Ingredients

Scale
  • 2 ½ cups (315g) all-purpose flour
  • 2 ½ tsp baking powder
  • ½ tsp salt
  • 1 cup (225g) unsalted butter, softened
  • 1 ¾ cups (350g) granulated sugar
  • 4 large eggs, room temperature
  • 1 tbsp pure vanilla extract
  • 1 cup (240ml) whole milk, warmed slightly
  • Red and blue gel food coloring
  • 1 ½ cups (340g) unsalted butter, softened (for frosting)
  • 5 cups (600g) powdered sugar, sifted
  • 2 tsp vanilla extract (for frosting)
  • 34 tbsp heavy cream or milk (for frosting)
  • Red and blue food coloring gels (for frosting)
  • Assorted candy pieces (mini M&Ms, red, white, and blue sprinkles, small gummy stars)
  • Optional: mini marshmallows or edible glitter

Instructions

  1. Preheat your oven to 350°F (175°C). Grease and flour two 8-inch round cake pans, then line the bottom with parchment paper.
  2. In a medium bowl, whisk together flour, baking powder, and salt. Set aside.
  3. In a large bowl, beat softened butter with sugar until light and fluffy, about 4-5 minutes.
  4. Beat in eggs one at a time, mixing well after each, then stir in vanilla extract.
  5. Gradually add the flour mixture in three parts, alternating with warmed milk, starting and ending with flour. Mix just until combined.
  6. Divide the batter: tint one-third red, half of the remaining batter blue, and leave the rest white.
  7. Pour the white batter evenly into the two pans and bake for 25-30 minutes or until a toothpick comes out clean. Cool completely on racks.
  8. Cut a 3-inch diameter circle out of the center of each cake layer using a serrated knife. Save the cutouts for snacking.
  9. Fill the hollow centers with the candy mix, then stack the layers back together.
  10. Prepare the buttercream by beating softened butter until creamy. Gradually add powdered sugar, vanilla, and cream. Adjust consistency as needed.
  11. Tint small portions of frosting red and blue for the flag design.
  12. Apply a thin crumb coat of white frosting over the entire cake and chill for 20 minutes.
  13. Frost the top left corner blue, add white stars with piping or sprinkles, and create red and white stripes on the rest of the cake. Smooth with an offset spatula.
  14. Refrigerate for 30 minutes to firm up the frosting before serving.

Notes

Use parchment paper to ease cake removal. Use gel food coloring for vibrant colors without thinning batter or frosting. Level cake layers for stability. Chill between frosting steps to prevent crumbs. Avoid overfilling candy center to prevent sliding layers. Practice piping on parchment before decorating.
