Preheat the oven to 325 F. Prepare the brownie mix as directed by combining the mix with the egg, oil and water.
Coarsely crush the Oreos in a large bag with your hands or a rolling pin. I like to leave some pieces pretty big. Pour them into the batter and mix well. Batter will be thick.
Pour batter into a greased square baking pan (mine is about 8×8) and bake for 30-40 minutes. Check doneness by inserting a knife into the brownies; if it comes out mostly clean, you should be good to go. But when in doubt, I’d say underbake!
Notes: I double these ingredients for a 9×13 pan.
