Diabetic-Friendly Lemon Ricotta Cake (Low Carb)
A moist, lightly sweet lemon ricotta cake made with almond flour and coconut flour. It’s a simple, bakery-style dessert that fits a low-carb lifestyle and is suitable for many people looking for diabetic-friendly recipes.

Ingredients
- 2 oz (57 g) soft butter (½ stick)
- ½ cup low-carb sweetener (such as Swerve Granulated or Lakanto Classic)
- 4 large eggs, cold
- Use 1 extra egg if you’re making the version without baking powder.
- 1 cup (250 g) whole milk ricotta, cold
- 1 ½ tablespoons fresh lemon juice
- 1 teaspoon lemon zest (zest of 1 lemon)
- 1 teaspoon vanilla extract
- 1 cup almond flour (whisk before measuring)
- 4 tablespoons coconut flour (whisk before measuring)
- 2 teaspoons baking powder (see note above for no-baking-powder option)
- ¼ teaspoon salt
Preparation
- Preheat the oven to 325°F (163°C).
- Cut parchment paper to fit the bottom of an 8 x 2-inch round cake pan.
- Grease the pan with butter or spray, then place the parchment on the bottom.
- In a small bowl, add all dry ingredients and whisk well to remove lumps.
Method
- In a mixing bowl, cream the butter, vanilla, and sweetener until smooth and fully combined.
- Add 1 egg and beat until the mixture becomes lighter and fluffy.
- Add the ricotta, lemon zest, and lemon juice, then mix until evenly blended.
- Add the dry ingredients in three portions:
- Mix in ⅓ of the dry ingredients
- Add 1 egg, then mix again
- Repeat this process until everything is incorporated, ending with the final egg
Bake and Cool
- Gently spread the batter into the prepared pan using an offset spatula.
- Bake for about 50 minutes, or until a toothpick inserted in the center comes out clean.
- Remove from the oven and cool in the pan for 15–20 minutes.
- Run a knife around the edges to loosen the cake, then turn it out onto a rack to cool completely.
Storage and Serving
- Wrap leftovers tightly in cling film.
- Keep at room temperature for up to 3 days (avoid this if your kitchen is hot or humid), or refrigerate for longer storage.
- If chilled, warm slightly before serving for the best texture.
- Makes 9 servings, approximately 3.5 net carbs per slice.
