Why does the surface of a cake frosted with Rich & Creamy or Whipped frosting look wet and/or lighter in color?
A. Two things can cause this to happen. First, the cake was covered too tightly, so moisture from it condensed on the frosting. To let the cake “breathe,” try either placing the blade of a knife under the cake cover, folding back a corner of the aluminum foil or plastic wrap or opening the lid of the pan a bit. The second thing is the foil or plastic wrap may have touched the frosting for too long. That’s the spot where the frosting will get lighter in color and begin to “weep.” To keep the wrap or foil from touching the frosting, make a “tent” by sticking a few toothpicks into the top of the cake.
