Ok, so I saw this concept on Pinterest but decided to make them in a muffin tin (the recipe was baked in a 9x13 pan). Reason being: I wanted to take something to my neighbor's Superbowl Party but didn't want to deal with bringing my pan, cutting it, etc. This way the guests can grab one and go watch the game.
This actually didn't take long to prepare.
Both adults and teeny-bops were excited to try these - which I was surpised about. Guess this combo brings out the kid in everyone.
You can use any cookie recipe you want. I didn't have any pre-made dough on hand so I just made a chocolate chip cookie dough recipe without the chocolate chips (I did make choc. chip cookies from the leftover dough). I sprayed the muffin tin with Pam and then put a layer of cookie dough in each section. I topped it with an oreo cookie.
I scooped my brownie batter and poured it over the cookie/oreo combo.
I baked it at 350 for about 20-25 min. Not long. My oven runs hot so I would adjust the baking time to your oven.
