Glaze adds a shimmery look and extra sweetness to baked goods like Bundt cakes and brownies. You can make a glaze by heating water, confectioner's sugar and a little flavoring, but a homemade glaze requires some know-how to get it just right. To save time, buy a can of store-bought frosting and heat it up to make a delectably creamy, pourable glaze. Heating up frosting is also an effective way to use leftovers from other baked goods.
Spoon as much frosting as you need into a microwave-safe bowl. Heat it on high for about five to 10 seconds. Take the frosting out of the microwave and stir it with a spatula, so that any remaining lumps melt. When you scoop up some frosting, it should run off the spatula like a thick sauce -- similar to ganache. You may need to heat it for a few more seconds, depending how much you have in the bowl, but it should take no more than 45 seconds.
If you don't have a microwave, place a saucepan on the stove over low heat. Spoon the frosting into the pan.
Stir the frosting continuously as it warms up, which may only take a few minutes depending on your heat source and the type of saucepan you use. Remove it from the heat when it has the consistency of a thick sauce and pour it over your baked goods.
