If you'd like to make your own, might we recommend this recipe for the oatmeal cookie crust and then just double this recipe for the brownie. You're going to bake both in a 9x13 pan - the crust first, as the recipe suggests, and then the doubled brownie recipe on top. As far as brownies go, the recipe really can't be beat. Yes, you really do have to stir them for one full minute, but multi-tasking gals like ourselves appreciate the arm workout. Any questions? Let us know in the comments section below.
