  • Eggs: 3 large
  • Butter: ⅓ cup, melted and unsalted
  • Milk: ½ cup (whole or 2%)
  • Water: ½ cup
  • White or Yellow Cake Mix: 1 box
  • Rainbow Food Coloring: Red, orange, yellow, green, blue, purple
  • Homemade Whipped Cream: 6 cups
  • Rainbow Sprinkles: ¼ cup


  1. Prepare the Batter: In a large mixing bowl, whisk together eggs, melted butter, milk, and water until smooth. Stir in the cake mix until just combined, taking care not to overmix to keep the cupcakes light and fluffy.
  2. Color the Batter: Evenly divide the batter into six separate bowls. Add a different color of food coloring to each bowl, mixing well until the colors are vibrant and uniform.
  3. Bake the Cupcakes: Line a cupcake tray with liners and fill each halfway with the multicolored batter to ensure even cooking and consistent size. Bake in a preheated oven at 350°F for 16-20 minutes or until a toothpick inserted into the center of a cupcake comes out clean.
  4. Cool and Frost: Allow the cupcakes to cool completely on a wire rack. Meanwhile, prepare the whipped cream. Using a piping bag fitted with a large round tip, generously frost each cupcake.
  5. Decorate: Add a playful touch by sprinkling each cupcake with rainbow sprinkles, enhancing their festive look.

Baking Tips:

  • Color Vibrancy: For more intense and vibrant colors, opt for gel food coloring, which provides saturation without thinning the batter.
  • Frosting: Ensure the cupcakes are completely cool before applying whipped cream to prevent it from melting.
  • Creative Variations: Consider adding a surprise inside by filling the cupcakes with sprinkles, small candies, or a dollop of your favorite jam.
