In a food processor, blend 1 and 1/2 rows of Oreo cookies.

Then add 3 Tablespoons of melted butter. Blend again.

The cookie crumble should hold together when you pick it up and squish it in your hand.

Spread and press the oreo mixture to the bottom of a sprayed crockpot. 

Place pieces of the cookie dough over the oreo mixture to cover it.

Cook on low for 2.5 hours and let it sit a little bit. It'll look gooey in the middle, but as it rests, it will harden slightly.

Serve with ice cream and chocolate fudge.
