St. Patrick’s Day is almost here and it’s the perfect to time to make some rainbow treats!  These cupcakes are easy to make and a big hit with the kids.  I love how bright and festive they are!  (However, be warned that if you use food color drops instead of the concentrated gels, the colors won’t be nearly as bright – they will turn out more pastel.)  Hope you all have a great holiday and keep those pesky little leprechauns from making too much mischief at your house. ;)

Rainbow Cupcakes
Serves: 24
  • 1 white cake mix (prepared as directed on box)
  • Wilton concentrated gel icing colors
  • Buttercream Icing
  • ½ cup butter, softened
  • 4 cups powdered sugar
  • 1 tsp vanilla extract (I left this out because I wanted the frosting to be very white)
  • 3-4 Tb milk
  1. Divide prepared cake mix equally into 5 bowls.
  2. Place a small amount of food coloring gel in each bowl and mix to combine - I used red, yellow, green, blue and purple.
  3. Line muffin tin with cupcake liners.
  4. Drop a spoonful of each colored cake mix into each cupcake liner until all the cake mix is used up. Bake at 350 for 15-18 minutes.
  5. Allow to cool completely then frost with buttercream icing and rainbow sprinkles.
  6. Store in refrigerator to maintain frosting texture.
  7. In a mixing bowl, cream butter.
  8. Beat in sugar and vanilla.
  9. Add milk until frosting reaches desired consistency.
  10. Makes 24 cupcakes
