Colorful Cupcakes

  • So easy to make, any day can be a celebration! Pick team colors and bake for game day or the holidays.
  • It doesn’t get any easier than a box of cake mix and food coloring! No need to buy the pricey brand, either.
  • Make them as mini cupcakes for halftime, playtime, or game time. So many ways to decorate!
  • A great starter recipe for little bakers and artists.

Ingredients and Variations

CAKE MIX: A vanilla cake mix provides the ideal canvas for rainbow cupcakes, but a yellow cake or a red velvet cake will produce dramatic results, too! And of course, you can always make cake batter from scratch!

FOOD COLORS and MIX-INS: Keep a variety of food colors or gel for swirling. Fun mix-ins are white chocolate chips, mini M&M’s, butterscotch or toffee pieces, toasted coconut, and dried cherries.

TOPPERS: Ice rainbow cupcakes with any color that calls to the artist! Non-pareils, jimmies, chopped peanuts, crushed Oreo cookies, even sugar wafers can be added to the top. Anything goes!

To Frost or Not to Frost?

Rainbow cupcakes can stand on their own. Unfrosted, they can be easily transported in a covered container or a zippered bag for a fun treat to a classroom or the playing field! Or frost with a Vanilla Buttercream Frosting, or Fresh Lemon Buttercream Frosting. Or just use a ready-made cream frosting and mix in a variety of colors.

Tips & Tricks

  • Divide frosting into small bowls and tint with food coloring or gel. Scoop into small sandwich bags and snip off a corner to use for piping frosting on cupcakes. Prepare bags of colored frosting in advance so they’re ready for action!
  • For extra fluffy cupcakes, add an extra egg to the cake mix.
  • To make boxed cake batter taste homemade, follow these tips!

Notes

Nutrition information includes white cake mix only.
If the scoops are too small the colors will become muddled or the colors will mix too much. Adding white batter between the colors will help keep the colors separated, especially if they're colors that won't blend well.
Gel coloring will provide brighter deeper colors.
