This keto chocolate cheesecake is perfect for Thanksgiving, Christmas, a family gathering or any special celebration. Decadently chocolatey, creamy and utterly delicious, this recipe is gluten-free and so easy to make.

I've been serving this cake at several dinner parties now and it always goes down a treat, whether people are following a keto diet or not!
It is creamy, smooth dark chocolate indulgence in every mouthful. In fact, it is hard to believe it's sugar free and low carb.
Even though this sugar free chocolate cheesecake looks impressive, it is very easy to make. The total hands-on time is only 20 minutes.
All you need to do is plan for the time it needs to chill, which is best done overnight.
Ingredients
Here are the ingredients you need to make a keto chocolate cheesecake:
- Almond flour - Both fine almond flour or ground almonds work.
- Butter
- Sweetener - It's important to use powdered sweetener for the filling to ensure it is silky-smooth.
- Sugar-free or dark chocolate
- Mascarpone and cream cheese - I used a mix, but you can also use either one or the other.
- Vanilla extract
- Heavy whipping cream
- A pinch of sea salt
Instructions
This section contains step-by-step instructions and photos that show how to make this recipe. See the recipe card for full information on ingredients and quantities.

First, let's make the almond flour crust.
Step 1: Mix the almond flour, sweetener and butter in a bowl to form a crumbly dough.

Step 2: Press the mixture into a loose bottom cake tin or springform pan and bake it in the oven until until slightly golden.
Now onto the chocolate cheesecake filling!

Step 3: Place the sugar free chocolate chips in a heatproof bowl over a pan of hot water. Simmer until melted, then let cool.

Step 4: Whip the mascarpone, cream cheese, heavy cream, sweetener, vanilla and a pinch of salt in a large mixing bowl using an electric hand mixer until thick.

Step 5: Slowly pour in the melted chocolate and fold in with a spatula to combine.
Step 6: Taste, and adjust the sweetness if necessary. I don't have much of a sweet tooth, so feel free to increase it to taste.

Step 7: Spoon the chocolate mix onto the crust and smooth the top with a spatula. Then chill in the fridge until set.

Last, let's make the low carb chocolate frosting.
Step 8: Heat the cream and butter (or use coconut oil) on a low heat. Turn off the heat and add the chopped dark chocolate or sugar free dark chocolate chips and allow to stand until they are melted. Stir briskly with a balloon whisk until glossy and smooth.

Step 9: Spread the ganache over the top of the keto chocolate cheesecake and top with grated chocolate. Serve straight away or cool in the fridge if you prefer a set ganache.
Top Tips
The right temperature is key! Use ROOM TEMPERATURE mascarpone and cream cheese and let the melted chocolate COOL a little from hot to warm before you add it to the mix. If the temperature difference is too great the chocolate can seize and become lumpy.
Don't over-beat: If you use an electric whisk, put it on a low setting and don’t over-beat the chocolate mix or it will go stiff. Should your mix become too firm when you beat it together, simply add a little more heavy cream to loosen.
Variations
To change up the flavor, consider adding the following to the filling mixture:
- Coffee: 1-2 shots of strong espresso
- Peppermint: 1 teaspoon of mint extract
- Orange: 2 teaspoons of orange extract
Recipe FAQs
Make sure you're using powdered sweetener, especially when using erythritol. This ensures the filling is nice and smooth.
I used an erythritol monk fruit sweetener blend. Lakanto is my go to brand (If you use my code SUGARFREE at checkout you get a 15% discount!). Allulose or Bocha Sweet will work as well.
You can also use xylitol - just be aware that it is toxic to dogs. Also possible would be stevia glycerite. I would go for 20 drops and take it from there.
I used a chocolate with 85% cocoa solids in this recipe. A 90% dark chocolate would be even lower in carbs.
If you prefer generous, larger slices (16 per cake) and still want a low carb count, use sugar free chocolate or unsweetened chocolate.
Note - If you use unsweetened chocolate, you'll need to use around ¾ cup - 1 cup of powdered erythritol to sweeten the filling.
I do not recommend it as this would change the texture of the filling.
No, it's not necessary! You can omit the oven and make this a no bake keto cheesecake.
Simply use the coconut flour crust in my strawberry mascarpone tart recipe. I'm recommending this recipe because you cannot replace almond flour with coconut flour 1:1.
Yes. You can halve the ingredients and use a small springform pan.

Topping ideas
We loved the chocolate ganache topping. To mix it up, here are more topping ideas:
- Chopped nuts such as walnuts, hazelnuts or pecans
- Berries
- Raspberry sauce
- Shredded coconut
- A dusting of cocoa powder
- crumbled keto chocolate chip cookies or ginger snaps.
- Keto caramel sauce
- Sugar free chocolate sauce
Storage
Refrigerator: Store this cheesecake in the fridge for up to 4 days.
Freezer: All keto cheesecakes freeze well. Slice and store in the freezer for up to 3 months.
Make sure you defrost the slices in the fridge overnight.
I have calculated 16 slices for this cake because it is filling. You could easily serve it to 20 people, especially if you're adding keto whipped cream on the side or a scoop of sugar free vanilla ice cream. (I've given the nutrition for both).

Are you able to make it without sea salt?
Katrin Nürnberger
Of course, you don't have to add any salt to the cake.
Katrin Nürnberger
Of course! since the are already sweet, adjust the additional sweetener in the recipe.
kirsten carvajal
Hi! Do you have a version of this cheesecake without the chocolate?
Thanks!
Katrin Nürnberger
Yes! I love this sugar free Cheesecake recipe.
MaryJo
Can I use extra cream cheese for the Mascarpone ❓
Katrin Nürnberger
Mascarpone is slightly higher in fat than cream cheese (35% versus 28% per 100g), which means it's firmer. But as you're also adding the melted chocolate, I think using just cream cheese should work. Make sure the cake is truly, fully cooled before slicing.
Barbara T
I want to make a small cheesecake in a springform pan and then the rest in ramekins. Do you think that the ramekins would work out OK?
Katrin Nürnberger
Yes, that should work. Make sure you grease them well so you can release the cake.
Rach MacGregor
Thank you for this great recipe! I made it last night with some slight adjustments ( I added cocoa to the base and didn’t do the ganache) it was amazing!!!
Barry
That sounds interesting. How much cocoa did you add?
William
Delish. A little different than baked cheesecake, but extremely rich and delicious. I added about 1/4 cup of greek yogurt, which I usually add to baked cheesecake. I didn't have heavy cream so I added half & half. didn't matter, It was perfect. I also added cocoa to the batter with Lily's chips and just melted chips w/coconut oul for the topping. I'll definately make it again. thanks.
Nina
2nd time I've made this. Unsuspecting family can't get enough of it.

Can this be made crustless and if so, how does it affect the nutritional breakdown?
