This is the moistest cake you will ever eat. I love it with strawberry jello and garnished with fresh strawberries. The Cool Whip makes such a pretty pure white and creamy frosting. It was my mom's favorite birthday cake. Prep time is also chill time

I made this as a birthday cake for my husband. Used a Betty Crocker French Vanilla cake, and strawberry jelly, with fresh strawberries. I used whipped cream in place of cool whip. Lots of 'mmm mmmm's' to be heard, thanks Karen!

I made this cake for my niece's birthday. Very beautiful and colorful. I was impressed with how moist the cake was. I used strawberry jello. The Cool Whip frosting was light and not so sickeningly sweet like those buttercream frostings. Thanks for sharing this recipe. A hit with both kids and adults.
