Separate the cream filling from the Oreo cookies, set aside. In a food processor add the Oreo cookies. Process until crumbs.
Cream together the butter, brown sugar and granulated sugar in a large bowl. Add the vanilla and eggs, mixing well. Combine the flour, baking soda and salt in a separate bowl. Add the dry ingredients and Oreo crumbs to the wet ingredients.
Add half the dough to a 10-12 inch skillet. Top with Hershey’s bars and the filling of the Oreos. Add other half of the dough. Sprinkle the semi-sweet chocolate chips.
Bake for 30 minutes. Top with white chocolate chips. Let sit for 10-15 minutes before digging in!
