There are many kinds of glazes for bundt cakes that range from chocolate glazes, simple glazes made with confectioners' sugar, and glazes flavored with natural fruits. All of these glazes are thin enough to pour and drizzle over the top of a bundt cake because the traditional method of smoothing icing over a cake would hide the fluted pattern that is made by bundt pans.
Bundt cakes are served either with or without a glaze. Glazing is a thin icing that is drizzled over the bundt cake. A glazing that is too thick to drizzle will need more liquid. Adding a 1/4 teaspoon at a time and mixing until the glaze is thin enough to pour will fix a glaze that is too thick. Before glazing a bundt cake, the cake needs to be cooled on a cake rack. Place the cake rack and bundt cake over a sheet of foil or wax paper so that cleaning up glazing spills is made easy. Use a spoon to drizzle the glaze in a zigzag pattern over the top of the cake. Let the glaze sit undisturbed for 15 minutes before moving the cake to a serving plate.
