Easy Rainbow Muffin

A Rainbow Cake that is very easy! I am using a french vanilla box cake mix since I have one that I bought long time ago (it is too cheap to not buy >.<). How to make it more appetizing and lovely? Add in Colors! I have never attempted any rainbow cake before, so I am thinking of giving it a try.

Ingredients & Steps:
1 vanilla cake mix (you can use any cake recipe you like, preferable white cake or yellow cake, not chocolate cake; follow the instructions on the box cake mix)
Prepare 4 colors (I only have 4 colors, I guess I cannot call it a rainbow cake then)
Divide the cake mixture into 4 bowls evenly, mix in the colors. Alternately put different colors of batter into a cupcake or muffin tins. Mine came out more like muffins. I bake it at 350 F for 20-25 minutes. Cool completely. It came out very moist and fluffy.

Look at the lovely vibrant colors! =D

Happy baking =)
