Like everyone else who's seen this Rainbow Cake, I've wanted to try to make one. Christopher's Birthday cupcakes seemed like the perfect opportunity so I did all of the Sesame Street cupcakes rainbow on the inside. I didn't want them to be a perfect upside-down rainbow inside, so I tried to spread around the blogs of color in each cupcake. I thought it'd be a nice little surprise for the kids when they ate them but they didn't seem to think it was as cool as the adults did. I thought they looked neat and the inside of the cupcake wrappers looked pretty too!
