Cookies and Cream Brownies

"I just have no willpower when these brownies are in the house! And whereas I seldom mention a food product by name, there is one and only one Oreo cookie and that's what I call for here. Bake these brownies ahead and freeze them covered in the pan. Or cover and stash them in an out-of-the-way place; if any one finds them they will be eaten." -Anne ByrnFull Story
