This easy no bake sugar free cheesecake has a silky-smooth, creamy filling and a buttery almond flour crust. It’s a low carb cheesecake recipe the whole family is going to love – in fact, you’d never guess it’s sugar free, gluten free and keto. My kids both asked for seconds!
My friends, this no bake cheesecake is so easy and so delicious at the same time that I think it deserves a place in the hall of fame for sugar free desserts!
I have quite a few sugar free cheesecake recipes on my website already. Amongst my favourites for summer are this sugar free strawberry cheesecake and this low carb lemon cheesecake. In winter I’ll crave this epic keto chocolate cheesecake and of course my keto cheesecake brownies.
I felt I needed to include a classic no bake low carb cheesecake in my repertoire. One that tastes wonderful all on its own, but can be customised with different toppings, from fruit and berries like I chose to caramel or sugar free chocolate (see a list of ideas at the end of the post!).
That’s how this low carb cheesecake recipe was born 😉
How many carbs in sugar free cheesecake?
A slice of this no bake sugar free cheesecake without topping has only 2.8 grams of net carbs. If you include the optional berries and additional whipped cream on top, this increases to 3.8 grams net carbs. So in case you are wondering “is sugar free cheesecake keto?” – the answer is a resounding YES.
You see, it’s actually really easy to make a low carb gluten free cheesecake recipe. You only have to change two ingredients – the flour and the sugar – and replace them with nut flour and a sweetener such as erythritol.
The rest of the ingredients are already naturally low in carbs and sugar. Cream cheese and double cream (that’s heavy cream in the US), which you need for the filling, are regulars in keto desserts!
Baked vs no bake low carb cheesecake
I love classic baked New York style cheesecakes. But admittedly they require a little more attention and care, because the top can crack easily.
First of all, you have to line the outside of your pan with foil. Then you must put your pan into a larger pan half-filled with water. Also, you must take care that you don’t over-cook it. The center should be ALMOST set, but must be still jiggly. And lastly, you should never cool it too fast. Why? Because the sudden temperature change can cause a crack in the filling at the very end. Basically, it’s a minefield for a novice baker!
This no bake sugar free cheesecake, on the other hand, is a BREEZE. No risk of cracks or sunken middles. No bake means it’s totally FAILSAFE. Easy-peasy. No waiting until the oven is hot. It’s mix, cool, enjoy!
How to make a no bake sugar free cheesecake – step by step:
1.) Get your ingredients ready! You’ll need almond flour or ground almonds, coconut flour, melted butter, powdered erythritol and a pinch of salt for the base. For the filling, measure out cream cheese or mascarpone, lemon juice, vanilla extract and heavy cream / double cream.
2.) Place all the dry base ingredients in a mixing bowl and stir to combine. Add the melted butter and mix to form a flakey crumb.
3.) Grease a 7 inch non-stick loose bottom baking tin (or a springform tin) with a little melted butter.
Then, press the base mix into the bottom and smooth with the back of the spoon to get the edges nice and neat.
4.) In a clean mixing bowl, add the cream cheese, powdered erythritol, lemon juice, vanilla and salt. Mix with an electric mixer to combine, about 1 minute. Taste and adjust the sweetness to your palate with optional liquid stevia.
In a separate bowl, whip the cream until thick (but don’t over whisk so it goes super stiff).
5.) Fold the cream through the cream cheese with a spatula to combine.
6.) Spoon the filling on top of the base and smooth the top off with a silicone spatula.
Place the sugar free cheesecake in the fridge to fully set, about 6 – 8 hours, or overnight. Alternatively, place in the freezer until set.
Tip: I left mine in the fridge overnight because I was taking the pictures the next morning. I then popped it in the freezer for 30 minutes before adding the topping and slicing. This made it very firm, but not frozen.
Low carb cheesecake topping
For the topping, add 3/4 cup heavy cream to a mixing bowl and whisk using an electric whisk until thick, but still fluid, not super stiff.
Run a sharp knife along the inside of the cake tin to release the cake before you open the springform or remove the tin.
Top with whipped cream, smoothing with a spatula for pillowy ripples and top with sliced strawberries and raspberries. Option to dust with a little powdered erythritol for prettiness.
Serve and enjoy!!
Sugar free cheesecake crust options
My low carb gluten free crust is so yummy that you won’t miss the graham crackers you’d use in a traditional cheesecake at all. However, I always get questions on how to substitute ingredients, so I have summed up all crust variations I can think of:
Sugar free cheesecake with almond flour crust
If you don’t want to use coconut flour, omit it and use 1 1/2 cup or 150 grams of almond flour in total.
Coconut flour crust
I know some of my readers are allergic to almond flour. In this case, use 1/2 cup / 60g of coconut flour to make the crust. You need less coconut flour because it absorbs more liquid than almond flour.
Use other nuts
You can replace the almond flour with other nut flours! Ground pecans or walnuts would work well. If you want to steer away from nuts altogether, you could also consider using sunflower seed meal. Replace these options 1:1 with the almond flour.
Dairy free crust
To make the crust dairy free, replace the butter with the same amount of coconut oil or ghee.
Crustless keto cheesecake
Yes, even this is an option! You actually don’t need the crust at all. If you omit it, be sure to line the bottom of the cake tin with parchment paper so you can remove the base easily.
My sugar free cheesecake base top tip
To get the base nice and firm and neat, press the crust mix into the bottom of your cake tin with your fingers. Then get the back of a spoon and smooth, paying particular attention to the edges and pressing all around the rim.
Keto cheesecake filling
It’s possible to use either cream cheese or mascarpone for the filling. Mascarpone will make the end result a little richer. The double cream / heavy cream is non-negotiable, as it helps keeping the filling firm.
The great thing about this recipe is that you don’t need to add gelatin for the cake to set. This only becomes necessary once you add additional ingredients that contain liquid, such as lemon juice or fruit.
This cheesecake is simple, and simply delicious 🙂 Incidentally, the filling all on its own would also make a fabulous keto cheesecake fluff. Simply mix, fill into individual jars, cool and enjoy!
Sugar free sweetener
In most sugar free desserts it’s fine to use granulated erythritol, such as in cakes or cookies. For any recipe that has a silky-smooth finish though we MUST use powdered erythritol.
The reason is that erythritol does not melt into liquids like regular sugar does. And who likes a grainy cheesecake filling, right?
You can use pure erythritol or an erythritol / stevia or erythritol / monkfruit mix or Swerve.
If you don’t have powdered erythritol to hand, you can powder it yourself in a coffee grinder or in a high speed blender.
You could also use xylitol or Splenda in this sugar free cheesecake recipe, which I know is still popular in the diabetic community. With Splenda you MUST measure in cups and not in weight. It’s lighter than erythritol and if you’d measure it in grams you would use WAY too much.
I don’t recommend using allulose for the filling.
Sugar Free No Bake Cheesecake Toppings
Purists will enjoy this cheesecake without toppings. I have added whipped cream and a mix of strawberries and raspberries plus some lemon zest. Here are some more topping ideas:
– Blueberries or blackberries
– melted sugar free chocolate
– raspberry coulis (mix mashed raspberries with a little powdered sweetener)
How to store sugar free cheesecake
The most important thing is to keep it cool! Store it covered in the fridge for up to 5 days. Alternatively, freeze for up to 3 months.
Ideally, freeze without toppings.
