lethal brownies

These are so good, I had to give most of them away that day to avoid the temptation of wanting to eat them all.

1box chocolate cake mix
1stick melted butter
1 egg
Moosh this together with your hands, it's so thick it won't stir.
Line  a 9X13 pan with foil and grease well
Press into pan
Crumble 14-18 Oreos on top
Pour a can of sweetened condensed milk over everything
Top with 11/2C chocolate chips
Bake at 350 20-25 minutes
Next time I think I'll try pecans and heath chips
