I am doing a cake for a birthday party and it was requested to do a white cake with coolwhip and strawberries/bananas in the center(sort of like a strawberry shortcake). Has anyone ever decorated a cake using cool whip, and, can I decorate the day before and refridgerate or should I do it that morning? Will the borders hold up or fall flat?

if you add some instant pudding to the cool whip you can do shells or borders with it I only tryed it once and did it the day of but everyone loved it i used fresh strawberrys in the middle with a thin layer of buttercream on the top of the bottom layer and under the top layer so the cake didnt get soggie from the strawberrys hope this help.

I have iced a cake with cool whip before, but I haven't tried to really do any decorations with it. Try folding in some strawberry yogurt, it tastes really good!

I use it all the time. I use the reg. size tub of whipped cool whip, I add a few teaspoons of vanilla. I set my mixure on med/high, then add about 5-6 tablespoons of powdered sugar. Mix until it thickens. Once thick stop mixing or it will over mix and become runny. Hope this makes sense. It's one of those things where I can do it, but to explain how to do it.. Well it's tricky. You really have to eye this one. Once thick it decorates very nice. Becareful and be ready to ice the borders fast. It will melt in your hand. Keep in the fridge until ready to use and just fear of it melting. I keep mine in the fridge until ready to cut. good luck!

p.s. if you look at my photos, the chef cake is made with cool whip.
