1 cup of cake batter and Oreo ice cream (OR 2 scoops cake batter, 1 scoop Oreo) 1/2 cup milk (I use whole skim but any type works) 1/8 cup chocolate sauce ice (optional - I've never tried it, but I hear it works)
Mix all ingredients into blender. I like mine thick, but you can do it however you like it.
