I found this recipe on Pinterest and it's a FAVORITE. Best. Brownies. Ever! Served warm with a scoop of your favorite vanilla ice cream and you've got a nice piece of heaven on earth! Enjoy!! (Thanks Rose...aka The Londoner) The pictures are from The Londoner blog and uses a square baking dish rather than the rectangular dish I use. PLEASE NOTE***The ingredients necessary will vary depending on the cookie dough and brownie mixes you use.
1Preheat oven to 350º. Spray 9x13 baking dish with cooking oil.
2Prepare cookie dough recipe according to the package directions. Add an [extra] teaspoon of vegetable oil and an [extra] teaspoon of water to the mix as it will be in the oven longer than cookie directions. Once dough is ready, press into the bottom of the baking dish taking care to cover the entire bottom of the dish.
3Layer Oreo's on top of the cookie bottom. Only one layer!
4Prepare the brownie mix according to the package directions. Pour the batter over the Oreo's. Bake for 30 minutes to achieve the gooey center depicted in the picture. If you prefer less goo and more chew, bake for approximately 35-40 minutes.
5Let cool a bit before slicing. Serve warm with your favorite vanilla ice cream on top!
