Yesterday was my son's 3rd birthday (I can't believe how fast he is growing!) and we made rainbow cupcakes to celebrate it (just us at home, the party is this weekend) as well as to bring to preschool to share with his friends.
I used this recipe, in case you are interested. It has the amount of drops you should use to make the colors nice and vibrant.
After they cooled down, I put some whipped cream on top, lit 3 candles and sang happy birthday.This is what the cupcakes look in the inside. Fun, isn't it?
