Ingredients
Scale
- 2 cups almond flour
- 1/4 cup coconut flour
- 1/4 cup granulated erythritol
- 1 tablespoon poppy seeds
- 1 teaspoon baking powder
- 1/2 teaspoon baking soda
- 1/2 teaspoon salt
- 3 large eggs
- 1/2 cup unsweetened almond milk
- 1/4 cup melted coconut oil
- 1 tablespoon lemon juice
- 1 tablespoon lemon zest
- For the Berry Frosting:
- 1/2 cup unsalted butter, softened
- 1 cup powdered erythritol
- 1/4 cup fresh blackberries
- 1 teaspoon vanilla extract
- 1–2 tablespoons heavy cream (adjust for texture)
Instructions
- Preheat your oven to 350°F (175°C) and prepare an 8-inch round cake pan by greasing it and lining the bottom with parchment paper.
- In a mixing bowl, combine the almond flour, coconut flour, erythritol, poppy seeds, baking powder, baking soda, and salt, whisking them together until well blended.
- In a separate bowl, crack the eggs and whisk them before adding the almond milk, melted coconut oil, lemon juice, and lemon zest. Stir this mixture until it is thoroughly combined.
- Pour the wet ingredients into the dry mixture, gently folding them together until just combined—be careful not to overmix.
- Transfer the batter into the prepared cake pan, leveling the surface with a spatula.
- Bake for approximately 25-30 minutes, or until a toothpick inserted in the center comes out clean.
- Let the cake cool in the pan for about 10 minutes before moving it to a wire rack to cool completely.
- While the cake cools, prepare the berry frosting by beating the softened butter until fluffy.
- Gradually add the powdered erythritol, fresh blackberries, and vanilla extract, mixing until the frosting is smooth.
- If the consistency is too thick, incorporate heavy cream one tablespoon at a time until you reach your desired texture.
- Once the cake has cooled down, generously spread the berry frosting over the top.
- Cut into slices and enjoy!
Notes
- Ensure the cake is completely cool before frosting to prevent melting.
- Adjust the amount of heavy cream in the frosting based on your preferred texture.
