Hi Linda,

To use canned frosting as a glaze, put some of the frosting in a microwave-safe bowl and heat for a very short time. Check and stir about every 10 seconds (the amount of time you need depends on the power of your microwave). You just want it to get it to the consisitency that you can pour from the spoon. It will continue to melt a little after you stop it so allow for that. If it firms up before you use it you can reheat it again.

I hope that's a help!
