Amy, I do it all the time...only it is for me not him! I generally buy a 6 inch cake, have one piece & wrap individual pieces in foil & freeze...same way with a pie, cut the wedges & freeze...sweet rolls, donuts, the list is endless....brownies now come in one size portions, just microwave for a bit & they're done...not need to freeze them, or make a batch & freeze in portions...
