I like to glaze my pound cakes while they are still hot and in the baking pan. I prepare a light syrup with whatever flavor and poke holes in the hot cake using a poultry skewer. then I pour the syrup over the cake. Let the cake rest in the pan until it is completely cool. Then take it out of the pan. the glaze will have gone through the cake and be on the outside! I almost always freeze at least part of every cake, and the glaze stays put just fine that way. Give it a try!

I like ChefJune's method because it makes for a super moist and juicy cake but if you want an alternative, you could freeze the cake unglazed and then glaze it after you defrost it when you're ready to eat it.
