This easy Rainbow Cupcakes recipe is made with a simple white cake mix and food coloring in a rainbow of colors.


  • 1 box white cake mix
  • food coloring


  • Preheat oven to 350˚F. Line muffin tin with parchment liners.
  • Prepare cake mix according to directions on the box.
  • Separate cake batter into individual bowls, one for each color you want. Add food coloring to each bowl until desired colors are achieved, blending well.
  • Place ½ teaspoon of white batter in the middle of each muffin cup. Add ½ teaspoon of colored batter onto the center of the white batter.
  • Repeat with each color, dropping it carefully into the middle of each previous puddle of batter. Continue until muffin wrappers are ½ full.
  • Bake for 12 minutes, or until a toothpick inserted into the middle of a cupcake comes out dry.


Recipe note: add food coloring a drop at a time until desired brightness is achieved.
Cupcakes can be frosted and decorated as desired. Try rainbow sprinkles on top!
