Cupcake mild fever

I must admit, I got hit by the cupcake fever a bit late. It suddenly came about a month ago, and 48 cupcakes later, I've recovered. All the frosting and decorating and witnessing the oohs and aahs emitted from guests were quite fun though, while it lasted.

Now that the mild fever has gone... what am I to do with the 2 boxes of muffin ready-mix I didn't really get to use?
