Note: Store remaining brownie mix in a heavy-duty, zip-top plastic bag in refrigerator; use mix to make another pie or a small pan of brownies. To make brownies, combine about 2 cups mix, ¼ cup water, and 1 lightly beaten egg white in a bowl. Stir just until combined. Spread in an 8-inch square pan coated with cooking spray. Bake at 350° for 23 to 25 minutes.
