Step 1

Preheat oven to 350°. In a large bowl, combine dry cake mix, gelatin powder, water and oil. Beat on low speed 1 minute or until moistened; beat on medium 4 minutes.

Step 2

In a small bowl with clean beaters, beat egg whites on high speed until stiff peaks form. Fold egg whites and mashed strawberries into cake batter.

Step 3

Pour into three greased and floured 8-in. round baking pans. Bake 25-30 minutes or until a toothpick comes out clean. Cool 10 minutes before removing from pans to wire racks to cool completely.

Step 4

Spread whipped cream or frosting between layers and over top and sides of cake. If frosted with whipped cream, store in the refrigerator.
