I was recently baking cupcakes late one evening and realized I had run out of baking cups. With the batter already made and the oven pre-heated, it didn't make sense to run out to the store; so I improvised with what I had, parchment paper. I was pretty happy with the way my home-made wrappers turned out so I figured I'd share for the next time you're in a bind. (Sorry for the horrible iPhone pictures)
I brought these into work the next day, and I think the hand made wrappers made them seem a bit fancier than your typical store bought cupcake baking cups.
