Yes!  Pound cakes freeze wonderfully.  It’s best if you freeze your pound cake before adding the glaze.  Just be sure and wrap the cake well in plastic wrap and then aluminum foil.  If it will fit, place in a freezer bag and store for up to 2 months. Once you are ready to eat, pull from the freezer and store at room temperature, or in the fridge, overnight.  Glaze at least an hour before eating so it has a chance to set.
