Does Dream Whip icing need to be refrigerated? I made a batch to use on a cake that I will be decorating tomorrow and am wondering if I can leave the icing out until then, or if I need to stick it in the fridge.
You will be fine with it over night on the counter.
I made a batch about a week ago and kept some from it to find out how long it would last. Been a little over a week and it's still looking good. There isn't anything in the recipe that would spoil that fast though. I used a recipe with the same ingredients you have listed.
