs hot or unevenly. Wrap the outside of the springform pan in a layer or two of heavy duty foil and set it in a larger roasting pan with about an inch of hot water before baking.
Do not skip the gradual cooldown in step 7. Pulling a hot cheesecake straight from the oven into a cold fridge is one of the fastest ways to crack the top.
If you want the crust a little firmer and more golden, you can bake it closer to 12 minutes in step 3, just keep an eye on the edges so they do not overbrown.
If you are not sure whether the filling is done in step 6, trust the jiggle over the clock. Give the pan a gentle nudge; the outer two inches should look set while only the very center wobbles slightly, similar to firm gelatin. It will finish setting as it cools and chills, so pulling it a touch early is safer than overbaking, which tends to dry out the texture.
A note on sweeteners: erythritol and allulose behave differently from sugar and from each other. Erythritol blends (like Swerve) measure roughly cup for cup like sugar but can crystallize if a dish sits in the fridge too long, which is why powdered erythritol is used in the filling here for a smoother bite. Allulose stays soft and syrupy even when chilled, which is why it works so well in the strawberry topping. If you swap in a monk fruit blend, check the package, since some are twice as sweet as sugar and need less volume.
Storage and Reheating
Store leftover keto strawberry cheesecake covered in the refrigerator for up to 5 days. Keep the strawberry topping separate from the cake if you plan to eat it over several days, since the fruit will release more liquid the longer it sits on top.
This cheesecake also freezes well. Slice it first, then wrap each piece individually in plastic wrap and store in an airtight container or freezer bag for up to 2 months. Thaw a slice overnight in the refrigerator, and add the fresh strawberry topping after thawing rather than before freezing it.
There is no need to reheat this dessert; it is meant to be served cold or at room temperature straight from the fridge.
Frequently Asked Questions
How many net carbs are in a slice? One slice has about 6 grams of net carbs, based on the recipe being cut into 12 servings. The exact number will shift slightly depending on the sweetener brand you use, since some sugar alcohols are counted differently than others.
Can I use frozen strawberries instead of fresh? Yes. Thaw them completely and drain off the excess liquid before pureeing or slicing, otherwise the filling can turn out too loose and the topping too watery.
Why did my cheesecake crack on top? Cracking is almost always caused by overmixing the batter, baking at too high a temperature, or cooling the cake too quickly. Following the gradual oven cooldown in step 7 solves this in most cases.
Can I make this cheesecake ahead of time? Yes, and it actually works better that way. Since it needs at least 4 hours to chill, making it the night before you plan to serve it gives you one less thing to worry about on the day itself.
Do I have to use a springform pan? A springform pan makes it much easier to remove the cheesecake without damaging the crust, so it is strongly recommended for this recipe. If you only have a regular cake pan, line it with parchment paper that overhangs the sides so you can lift the cheesecake out once it is fully chilled.
Is this cheesecake gluten-free? Yes, the crust is made entirely from almond flour with no wheat flour or graham crackers, so the recipe is naturally gluten-free as written.
