Ingredients

•     1 package white cake mix (regular size)
•     1 package (3 ounces) strawberry gelatin
•     1 cup water
•     1/2 cup canola oil
•     4 egg whites
•     1/2 cup mashed unsweetened strawberries
•     Whipped cream or frosting for your choice

Directions

    In a large bowl, combine the dry cake mix, gelatin powder, water and oil. Beat on low speed for 1 minute or until moistened; beat on medium for 4 minutes.
    In a small bowl with clean beaters, beat egg whites on high speed until stiff peaks form. Fold egg whites and mash strawberries into cake batter.
    Pour into three greased and floured 8-in. round baking pans. Bake at 350° for 25-30 minutes or until a toothpick comes out clean. Cool for 10 minutes before removing from pans to wire racks to cool completely.
    Frost with whipped cream or frosting. If frosted with whipped cream, store in the refrigerator. Yield: 12-16 servings.
