A few years ago, I started making rainbow cupcakes with my children for them to bring to their school’s St. Patrick’s Day celebration. Not only do the kids love eating them, they love making them with me. It is a messy job with a lot of dishes, but it’s well worth the cleanup.
Start by preparing the cake mix according to package directions. I use two boxes because it guarantees that I will have enough to get all six colors into each cupcake. (And I am okay with having some leftover batter in the bowl to lick!) Divide the batter into six bowls.
