Heat oven to 325°F (350°F for glass pan). Line 9-inch square pan with foil, allowing some to hang over edges of pan. Spray bottom and sides of foil with cooking spray. Make brownie batter as directed on box; spread in pan.

Bake 37 to 42 minutes (34 to 39 minutes for nonstick pan) or until toothpick inserted 2 inches from side of pan comes out almost clean. Cool completely, about 1 hour 30 minutes.
