Ingredients

Scale
  • 1 1/2 cups (190 g) all-purpose flour
  • 1 cup (200 g) granulated sugar
  • 1 1/2 tsp baking powder
  • 1/4 tsp salt
  • 1/2 cup (115 g) unsalted butter, softened
  • 2 large eggs, at room temperature
  • 2 tsp vanilla extract
  • 1/2 cup (120 ml) whole milk (or buttermilk for extra moistness)
  • For the buttercream: 1/2 cup (115 g) unsalted butter, softened
  • 2 cups (240 g) powdered sugar
  • 1–2 tbsp milk or cream
  • Pinch of salt
  • 1 tsp vanilla extract
  • Red and blue gel food coloring (small amounts)
  • Decorations: fresh strawberries, raspberries, blueberries, or red and blue sprinkles

Instructions

  1. Preheat oven to 350°F (175°C) and line a 12-cup muffin tin with cupcake liners.
  2. Whisk together the all-purpose flour, baking powder, and salt in a bowl.
  3. Beat 1/2 cup softened butter with granulated sugar until light and fluffy, about 2–3 minutes.
  4. Add the eggs one at a time, mixing after each addition, then stir in the vanilla extract.
  5. Add the dry ingredients and the milk alternately to the butter mixture, starting and ending with the dry ingredients; mix just until combined.
  6. Divide the batter evenly among the 12 liners, filling each about two-thirds full.
  7. Bake for 16–20 minutes, or until a toothpick inserted into the center comes out clean.
  8. Let the cupcakes cool in the pan for 5 minutes, then transfer to a wire rack to cool completely.
  9. While the cupcakes cool, beat 1/2 cup butter until smooth, gradually add 2 cups powdered sugar, then add vanilla, a pinch of salt, and 1–2 tablespoons milk to reach a spreadable frosting consistency.
  10. Divide the buttercream evenly into three bowls and tint one pale red and one pale blue with gel food coloring, leaving one bowl white.
  11. Ensure cupcakes are completely cool before frosting.
  12. Pat berries dry before decorating to prevent soggy frosting.
  13. Frost each cupcake with white buttercream first; place blueberries on one corner for the blue field, then arrange sliced strawberries or raspberries in stripes for the red stripes, or pipe colored buttercream stripes or sprinkle red and blue decorations as an alternative.
  14. Chill the frosted cupcakes for 15–30 minutes to set the frosting and, if desired, chill 10–15 minutes then gently press fruit into the frosting to secure the design.
  15. For mini cupcakes, use mini liners and bake 9–12 minutes.
  16. For a chocolate variation, swap 1/4 cup of the flour for cocoa powder.
  17. To make a flag-style sheet dessert, bake the batter in a 9×13 pan, frost with white buttercream, then arrange berries on top to create a flag.
  18. For a no-bake alternative, layer crushed cookies, white pudding or stabilized whipped cream, and berries to make red-white-blue parfaits.
