It may surprise you, but cheesecakes are one of the easiest desserts to “keto-fy”. A classic cheesecake uses many keto-friendly ingredients, like eggs, cream cheese, and/or heavy cream. With just a few minor tweaks, my keto cheesecake recipe looks and tastes like the real thing!
Table of Contents
Why I 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 are needed!
- The cheesecake is so smooth, rich, and creamy that 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.
Ingredients needed
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.
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 allulose 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
I’ve included step-by-step photos below to make this recipe easy to follow at home. For the full printable recipe instructions and ingredient quantities, scroll to the recipe card at the bottom of this post.
Step 1- Make the crust. Add your cookies to 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 to a 9-inch spring-form cake pan and refrigerate it.
Step 2- 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.
Step 3- 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.
What to serve with this dessert?
Take your cheesecake up a notch by serving it with some keto ice cream, keto whipped cream, a drizzle of sugar free chocolate syrup or a light dusting of keto powdered sugar.
Arman’s recipe tips
- Avoid overbaking the cheesecake, as it continues to cook as it cools. 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.
Storage 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.
Frequently Asked Questions
Full-fat cream cheeses, including the Philadelphia brand, are all suitable for a low-carb diet. They are high in fat and protein, with very few carbs. Avoid using reduced-fat or fat-free cream cheese, as the fat is replaced with extra carbs.
Monk fruit sweetener and allulose are fantastic keto sweeteners that can replace sugar in cheesecakes. If you are making a flavored cheesecake, using a brown sugar substitute intensifies the flavor.
Each slice of cheesecake in this recipe has just 3 grams of net carbs.
If you make this cheesecake without the cookie crust, there are just 1.5 grams of net carbs per slice.

Uh for me it seems too high in calories I mean too heavy. But maybe I can make it for a friend.
Where could I find keto crumbs?

Curiosity question: has anyone ever inquired about making a Crustless Keto Cheesecake? I make a Crustless Pumpkin pie w/ out encountering any adverse issues. Just curious.

Thank you
Love all your keto recipes keep them coming💙💙💙
Outstanding recipe. Simply outstanding. I used the Catalina crunch honey graham cereal with the melted butter for the crust. I also decreased the vanilla to 1.5 teaspoons, just did. Also added the eggs one at a time, mix until just incorporated each time. Baked and left in the oven for an hour, room temperature for 2 hours just like the recipe calls for. These steps will really prevent the top from cracking. So so excited to find this recipe. Thank you, thank you!
This cheesecake recipe is absolutely delicious. It really is very tasty and creamy and so easy to make. Will use lemon juice in place of the vanilla next time for a different flavour.
Such a fantastic cheesecake recipe – and it’s KETO! I didn’t have that much butter on hand so I actually used coconut oil instead, just cut in half. Cooked perfectly however for me, my cheesecake burned a bit ontop so I’ll cook it for 40 mins next time instead of 50. For the crust, I crushed up some keto cookies I bought from Aldis and it was such a great pair. Next time I’ll bake this with the cookie crust recommended.
This is the best cheesecake that I’ve ever made. It’s perfectly sweet and creamy. I used the suggested peanut butter cookies for the crust and mixed with roasted pecans (2 cup cookie crumbs,1/2 cup pecans). I’m so glad I took the extra step to bake the peanut butter cookies because I think the crust is too good to skip!
Cheesecake is my favourite cake but I never tried in keto version.
very good recipe!!!! everyone loved it!!!
I’m type II diabetic ( or more accurately called “insulin resistant ) so I’m using allulouse for my sweetener. I wear a continuous glucose monitor. As unbelievable as it is my blood sugar goes DOWN after eating my cheesecake (your recipe – THANK YOU!!!). See video called “A Sugar Substitute That’s Good For You? The Science Behind Allulose” w Dr. Benjamin Bikman (my new hero!)
