Ingredients

Scale
  • 1 ¾ cups all-purpose flour (220g)
  • 1 ½ teaspoons baking powder
  • ¼ teaspoon salt
  • ½ cup unsalted butter (113g), softened
  • 1 cup granulated sugar (200g)
  • 2 large eggs, room temperature
  • 2 teaspoons pure vanilla extract
  • ¾ cup whole milk (180ml), room temperature
  • 1 teaspoon fresh lemon zest
  • Red and blue gel food coloring (optional)
  • 1 cup unsalted butter (227g), softened (for frosting)
  • 3 cups powdered sugar (360g), sifted
  • 1 ½ teaspoons pure vanilla extract (for frosting)
  • 2 to 3 tablespoons heavy cream or whole milk (for frosting)
  • 1 to 2 small packets Pop Rocks candy (classic flavors like raspberry or watermelon)

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 until well combined.
  3. Using a mixer, beat ½ cup softened unsalted butter with 1 cup granulated sugar until pale and fluffy, about 3 to 5 minutes.
  4. Beat in eggs one at a time, mixing well after each, then add 2 teaspoons vanilla extract.
  5. Alternate adding the dry ingredients and ¾ cup whole milk to the batter, starting and ending with the dry ingredients. Mix gently until just combined.
  6. Fold in 1 teaspoon fresh lemon zest gently. If using, divide batter into two bowls and tint one with red gel and the other with blue. Spoon dollops of each color into liners and swirl slightly with a toothpick for a firecracker effect.
  7. Bake for 18-22 minutes or until a toothpick inserted comes out clean. Let cupcakes cool completely on a wire rack.
  8. For the frosting, beat 1 cup softened butter until creamy. Gradually add 3 cups powdered sugar, then add 1 ½ teaspoons vanilla and 2-3 tablespoons heavy cream to reach a fluffy, spreadable consistency.
  9. Pipe or spread frosting generously onto cooled cupcakes.
  10. Just before serving, sprinkle 1 to 2 packets of Pop Rocks on top to keep the fizz alive.

Notes

Use room temperature ingredients for best results. Add Pop Rocks just before serving to keep their fizz. Avoid overmixing batter to prevent tough cupcakes. Cool cupcakes completely before frosting to avoid melting buttercream. For gluten-free, substitute flour with a 1-to-1 gluten-free blend. For dairy-free, use coconut milk and vegan butter alternatives.
