I've made some sort of peanut butter brownie cupcake with these. All you do it put a little brownie mix in each cupcake holder, then place two Oreos in it (you can also do just one) and put peanut butter either between or ontop of the 1-2 cookie(s). Then just fill the rest of the cupcake holder with the mix, make sure you cover the entire oreo! Then just cook like normal, these have turned out pretty good every time I've baked them. I prefer 1 oreo versus 2, they get kind of heavy.
