Some cakes and other desserts wouldn't be the same without frosting or glaze. Sweets such as glazed donuts, marzipan and rum cake would fall flat without glaze drizzled on top. Glaze needs to be thin enough for cooks to pour on top of desserts without having to use a spatula to spread it. You can make a glaze from scratch, but if you are in a hurry, it's easy to use canned or premade frosting to make a quick glaze.
Pour canned or premade frosting into a small microwave-safe bowl.
Microwave the frosting on high for about 30 to 45 seconds. Open the microwave and stir the frosting every 10 seconds or so to check the consistency. The glaze is ready when it is slightly translucent and loose enough to pour.
Remove from the microwave and pour onto your prepared dessert as you normally would.
