Triple Strawberry Cake

1 (18.25 ounce) package strawberry cake mix

1 (3 ounce) package flavored Jell-O®

4 cups water

2 cups frozen whipped topping, thawed

2 cups strawberries, sliced

Prepare cake according to package directions. Bake as directed for a 9x13 inch pan. Allow to cool.

Prepare the strawberry gelatin according to package instructions, using the 4 cups of water. Pour over cooled cake while still in liquid form; the cake will absorb it. Chill in refrigerator for 2 hours, or until gelatin is set.

Spread whipped topping over cake and top with sliced strawberries.
