- ½ stick soft butter (2 oz / 57 g)
- ½ cup low-carb sweetener (Swerve Granulated or Lakanto Classic)
- 4 large eggs (cold; add one more egg if omitting baking powder)
- 1 cup whole milk ricotta cheese (cold, 250 g)
- 1 ½ tablespoons fresh lemon juice
- 1 teaspoon lemon zest (zest of one lemon)
- 1 teaspoon vanilla extract
Dry Ingredients:
- 1 cup almond flour (whisked before measuring)
- 4 tablespoons coconut flour* (whisked before measuring)
- 2 teaspoons baking powder** (see directions for version without baking powder)
- ¼ teaspoon salt
Preparation
- Preheat Oven:
Preheat to 325°F (160°C). Line the bottom of an 8-inch round cake pan with parchment paper. Grease or butter the pan, then place the parchment. - Prepare Dry Ingredients:
Whisk together almond flour, coconut flour, baking powder, and salt in a small bowl to remove any lumps.
Method (With Baking Powder):
- Cream Butter and Sweetener:
In a mixing bowl, cream the butter, vanilla extract, and sweetener until smooth. - Incorporate Eggs and Ricotta:
Beat in one egg until light and fluffy. Add the ricotta, lemon zest, and lemon juice, mixing until fully combined. - Combine Wet and Dry Ingredients:
Gradually mix ⅓ of the dry ingredients into the batter. Add an egg and mix. Repeat this process until all eggs and dry ingredients are fully incorporated. - Bake:
Spread the batter evenly into the prepared pan using an offset spatula. Bake for 50 minutes or until a toothpick inserted into the center comes out clean. - Cool:
Let the cake cool in the pan for 15-20 minutes. Run a knife around the edges, then flip it onto a cooling rack. Cool completely.
Method (Without Baking Powder):
- Separate and Whip Eggs:
Separate the 4 eggs, placing the whites in a medium bowl. Beat until soft peaks form. - Cream Butter and Yolks:
Cream the butter, sweetener, and vanilla extract. Add egg yolks and beat until fluffy. Mix in ricotta, the whole egg, lemon zest, and lemon juice. - Fold in Dry Ingredients:
Gradually mix in the dry ingredients until well combined. - Incorporate Egg Whites:
Fold the whipped egg whites into the batter in thirds. The batter will be thick. - Bake:
Spread evenly into the prepared pan. Bake for 50 minutes or until a toothpick comes out clean. - Cool:
Cool as directed above.
