Preheat the oven to 375 degrees, and line a square 8x8 baking dish with parchment paper
Pour the brownie mix onto the bottom layer and spread out evenly
Drizzle the nut butter throughout the pan evenly
Drop generous spoonfuls of the cookie dough on top, and scatter evenly throughout the pan
Bake for 25-30 minutes. I like mine soft baked, so I stay on the 25 minute side of things.
Cool completely before slicing and serving.
