This keto cheesecake recipe is smooth, rich, creamy, and made with just 6 ingredients! Ready in less than an hour, a secret trick guarantees a perfectly baked cheesecake every single time!
It’s no secret that I have a raging sweet tooth.
Even though I follow a ketogenic diet, desserts play a very important role.
Is cheesecake ok on a keto diet?
A classic cheesecake uses many keto friendly ingredients, like eggs, cream cheese, and/or heavy cream. While sugar and thickeners (like flour) aren’t suitable for a keto diet, by making some easy swaps, you can easily enjoy a keto cheesecake recipe.
Why you’ll love this recipe-
- It needs just 6 ingredients total, and that is including the crust.
- It’s made using simple and affordable ingredients. No hard-to-find flours, sweeteners, or additions needed!
- The cheesecake is so smooth, rich, and creamy, even those who don’t follow a keto diet will be obsessed.
- It takes less than an hour to bake, which is nothing compared to other cheesecakes out there.
As someone who grew up enjoying the famous Cheesecake Factory desserts, I’m stoked I can make my own homemade version while still keeping it low carb and sugar free.
Sugar free cheesecake ingredients
For the cheesecake crust
- Keto cookies- While for most keto pies and cheesecake recipes we use a keto graham cracker crust, we found this cheesecake worked better using crushed peanut butter cookies. If you have a peanut allergy, this works just as well with crushed almond butter cookies.
- Butter- unsalted butter measured in its melted state.
For the filling
- Cream cheese- Softened and at room temperature. Also, try to use cream cheese that comes from a block instead of a tub. It contains very few additives (if any) and yields a much creamier dessert.
- Sour cream- Like the cream cheese, your sour cream should be at room temperature.
- Superfine sugar substitute- Also known as caster sugar. Superfine sugar has the consistency between standard sugar and powdered sugar and you can easily make it yourself. Simply blend erythritol until it has a finer texture.
- Eggs- Room temperature.
- Vanilla extract- A classic vanilla cheesecake should ALWAYS have a hint of vanilla.
How to make a keto cheesecake
Start by preparing the crust. Add your cookies into a food processor and break them down until a fine consistency remains. Place the crushed cookies into a bowl and mix through the melted butter. Transfer the mixture into a 9-inch spring-form cake pan and refrigerate it.
Next, make the cheesecake filling. Add the cream cheese, sour cream and sugar substitute into a high speed blender and pulse until smooth. Add the eggs and vanilla, and blend once more until combined.
Now, transfer the filling over the crust and bake for 50-55 minutes, or until the cheesecake has set in the middle. Let the cheesecake cool completely, before refrigerating it for at least four hours, to firm up beautifully.
Tips to make the best recipe
- Avoid over-baking the cheesecake, as it continues to cook as it is cooling down. Once it is mostly set in the middle, you can be confident it will be fully cooked once it has cooled.
- Cooling your cheesecake in the still-warm oven helps it firm up even better than when left at room temperature. Be sure to keep the oven door slightly ajar, otherwise, you will be left with a dense dessert!
- Do not refrigerate the cheesecake until it has cooled completely. This will avoid any potential cracks on the top.
Storing and freezing instructions
- To store: Low carb cheesecake should always be stored in the refrigerator, covered. It will keep well for at least one week.
- To freeze: Place leftover slices of the cheesecake in a shallow container and store them in the freezer for up to 6 months. Be sure to thaw it completely before enjoying it.

Erythritol, monk fruit sweetener, and allulose are all fantastic keto sweeteners that can replace sugar in cheesecakes. If you are making a flavored cheesecake, using a brown sugar substitute intensifies the flavor.
