1Mix cake mix according to the box directions, bake and let cool completely in pan. Use the end of a wooden spoon and poke holes all over the cake.
In a small mixing bowl, stir together the pouch of Jello powder and 1 cup boiling water. Stir until Jello is dissolved. Then add ¾ cup COLD water and mix well. Pour this mixture all over cake with poked holes. Cover cake, then, put in refrigerator and let chill until set. (An hour is plenty of time.)
Pour entire 10 oz. box of thawed strawberries into blender and mix into a liquid. (Do not drain strawberries; use entire box.) Add to the Cool Whip and mix well. Spread over top of chilled cake. Cover cake, and store in refrigerator until ready to serve.
Very Easy. You can use different flavors of Jello liquid to pour over the cake, and then top with plain Cool Whip; or, you can add stuff to the Cool Whip – Example: You could pour orange Jello liquid over the cake, and puree a can of drained mandarin oranges to mix into the Cool Whip topping.
