Instructions

Make a batch of cake batter using a box cake mix.
We split the cake batter into four equal portions.
Tint the cake batter four different colors - Pink, Yellow, Purple and Blue.
To create the marble effect - use a small spoon to alternate small drops of colored cake batter into the cupcake liner.
Bake the cupcakes as directed on the cake mix box.
Allow the cupcakes to cool.
Make a batch of our Best Buttercream Frosting and color it the same four colors: purple, pink, yellow and blue.
Frost the cupcakes and add sprinkles.
