  • 8-inch or 9-inch spring form pan


For the crust:

  • 1 1/2 cup almond flour
  • 2 tablespoons baking stevia (or use Swerve Granular Sweetener)
  • 1/2 teaspoon vanilla extract
  • 4 tablespoons butter melted

For the cheesecake filling:

  • 24 ounces full fat cream cheese at room temperature
  • 1/2 cup baking stevia (or use Swerve Granular Sweetener)
  • 6 tablespoons sour cream (use full fat)
  • 2 eggs
  • 2 egg yolks
  • 1 teaspoon vanilla extract
  • 2 teaspoons lemon juice
  • zest of 1 lemon
  • 1/4 teaspoon salt


  • 1 1/2 teaspoons lemon juice
  • 7 tablespoons sour cream (use full fat)
  • 5 teaspoons baking stevia (or use Swerve Granular Sweetener)


For the crust:

  • Preheat your oven to 350 degrees Fahrenheit.
  • Add the finely ground almond flour to a bowl along with the stevia, vanilla and melted butter.
  • Stir everything together well and press the mixture into the bottom of a 8-inch or 9-inch spring form pan (if using an 8-inch pan, the mixture will go up the sides a little bit).
  • Bake for 10 minutes and then remove it from the oven to let it cool.

For the cheesecake filling:

  • Turn your oven down from 350 degrees to 325 degrees.
  • Mix the cream cheese and baking stevia together with a hand mixer or stand mixer (fitted with the paddle attachment) until creamy and smooth. Be sure your cream cheese is at room temperature.
  • Add the sour cream and mix well to combine.
  • Add the eggs and egg yolks one at a time, just until incorporated. Don't over-mix when adding the eggs as this can create air bubbles in the batter which will cause the cheesecake to crack.
  • Mix in the vanilla, lemon juice and zest, and salt, just until combined. Scrape down the sides of the bowl to make sure everything is incorporated.
  • Pour the cheesecake filling into the prepared (and cooled) crust and tap it on the counter gently so any air bubbles rise to the surface.
  • Bake at 325 degrees for 1 hour and 20 minutes if using an 8-inch pan (bake for one hour and 5 minutes if using a 9-inch pan). After baking for the recommended time the cheesecake should be set around the edges with a slight jiggle in the centre.

For the topping:

  • Right after removing the cheesecake from the oven, mix together the lemon juice, sour cream, and baking stevia in a bowl with a whisk until very smooth.
  • Spread the sour cream mixture over the top of the cheesecake while it's hot using an offset spatula.
  • Let the cheesecake cool to room temperature in the pan and then place it in the fridge to chill for 6 hours or overnight.
  • Slice and serve after chilling with some fresh berries.


It's important to use a sweetener in this recipe that can be substituted for sugar with a 1:1 ratio. Some low-carb sweeteners are almost twice as sweet as sugar and require only half the amount of sweetener to be added to a recipe. We like baking stevia or Swerve Granular Sweetener.
This recipe can be made in an 8-inch round spring form pan OR in a 9-inch round spring form pan. If using an 8-inch pan, bake for 1 hr 20 mins. If using a 9-inch pan, bake for 1 hr 5 mins.
