Pre heat oven to 325, prepare muffin tin with cups.

Make both cookie/brownie mix how instructed in seperate bowls.

Spoon out cookie dough into cups, press dough to bottom and form a flat layer, approx 1/2 inch from bottom of cup. You can eyeball amount, like a normal sheet cookie just pressed flat in cup.

Spoon a heaping tablespoon of brownie mix over the top of cookie dough.Only fill cups 1/4-1/2 in from the top, they'll rise.

Bake at 325 for approximately 20 min, depending on size cook time could vary. Check often with a toothpick if dough from cookie or brownie is on toothpick cook longer

Let cool. Cookies are very rich, I cut into manageable pieces. You can freeze these.
