Cake in a cup

This is like cake magic.  Did you know such a thing was possible?  That's funfetti cake in a Harley Davidson mug.  Cooked in the microwave!  I don't even have to use such a large mug for my next batch.  I could probably use a little Crate and Barrel prep cup.  Totally going to make these at school with the children.  They will think it's magic for sure!

ETA:  How cute is this?!

I should also add:  how yummy is this? 

Super yummy!
