Ooey Gooey Brownies

I package of brownie mixed prepared as per box. In a 9"X9' pan place foil so there is an overhang for easy liftout. Spray foil with cooking spray. Spread half of brownie batter in pan. Place 16 peanutbutter cups in rowns on the batter. Now spread remaining batter over the cups and bake as per box for 9"x9" pan.
