Preheat oven to 350°.
Step 2 Beat sugars and butter at medium speed of a mixer until well-blended (about 4 minutes). Add egg whites and vanilla; beat well. Lightly spoon the flour into dry measuring cups, and level with a knife. Combine flour, baking powder, and salt; stir well with a whisk. Add flour mixture to sugar mixture; beat at low speed just until blended. Spread batter evenly into an 8-inch square baking pan coated with cooking spray; sprinkle evenly with topping option.
