Ingredients

Scale
  • 2 ½ cups (315g) all-purpose flour
  • 1 ½ cups (300g) granulated sugar
  • 1 teaspoon baking soda
  • 1 teaspoon fine salt
  • 1 tablespoon unsweetened cocoa powder
  • 1 ½ cups (360ml) buttermilk, room temperature (or milk + 1 tbsp vinegar)
  • 1 ½ cups (360ml) vegetable oil
  • 2 large eggs, room temperature
  • 2 tablespoons red food coloring (gel preferred)
  • 1 teaspoon pure vanilla extract
  • 1 teaspoon white vinegar
  • 16 oz (450g) cream cheese, softened
  • ½ cup (115g) unsalted butter, softened
  • 4 cups (480g) powdered sugar, sifted
  • 1 teaspoon pure vanilla extract (for frosting)
  • Pinch of salt (for frosting)
  • Fresh blueberries (for blue section of the flag)
  • Strawberries or raspberries, sliced (for red stripes)

Instructions

  1. Preheat oven to 350°F (175°C). Grease and lightly flour two 9-inch round cake pans and line bottoms with parchment paper.
  2. In a large bowl, sift together flour, sugar, baking soda, salt, and cocoa powder. Whisk to combine.
  3. In a separate bowl, whisk buttermilk, vegetable oil, eggs, red food coloring, vanilla extract, and white vinegar until smooth.
  4. Gradually add wet ingredients to dry ingredients, mixing gently until just combined. Batter should be smooth and vibrant red.
  5. Divide batter evenly between prepared pans and smooth tops. Bake for 30–35 minutes or until a toothpick inserted comes out clean. Rotate pans halfway through baking.
  6. Cool cakes in pans for 10 minutes, then invert onto cooling racks and remove parchment. Cool completely before frosting.
  7. Beat cream cheese and butter until smooth and creamy. Gradually add powdered sugar, beating well after each addition. Stir in vanilla and salt. Frosting should be fluffy but firm.
  8. Place one cake layer on serving plate. Spread a generous layer of frosting on top. Add second layer and apply a thin crumb coat over entire cake. Chill for 20 minutes.
  9. Decorate cake with remaining frosting: frost a rectangular area in top-left corner for blue field and place blueberries. Use sliced strawberries or raspberries to create red stripes alternating with frosting stripes.
  10. Refrigerate cake for at least 30 minutes before serving. Bring to room temperature 15 minutes before cutting.

Notes

Sift dry ingredients to avoid lumps. Avoid overmixing batter to keep cake fluffy. Use room temperature cream cheese and butter for smooth frosting. Chill cake between frosting layers for clean lines. Rinse and dry berries thoroughly before decorating. Store cake refrigerated and bring to room temperature before serving.
