I have seen full Cakes from hackgadgets website made this way before and had some trouble deciding on the flavor of the cake. My sister is fond of chocolate icing which would look gross on such a pretty cake. She suggested that cupcakes were the way to go to allow more range of choices.
You will need everything you need for a normal white cupcakes with fluffy icing and some misc items.
-Cake Mix and Icing Mix
-White cup cake holders
-Some measuring cups
-Rainbow sugar sprinklers
-(optional) A small cookie scoop
Step 1: Dividing the Mix
I divided the mix into six bowls using decreasinly small measuring cups.
Based on the number of drops needed to color a full cake you will need to divide the drops by six for each bowl.
Cheaper white cupcake holders were chosen to allow the color to be easily seen through the paper.
