Ingredients

Scale

Cupcake Batter

  • 1 cup butter, softened
  • 2 1/3 cups sugar
  • 5 egg whites
  • 1 tablespoon vanilla extract
  • 3 cups all-purpose flour
  • 4 teaspoons baking powder
  • 1/2 teaspoon salt
  • 1 1/2 cups milk, warmed to room temperature
  • Gel food coloring in red, orange, yellow, green, blue, and purple

Vanilla Cloud Frosting

  • 1 cup butter (2 sticks), softened
  • 4 cups powdered sugar, sifted
  • 1 tablespoon clear vanilla extract
  • Tiny pinch of salt
  • 3 tablespoons milk

Instructions

  1. Preheat Oven: Preheat your oven to 350 degrees Fahrenheit to ensure it’s at the right temperature once your batter is ready.
  2. Cream Butter and Sugar: In a stand mixer, cream the softened butter and sugar together for 2-3 minutes until the mixture is much lighter in color, resembling a soft spring yellow. This creates a light and fluffy base for your cupcakes.
  3. Add Egg Whites and Vanilla: Beat in the egg whites and vanilla extract until fully incorporated, giving the batter structure and flavor.
  4. Prepare Dry Ingredients: In a separate bowl, mix the flour together with the baking powder and salt to ensure even distribution.
  5. Combine Wet and Dry Ingredients: Alternately add the dry ingredients and the warmed milk to the batter, starting and ending with the flour mixture. Add about 1 cup of flour, then ½ cup milk, repeating until fully combined. This step ensures the batter is smooth without overmixing.
  6. Divide and Color Batter: Divide the remaining batter evenly into 6 separate bowls. Add gel food coloring to each bowl to create red, orange, yellow, green, blue, and purple batters. Stir each color well to achieve vibrant and even colors.
  7. Layer Batter in Cupcake Pan: Use either a small spoon or piping bags to layer the colored batters into cupcake liners. Start with purple at the bottom, then blue, green, yellow, orange, and finally red on top. Each layer should be thin, about a ¼ inch thick, to create distinct rainbow stripes inside each cupcake.
  8. Bake: Place the cupcake pan in the preheated oven and bake for 18-20 minutes, or until a toothpick inserted into the center comes out clean. Remove from the oven and allow cupcakes to cool completely before frosting.
  9. Make Frosting: In a stand mixer fitted with a paddle attachment, whip the softened butter until lighter in color and fluffy, about 1 minute. Add in the clear vanilla extract and mix briefly.
  10. Add Powdered Sugar and Milk: Gradually add powdered sugar 1 cup at a time, alternating with 1 tablespoon of milk as you go. After each addition, beat on high speed for 1 minute until the frosting is super light, fluffy, and a creamy vanilla cloud texture. Finish with the last cup of powdered sugar.
  11. Frost Cupcakes: Using a piping bag fitted with a closed star tip, pipe the frosting onto the cooled cupcakes in decorative swirls or peaks for a beautiful finishing touch.

Notes

  • Use clear vanilla extract in the frosting for a whiter appearance; regular vanilla will give a creamy tint.
  • Warming the milk to room temperature prevents it from cooling the batter and helps maintain the proper consistency.
  • Gel food coloring is recommended for vibrant colors without thinning the batter.
  • Ensure cupcakes are completely cool before frosting to prevent the buttercream from melting.
  • For layered batter, piping bags allow for more precise and neat layers than spooning.
