Ingredients
Dry Ingredients
- 1 1/2 cups almond flour (or another low-carb flour alternative)
- 1 teaspoon baking powder
- 1/4 teaspoon salt
Wet Ingredients
- 3 large eggs
- 1 cup ricotta cheese (full-fat or part-skim, both work)
- 1/3 cup granulated sugar substitute (such as erythritol, stevia blend, or similar)
- 1/4 cup unsalted butter, melted
- 2 tablespoons freshly squeezed lemon juice
- Zest of 1 lemon
- 1 teaspoon vanilla extract
Optional Lemon Glaze
- 1/2 cup powdered sugar substitute
- 1 tablespoon fresh lemon juice
Instructions
1. Preheat and Prepare the Pan
- Preheat the oven to 350°F (175°C).
- Grease an 8-inch round cake pan and line the bottom with parchment paper to prevent sticking.
2. Combine the Dry Ingredients
- In a medium mixing bowl, whisk together the almond flour, baking powder, and salt.
- Set aside.
3. Prepare the Wet Mixture
- In a large bowl, beat the eggs until they are light and slightly frothy.
- Add the ricotta cheese, granulated sugar substitute, melted butter, lemon juice, lemon zest, and vanilla extract.
- Mix until the batter is smooth, creamy, and well combined.
4. Bring the Batter Together
- Gradually add the dry ingredients to the wet mixture.
- Gently fold until everything is just combined. Do not overmix, as this can affect the cake’s texture.
5. Bake
- Pour the batter into the prepared cake pan and smooth the top.
- Bake for 30–40 minutes, or until the top is lightly golden and a toothpick inserted into the center comes out clean or with just a few moist crumbs.
6. Cool the Cake
- Allow the cake to cool in the pan for about 10 minutes.
- Carefully remove it from the pan and transfer to a wire rack to cool completely.
7. Add the Optional Lemon Glaze
- In a small bowl, whisk the powdered sugar substitute with the lemon juice until smooth and pourable.
- Once the cake has cooled, drizzle the glaze over the top for an extra burst of lemon flavor.

Tips for the Best Lemon Ricotta Cake
- Use Fresh Lemon Juice: Freshly squeezed lemon juice gives a brighter, cleaner flavor than bottled juice.
- Room Temperature Ingredients: Let the eggs, ricotta, and butter come to room temperature before mixing. This helps create a smoother batter and an even texture.
- Adjust Sweetness to Taste: Different sugar substitutes vary in sweetness. Start with the suggested amount and adjust slightly if you prefer a sweeter or less sweet cake.
