keto cheesecake

It’s no secret that I have a raging sweet tooth.

Even though I follow a ketogenic diet, desserts play a very important role.

Now, I know I shouldn’t play favorites, but a few takes the top tier. These include brownies, chocolate chip cookies, and, of course, cheesecake.

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

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.

Frequently Asked Questions

Can I eat Philadelphia cream cheese on keto?

Full fat cream cheeses, including the Philadelphia brand, are all suitable on 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.

What can I substitute for sugar in cheesecake?

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.

How many carbs are in a low carb cheesecake?

Each slice of cheesecake in this recipe has just 3 grams of net carbs.

How many carbs are in a cheesecake without a crust?

If you make this cheesecake without the cookie crust, there are just 1.5 grams of net carbs per slice.

What to serve with this dessert?

Take your cheesecake up a notch by serving it with some keto ice cream, whipped cream, a drizzle of sugar free chocolate syrup or a light dusting of keto powdered sugar.

For the cheesecake filling

  • 2 cups cream cheese softened and room temperature

  • 3 large eggs room temperature
  • 3/4 cup superfine sugar substitute I used erythritol ** See notes

  • Preheat the oven to 160C/325F. Line a 9-inch springform pan with parchment paper or tin foil and set aside.

* I used crushed keto peanut butter cookies. Almond butter cookies will work, or you may prefer to make a keto graham cracker crust.
** Superfine sugar substitute has a texture halfway between standard sugar and powdered (confectioners’) sugar. I simply blend erythritol until it achieves that texture.

  1. Hello! I appreciate this website and your recipes so much!

    I’d like to make this cheesecake with the keto graham cracker crust, and need to make sure I purchase enough of the ingredients. Do you know approximately how many cups of cookie crumbs one batch of your keto shortbread cookies yield?


  2. Really wanting to try this as an alternative for Christmas, wife is not convinced. If I were to half the recipe, do you believe it would approximately fit in one of the smaller springform pans? Would like to make a test run to prove it out to her.

    Mr. Big Man Can I make mini cheesecake bombs with this recipe? I’m going to try it this weekend! Thanks so much I will try all your keto recipes Let you know how I made out

  4. 5 stars
    This recipe was so delicious and easy to follow. Slice it into wedges wrapped with paper and put in the freezer and I take one portion out for my dinner snack.

  5. I don’t understand how you say it is sugar-free when you use caster sugar. Caster sugar is sugar. Am I missing something?

  6. Hi Arman. Thank you for the recipe <3
    I’d like to incorporate some sugar free pudding mix into this. How should I go about doing that?
    *I’ll be sure to rate it after I make it 🙂

    I tried this recipe and it is sooooo good. I garnished with fresh strawberries and keto whipped cream. It takes so much like the real deal but only 3 net carbs!!!

    I eat about 95% clean (I indulge in one or two cheat meals on the weekends) and I’ve wanted to make cheesecake but most recipes call for things that I don’t have on hand and I’m not used to cooking/baking with. I was so excited to find this simple clean cheesecake recipe! I made it today and I added two fresh mangos from my tree to the mixture and I used maple sugar (maple syrup turned into a granulated form) as the sweeter. For the crust I combined coconut oil, maple sugar, almond flour and unsweetened coconut flakes and it turned out great. This cheesecake was AMAZING! My whole family loved it. Even my very picky son who doesn’t eat clean. Thank you for sharing this!!

    I’m in Junior High and wanted to make a recipe my parents could eat but me and my sister could also enjoy. I really love cheesecake so I kinda googled a recipe and this one had a good rating. I made the cheesecake, there was some trial and error in the crust but eventually it came out and it was pretty good! Think it might be over baked though since the texture’s weird, or maybe it’s because I accidentally use granulated (fake) sugar instead of superfine (also fake) sugar? All and all a good recipe though.

    (Put a compote and fresh strawberries on top, definitely good with the fruit!)

    First time I tried it I wasn’t a fan of it. It might have been the carmel sauce I used. Wheb I tried it again with frozen blueberries it was delicious and I loved it!
