• 1/3 cup unsweetened cocoa powder
• 2 tablespoons cornstarch
• 1/2 teaspoon baking soda
• 1/2 teaspoon baking powder
• 1/3 teaspoon salt
• 4 large eggs, separated

• 1 (8 ounce) container whipped topping, thawed

1. Preheat oven to 350u0b0F.
2. Line a 15x10-inch jelly roll pan with waxed paper. Grease and flour lined pan; tap out excess.
3. In a medium bowl, combine flour, cocoa powder, cornstarch, baking soda, baking powder, and salt. Mix well.
4. In a separate bowl, using an electric mixer, beat egg yolks and 1/4 cup sugar until fluffy. In a small bowl, using CLEAN beaters, beat egg whites on high until foamy. Gradually add 1/2 cup sugar, beating until stiff, but not dry, peaks form.
