How to Make an Easy Rainbow Cupcake Cake


Ingredients

Units Scale
  • 2 (15.25 oz) white cake mixes
  • 6 whole large eggs
  • 2/3 cup oil
  • 1 cup water
  • 16 oz. sour cream
  • 2 (3.4 oz) boxes instant vanilla pudding mix
  • 1 cup flour
  • 3 cups pink frosting
  • 3 cups orange frosting
  • 2.5 cups yellow frosting
  • 2 cups green frosting
  • 2 cups blue frosting
  • 1.5 cups purple frosting
  • 5 cups white frosting

*these are the approximate amounts of frosting I used. This may vary depending on how heavy-handed you are with the frosting, how much you overlap the rosettes, etc.


Instructions

  1. Preheat oven to 325°F.
  2. In a large mixing bowl, add all of the ingredients and mix on medium just until combined.
  3. Using a medium cookie scoop, scoop the batter into a cupcake pan lined with liners.
  4. Bake for 19 minutes.
  5. Allow to completely cool.
  6. On a prepped 20x30 inch board, lay out the cupcakes in a rainbow shape with clouds.
  7. After you're happy with the layout, "glue" them to the board with a dot of frosting on the bottom of each cupcake.
  8. Pipe rosettes on the rainbow, slightly overlaying each color until it's complete.
  9. Pipe white rosettes for the clouds.
  10. Enjoy!
