Cookies and Creme Brownies

As I've said before I have 5 children and so I am always looking for fun and easy recipe.  Unfortunately I can't take credit for this recipe, I actually saw it on the back of the box. With a name like Cookies and Creme Brownies, how could I resist giving them a try?  They were very simple to make, and my children really liked them.  The brownies looked yummy.  I thought they were a little too sweet, but still think they would make a great dessert to take for a covered dish.

1 box fudge brownie mix (9x13 size)
1 3/4 cup Oreo cookie crumbs
1 container vanilla frosting.

Preheat oven to temperature listed on the box. Mix up the brownie mix as directed on the package. Then add 1 cup of cookie crumbs to the batter.  Pour into a greased 13x9 pan and bake for the time stated on the box.*  Allow the brownies to cool completely.  Spread the vanilla frosting on top of the brownies and then sprinkle the remaining cookie crumbs on top.

*I'm not crazy about gooey brownies so I might increase the cooking time by a few minutes the next time I make them.
