Housewarming gift... Are your friends registered? Check that first. Go to Crate and Barrel or Bed Bath and Beyond or wherever they are registered. Look on the registry and see if they are registered for cupcake pans, cake carrier, pie dish, sheet pan or a cake plate. Make cookies, pie, cake or cupcakes and deliver them in the dish. Put a bow on the top and you are all set.
If they aren't registered pick up a serving piece and do the same thing. You can never have too many serving pieces.
Always nice to have something sweet in the house!
