Instructions

  1. Step 1: Preheat the oven to 350°F (175°C). In a mixing bowl, combine 1 1/2 cups almond flour, 1/2 cup erythritol sweetener, and 1 tsp baking powder, whisking until evenly mixed.
  2. Step 2: In a separate bowl, beat 4 large eggs with 1/4 cup unsweetened almond milk, 1 tbsp vanilla extract, and 2 tbsp softened unsalted butter until smooth and fluffy.
  3. Step 3: Gently fold the dry ingredients into the wet ingredients until just combined, avoiding overmixing to keep the batter light.
  4. Step 4: Pour the batter evenly into two 8-inch round cake pans lined with parchment paper. Bake for 25-30 minutes until a toothpick inserted in the center comes out clean. Let cool completely.
  5. Step 5: While cooling, whip 1 cup heavy whipping cream with 2 tbsp powdered erythritol until stiff peaks form.
  6. Step 6: To assemble, place one cake layer on a serving plate, spread half the whipped cream evenly, then scatter 1/2 cup fresh raspberries over the cream.
  7. Step 7: Top with the second cake layer, spread the remaining whipped cream over the top, and garnish with the remaining 1/2 cup fresh raspberries for a fresh finish.
