Ingredients Equipment Method Notes

Ingredients
  

Vanilla cupcakes
  • 1 white or vanilla cake mix Use the box mix plus the ingredients listed on the package (eggs, water, oil, as required).
Buttercream
  • 1 cup unsalted butter Soften before mixing.
  • 4 cup powdered sugar
  • 2 tsp vanilla extract
  • 3 tbsp heavy cream Add 3–4 tbsp as needed for a pipeable texture.
  • 1 red and blue gel food coloring Use gel color for vibrant frosting without thinning.
  • 1 red, white, and blue star sprinkles
  • 1 sparkler picks or flag picks For decoration; insert into the center just before serving.

Equipment

  • 1 sheet pan
  • 1 stand mixer

Method
 

Bake and cool cupcakes
  1. Preheat the oven and bake cupcakes according to package directions in lined muffin tins. Pull them when a toothpick comes out clean, then cool completely on a wire rack for crisp frosting hold.
Make the vanilla buttercream
  1. Beat softened butter until fluffy in a stand mixer. Gradually add powdered sugar while mixing to keep the buttercream smooth.
  2. Add vanilla extract and heavy cream, then beat on high for 3 minutes until very light and fluffy. Stop once the frosting looks pale, airy, and thick enough to pipe.
Color and pipe a tri-color swirl peak
  1. Divide buttercream into three portions, leaving one white and tinting one red and one blue with gel food coloring. Stir each portion until the color is uniform.
  2. Load a piping bag fitted with a large star tip with all three colors side by side for a tri-color swirl. Keep the colors packed together so the swirl forms at the tip.
  3. Pipe a tall swirled peak onto each cooled cupcake. Apply steady pressure to build a dramatic peak that holds its height.
Decorate like fireworks
  1. Shower each cupcake with red, white, and blue star sprinkles over the peak while the frosting is fresh. Aim the sprinkles down the sides so they cascade visually.
  2. Insert a sparkler pick into the center of each cupcake and serve immediately. Place the picks last to keep them looking upright and fireworks-ready.

Notes

Pro tip: If your buttercream feels too thick to pipe, add heavy cream 1 tablespoon at a time; if too loose, add a small spoonful of powdered sugar until it holds a peak. Store unfrosted baked cupcakes tightly covered at room temperature for up to 2 days or in the refrigerator up to 4 days; frosted cupcakes are best within 24 hours for the tallest look. Refrigerate frosted cupcakes up to 2 days, but add sparkler picks right before serving. Freezing is best for the baked cupcakes only (up to 2 months); thaw and frost fresh. For a dairy-light option, use a plant-butter substitute and adjust cream with plant creamer to keep the texture pipeable.
