Ingredients

Scale
  • 2 ½ cups all-purpose flour (312 g)
  • 1 ½ cups granulated sugar (300 g)
  • 2 tablespoons unsweetened cocoa powder
  • 1 teaspoon baking soda
  • ½ teaspoon salt
  • 1 cup buttermilk (240 ml), room temperature (or 1 cup milk + 1 tbsp vinegar)
  • 1 cup vegetable oil (240 ml)
  • 2 large eggs, room temperature
  • 2 tablespoons red food coloring (liquid or gel)
  • 1 teaspoon vanilla extract
  • 1 teaspoon white vinegar
  • 8 oz cream cheese (225 g), softened
  • ½ cup unsalted butter (115 g), softened
  • 4 cups powdered sugar (480 g), sifted
  • 1 teaspoon vanilla extract
  • Pinch of salt
  • 1 ½ cups fresh strawberries, hulled and sliced
  • 1 cup fresh blueberries
  • 1 cup fresh raspberries
  • 1 cup fresh blackberries

Instructions

  1. Preheat oven to 350°F (175°C). Grease two 9-inch round cake pans and dust with flour or line with parchment paper.
  2. In a medium bowl, sift together flour, sugar, cocoa powder, baking soda, and salt.
  3. In a large bowl, whisk together buttermilk, vegetable oil, eggs, red food coloring, vanilla extract, and white vinegar until combined.
  4. Gradually add dry ingredients to wet ingredients, stirring gently with a rubber spatula until just combined.
  5. Divide batter evenly between prepared pans. Tap pans gently to release air bubbles.
  6. Bake for 30-35 minutes or until a toothpick inserted in the center comes out clean.
  7. Cool cakes in pans for 15 minutes, then invert onto cooling racks to cool completely.
  8. Beat cream cheese and butter until smooth. Gradually add powdered sugar, beating well after each addition. Stir in vanilla extract and salt.
  9. Place one cake layer on serving plate. Spread about 1 cup frosting evenly over the top.
  10. Arrange fresh blueberries in a neat rectangle on one side to represent stars.
  11. Arrange sliced strawberries in rows next to blueberries for stripes, alternating with lines of cream cheese frosting.
  12. Repeat with raspberries and blackberries to complete the flag pattern.
  13. Spread remaining frosting around sides and top of cake. Decorate with extra berries.
  14. Refrigerate for at least 30 minutes before serving. Let sit at room temperature 15 minutes before slicing.

Notes

Use room temperature ingredients for better texture. Do not overmix batter to keep cake tender. Chill frosting if too soft before assembling. Cool cake layers completely before frosting to avoid melting. Pat berries dry to prevent soggy frosting. Cake can be made ahead by baking layers a day in advance and assembling before serving.
