Microwave Canned Frosting in Short Portions for Easy Spreading
The glaze is delicious, but difficult to spread straight from the jar. Just toss it in the microwave in quick batches until it is soft enough to spread.
Toss the icing into a microwave-safe bowl and heat it at 10-second intervals until it is smooth enough to work with, however you plan on using it. Several times you will get the consistency you need to freeze the cake, and a few more times you will make it melted enough to cover the cake pieces by quickly dipping them, or twirl the icing of two colors over a brownie or sheet cake.
