Ingredients

Scale
  • 2 ½ cups (315g) all-purpose flour, sifted
  • 2 tablespoons unsweetened cocoa powder
  • 1 teaspoon baking soda
  • ½ teaspoon salt
  • 1 ¾ cups (350g) granulated sugar
  • 1 cup (240ml) vegetable oil (can substitute with melted coconut oil)
  • 2 large eggs, room temperature
  • 1 cup (240ml) buttermilk, room temperature (or 1 cup milk + 1 tbsp lemon juice as substitute)
  • 1 tablespoon white vinegar
  • 2 teaspoons vanilla extract
  • 2 tablespoons red food coloring (gel preferred)
  • 8 ounces (225g) cream cheese, softened
  • ½ cup (115g) unsalted butter, softened
  • 4 cups (480g) powdered sugar, sifted
  • 1 teaspoon vanilla extract
  • Pinch of salt

Instructions

  1. Preheat oven to 350°F (175°C). Grease and flour two 9-inch round cake pans or line with parchment paper.
  2. In a large bowl, sift together flour, cocoa powder, baking soda, and salt. Set aside.
  3. In a separate bowl, whisk sugar and vegetable oil until combined. Add eggs one at a time, mixing well after each.
  4. Stir in buttermilk, white vinegar, vanilla extract, and red food coloring until batter is bright red and smooth.
  5. Slowly fold dry ingredients into wet mixture with a rubber spatula until just combined. Do not overmix.
  6. Divide batter evenly between prepared pans. Tap pans gently to release air bubbles.
  7. Bake for 25-30 minutes or until a toothpick inserted in the center comes out clean.
  8. Cool cakes in pans for 10 minutes, then invert onto cooling racks to cool completely.
  9. Beat cream cheese and butter with an electric mixer until smooth. Gradually add powdered sugar, mixing well after each addition.
  10. Stir in vanilla extract and salt until frosting is spreadable but thick.
  11. Slice each cake horizontally into two layers, creating four layers total.
  12. Arrange three layers side by side on a serving platter to form stripes, leaving space for the star section.
  13. Crumble a small portion of cake or use blueberries for the star area.
  14. Spread frosting between each layer and over the top and sides, smoothing with an offset spatula.
  15. Decorate the blue section with blueberries or white chocolate chips to mimic stars.
  16. Chill the cake in the refrigerator for at least 30 minutes before slicing and serving.

Notes

Use room temperature ingredients for best results. Do not overmix the batter to keep the cake tender. Chill frosting if too soft before spreading. Freeze cake layers before decorating to reduce crumbling. Use a serrated knife to level cake layers and for clean slicing. Keep cake refrigerated until serving to maintain frosting firmness.
