To assemble your house, take a plastic bag or a piping bag and fill it with your prepared I’ve seen. If you have a frosting tip, we do recommend using it.
When your bag is filled with frosting, take the cut vertical piece, and face the frost inside of a popped tart out. Next, take a horizontal pop tart with frost inside facing out. Frost one side of your corner with icing, then stick them together. Hold them together until the icing is set.
When the icing is set repeat this process with the adjacent side, and back of your pop tart gingerbread house. When the walls of the house have set, attach the roof. Allow the house to completely dry and set before decorating.
