Ingredients

• Cooking spray

Preparation

1. Preheat oven to 350°.
2. Coat a 9-inch square baking pan with cooking spray; dust with 1 tablespoon flour. Set aside.
3. Cream margarine. Gradually add sugar; beat at medium speed of a mixer until well-blended. Add vanilla, egg whites, and egg; mix until blended. Combine 1 1/2 cups flour and baking powder; with mixer at low speed, add dry ingredients to creamed mixture. Reserve 1 1/2 cups of batter; pour remaining batter into a bowl.
