For the BooHuus Ghost World, decorate the BooHuus cookies with powdered sugar icing, pastry decorations and decorating sugar. Allow icing to set.
Place 1-2 marshmallows on a lollipop stick (paper handle). Spread some chocolate on the marshmallows, place a decorated BooHuus cookie on top and let the chocolate set.
Put the BooHuus Ghost World, for example, in a mug or drinking glass filled with sugar and serve.
