Instructions
- Step 1: Preheat the oven to 350°F (175°C) and grease a 9-inch round cake pan with butter.
- Step 2: In a medium bowl, whisk together 1 1/2 cups almond flour, 1/4 cup coconut flour, 1 tsp baking powder, and 1/4 tsp salt until well combined.
- Step 3: In a large bowl, beat 4 large eggs with 3/4 cup erythritol using an electric mixer on high speed for 3-4 minutes until pale and fluffy.
- Step 4: Slowly fold the dry ingredients into the egg mixture, then gently stir in 1/2 cup melted unsalted butter and 1 tsp vanilla extract until the batter is smooth.
- Step 5: Pour the batter into the prepared cake pan and bake for 25-30 minutes until a toothpick inserted in the center comes out clean; let the cake cool completely.
- Step 6: Meanwhile, whip 1 cup heavy cream until stiff peaks form.
- Step 7: Once cooled, slice the cake horizontally into two layers, spread half the whipped cream on the bottom layer, scatter 1/2 cup fresh blueberries over the cream, then place the top layer and repeat with remaining cream and blueberries.
- Step 8: Optionally, dust the top with 1 tbsp powdered erythritol before serving.
