Yummy "Layers of Crap"

Made this yesterday for a little Pinterest Party at my house with fellow MOPS (moms of preschoolers). I found it on Pinterest but didn't see a name for it so I'm dubbing it "layers of crap". And by crap, I mean seriously yum but not-so-good-for-you.

Grease muffin tin
Layer chocolate chip cookie dough, Reece's peanut butter cup, and top with brownie batter. About 3/4 full. Cook at 350 for 18-20 minutes. Holy calories. Enjoy!
