Begin by layering a greased 9 x 13 baking dish with chocolate chip cookie dough. If you want to make your cookie dough from scratch, go for it, but I usually use pre-made dough - Yes, those break and bake packages of cookie dough work perfectly! Just press it all together making a nice even layer across the bottom of your pan.

Layer Oreo cookies on top of the cookie dough - This is the easiest step of all!

Prepare your favorite brownie mix (We love the Ghiradelli Brownie Mix OR the Hershey's Brownie Mix from Sam's Club!), and then pour it over the Oreos!

Bake on 350 degrees for approximately 30 minutes, and bam!
