Ingredients
Almond flour – This is used to make the keto cheesecake crust. You can also see the recipe card for directions on adding coconut flour and flaxseeds as well.
Melted butter – You’ll use a little bit of butter to form the base of the cheesecake crust.
Cream cheese – This is used to make the creamy filling of this great recipe.
Joy Filled Eats Sweetener – The perfect low carb sweetener.
Lemon extract – Using lemon extract adds a delicious hint of lemon.
Salt – For flavor.
Eggs – For texture.
Sour cream – Used to make the topping.
Berries – This can be optional, but any lemon lover will tell you that lemon flavor and berries are a dessert dream come true.
How to Make Keto Lemon Cheesecake
Step One: Mix the melted butter and the almond flour, then press the mixture into the bottom of a deep dish pie plate. If you prefer to use a springform pan you can.
Step Two: Put the pie plate into the oven and bake for 10 minutes or until slightly golden. Let the crust cool for 10 minutes.
Step Three: To make the filling, mix the cream cheese with a hand mixer until fluffy. Add the sweetener, lemon extract, and salt. Mix until you have a smooth and creamy texture.
Step Four: Add the eggs one at a time and mix after each one. Pour the cheesecake filling into the cooled, baked crust.
Step Five: Put the cheesecake into the oven and bake for 20 minutes. Reduce the oven temperature to 200 degrees, then bake the cheesecake for another 20 minutes or until the cheesecake is set. Let the cheesecake cool to room temperature.
Step Six: To make the sour cream topping, mix the sour cream and sweetener. Spread the mixture out over the top of the cooled cheesecake and then place in the fridge to cheese for at least 2 hours. (or until it is cold) Sprinkle with berries and serve.
Variations
Low Carb Cheesecake Crust – You can make a flour blend for the crust instead of using just almond flour. The flour blend is equal parts of coconut flour, ground golden flaxseeds, and almond flour. You gain some nutrients from the mix, which is a nice bonus.
Substitutions
Lemon zest – Instead of using lemon extract, you can opt for lemon zest from regular lemons. You could also use fresh lemon juice.
Toppings – Lemon desserts can easily be topped with other fun ingredients. To make this creamy lemon cheesecake look super fancy, you can top it with fresh lemon slices. You can also add a bit of gluten free lemon curd, or an array of fresh berries.
Make mini cheesecakes – If you want to make individual cheesecakes, you can add the mixture to different ramekin sizes and serve these at dinner parties. Keto lemon cheesecake cups are the perfect party treat!

Other Cheesecake Toppings
Looking for other fruit to pair with your lemon cheesecake? Here are some tasty pairings.
- Raspberries
- Strawberries
- Blackberries
- Mixed Fruit
- Whipped Cream – even with the sour cream topping a little whipped cream is always a treat!
No matter how you serve up this keto lemon cheesecake, it is sure to be a delightful experience. Enjoy.
Storage
Once you have allowed your cheesecake to cool it goes back into the fridge. Cover it with plastic wrap or store it in an airtight container. While some prefer the taste of room temperature cheesecake, it is important to always store cheesecake in the refrigerator. The cream cheese and sour cream can go bad if left out on the counter.
What I recommend doing for this cheesecake is allowing the cheesecake to cool and then freezing it. Leave the sour cream and blueberries off of it, as the sour cream can separate once thawing, and the blueberries will become mushy. Then, when you are ready to serve, just thaw in the fridge the night before.
Then create your sour cream topping and pour over the top, and top with fresh blueberries than serve.
Common Questions
You want to make sure when you are mixing your batter it is nice and smooth. If you find the batter is lumpy, you will have a lumpy cheesecake. Make sure you are using softened cream cheese so that it can blend well with the other ingredients. Use room temperature ingredients, so it doesn’t chill the cream cheese when blending.
What I like to do is gently shake the cheesecake in the oven to see if it is done. You don’t want to see the cheesecake jiggle when you shake it back and forth. The center needs to be almost set, with just a small circle in the center that jiggles or none at all. It will set up more as it cools.
If your cheesecake splits, it is okay; you have the sour cream topping to hide it. One reason cheesecakes split is due to overmixing the batter. It will create air bubbles that need to be released in the cooking process, resulting in cracks.

Absolutely fabulous, easy, creamy and tastes fantastic. Love the Almond flour crust!!
I love this recipe; however, I used 1 1/2 cups of almond flour to make a crust large enough to cover the bottom of my pie pan. The suggestion of 1/2 cup was barely enough to cover the pan.
We all LOVE this Keto Lemon Cheesecake ❣️I added 2T. Sweetner xtra. 👏👏
Thank you. It’s easy to make too. ❤️
