Ingredients

Scale
  • 2 ½ cups almond flour
  • 1 teaspoon baking powder
  • ¼ teaspoon salt
  • 4 large eggs, room temperature
  • ¾ cup powdered erythritol
  • ½ cup unsalted butter, melted and slightly cooled
  • 1 teaspoon vanilla extract
  • ¼ cup unsweetened almond milk
  • 8 oz cream cheese, softened
  • ½ cup heavy whipping cream
  • ¼ cup powdered erythritol (for frosting)
  • 1 teaspoon vanilla extract (for frosting)
  • 1 cup fresh strawberries, sliced
  • 1 cup fresh blueberries
  • Optional: mint leaves for garnish

Instructions

  1. Preheat the oven to 350°F (175°C). Grease a 9×13-inch pan lightly with butter or line it with parchment paper.
  2. In a large bowl, whisk together almond flour, baking powder, and salt until well combined.
  3. In a separate bowl, beat the eggs and powdered erythritol with an electric mixer until pale and slightly fluffy, about 2-3 minutes.
  4. Slowly pour melted butter, vanilla extract, and almond milk into the egg mixture, mixing gently to combine.
  5. Fold the dry ingredients into the wet mixture using a rubber spatula. Add extra almond milk if batter feels too thick.
  6. Pour batter into the prepared pan, spread evenly, and tap the pan lightly to release air bubbles.
  7. Bake for 25-30 minutes or until the top is golden and a toothpick inserted in the center comes out clean.
  8. Cool completely on a wire rack before frosting.
  9. Beat softened cream cheese, heavy cream, powdered erythritol, and vanilla extract until fluffy and smooth.
  10. Spread an even layer of frosting over the cooled cake.
  11. Arrange sliced strawberries in horizontal stripes across two-thirds of the cake, leaving a square in the upper left corner for blueberries.
  12. Fill the square with fresh blueberries to mimic the flag’s stars area.
  13. Refrigerate the cake for at least 30 minutes to set the frosting and let flavors marry.

Notes

Use room-temperature eggs for better texture. Don’t skip baking powder for lift. Watch the oven closely as almond flour browns quickly; tent with foil if needed. Chill frosting ingredients for better whipping. Arrange berries just before serving to keep fresh. For dairy-free, substitute butter with coconut oil and heavy cream with coconut cream. Frozen berries can be used after thawing and draining.
