Yes, you read that correctly. I have only one word – OMG (ok, that might be three words, but whatever). I saw these on pinterest, linked back from a blog, but it’s not even really a recipe so I think I can just instruct you here.
Get a pack of Oreos.
Spread about a TBSP of peanut butter atop two Oreos and stack them inside a cupcake liner in a muffin pan.
Prepare boxed brownie batter. Pour 2 TBSP of prepared brownie batter over each Oreo stack. Bake for about 20 minutes (probably about time on package).
