Take your two cups of strawberries and crush them with a fork. Pour into a greased 9×13 in cake pan. Sprinkle strawberry Jell-O over the top of the strawberries. Then sprinkle the marshmallows over the Jell-O.

Prepare cake mix according to package directions. Pour over the marshmallows.

Bake at 350 degrees for 40-50 minutes or until cake tests done. Let sit for about 15 minutes and then run a knife around the outside of the cake. Flip onto a serving tray. Refrigerate.

Serve with Cool Whip
