Ingredients

Scale
  • 1 ¾ cups (220 g) all-purpose flour
  • 1 ½ teaspoons baking powder
  • ¼ teaspoon salt
  • ½ cup (115 g) unsalted butter, softened
  • 1 cup (200 g) granulated sugar
  • 2 large eggs, room temperature
  • 2 teaspoons pure vanilla extract
  • ¾ cup (180 ml) whole milk, room temperature
  • 1 cup (230 g) unsalted butter, softened (for frosting)
  • 3 ½ cups (440 g) powdered sugar, sifted
  • 1 ½ teaspoons pure vanilla extract (for frosting)
  • 23 tablespoons whole milk or heavy cream (for frosting)
  • Red, white, and blue gel food coloring (optional)
  • Pop Rocks candy, assorted flavors (about ½ teaspoon per cupcake)

Instructions

  1. Preheat oven to 350°F (175°C) and line a 12-cup muffin tin with cupcake liners.
  2. In a medium bowl, whisk together flour, baking powder, and salt.
  3. In a large bowl, beat ½ cup softened unsalted butter and granulated sugar on medium speed until light and fluffy, about 3-4 minutes.
  4. Beat in eggs one at a time, mixing well after each addition, then stir in vanilla extract.
  5. With mixer on low, alternate adding the dry flour mixture in three parts with ¾ cup whole milk, beginning and ending with dry ingredients. Mix just until combined.
  6. Spoon or scoop batter into liners, filling about ⅔ full.
  7. Bake for 18-22 minutes or until a toothpick inserted in the center comes out clean or with a few moist crumbs. Cupcakes should spring back lightly when touched.
  8. Remove cupcakes from tin after 5 minutes and transfer to a wire rack to cool completely.
  9. Prepare buttercream frosting by beating 1 cup softened butter until creamy, gradually adding powdered sugar. Add vanilla and 2-3 tablespoons milk or cream to reach desired consistency. Divide frosting into three bowls and tint with red, white (plain), and blue gel food coloring if desired.
  10. Right before serving, create a small hole in the center of each cupcake and fill with about ½ teaspoon Pop Rocks. Cover lightly with a bit of frosting to seal.
  11. Pipe or spread the tri-colored frosting on top, swirling gently to mimic fireworks. Sprinkle extra Pop Rocks on top for sparkle.

Notes

Add Pop Rocks right before serving to keep the popping effect fresh. Avoid overmixing the batter to keep cupcakes light and tender. Use unsalted butter to control salt level. For gluten-free, substitute all-purpose flour with a 1:1 gluten-free baking flour blend. Refrigeration dulls Pop Rocks fizz; store cupcakes at room temperature and frost just before serving.
