Instructions

• Grease and flour two 9-inch round pans and preheat the oven to 350°F.
• Combine the white cake mix and strawberry Jell-O, then beat in the egg whites and canola oil until blended.
• Mash the thawed strawberries, reserve 3 tablespoons for the icing, then mix the remaining berries and water into the batter. Pour into the pans.
• Bake at 350°F for 20–25 minutes, until a toothpick comes out clean. Cool 10 minutes in the pans, then cool completely on a wire rack.
• Beat the softened butter and reserved strawberries, gradually adding powdered sugar until light and fluffy.
• Place one cooled cake on a platter, spread with half the icing, add the second cake, and frost the outside.
