Ingredients

Scale
  • 2 ½ cups (312g) all-purpose flour, sifted
  • 2 cups (400g) granulated sugar
  • 2 tablespoons (15g) unsweetened cocoa powder, preferably Dutch-processed
  • 1 teaspoon baking soda
  • 1 teaspoon salt
  • 1 ½ cups (360ml) buttermilk, room temperature
  • 1 cup (240ml) vegetable oil
  • 2 large eggs, room temperature
  • 1 tablespoon white vinegar
  • 2 teaspoons pure vanilla extract
  • 2 tablespoons red food coloring (gel or liquid)
  • 16 ounces (450g) cream cheese, softened
  • ½ cup (115g) unsalted butter, softened
  • 4 cups (480g) powdered sugar, sifted
  • 1 teaspoon pure vanilla extract
  • Pinch of salt

Instructions

  1. Preheat oven to 350°F (175°C). Grease and line two 9-inch cake pans with parchment paper. (5 minutes)
  2. In a large bowl, sift together flour, sugar, cocoa powder, baking soda, and salt. Whisk to combine. (5 minutes)
  3. In a separate bowl, whisk buttermilk, vegetable oil, eggs, white vinegar, vanilla extract, and red food coloring until smooth. (5 minutes)
  4. Slowly pour wet ingredients into dry ingredients, stirring gently with a spatula until just combined. Avoid overmixing. (3 minutes)
  5. Pour batter evenly into prepared pans. Smooth tops and bake for 30–35 minutes or until a toothpick comes out clean. Rotate pans halfway through. (30–35 minutes)
  6. Cool cakes in pans on wire rack for 10 minutes. Run a knife around edges, invert onto rack, peel off parchment, and cool completely. (1 hour)
  7. Beat cream cheese and butter until smooth and fluffy. Gradually add powdered sugar on low speed. Add vanilla and salt. Beat until creamy. (10 minutes)
  8. Slice each cake layer horizontally to create four thin layers. Spread frosting between layers and cover top and sides evenly. (15 minutes)
  9. Create flag design using thin strips of red velvet cake or pipe red-tinted frosting stripes; use blueberries or blue-tinted frosting for the blue field. (10 minutes)
  10. Chill assembled cake for at least 30 minutes to set frosting. Bring to room temperature before serving. (30 minutes)

Notes

Use room temperature ingredients for best results. Avoid overmixing batter to keep cake tender. Chill frosting if too soft before spreading. For gluten-free, substitute flour with almond or gluten-free flour blends. For dairy-free, use almond milk with lemon juice and dairy-free cream cheese and butter alternatives. The flag design can be personalized with seasonal fruits or colored frosting.
