These are a hollow shell of chocolate with marshmallows and flavorings inside. Place them in a coffee mug and pour 8-12 oz of steaming milk over and watch the marshmallows blossom as the chocolate melts. Choose white or dark chocolate, shape and flavors below. If you have special request (such as no marshmallows) type it in the custom text field. We use Ghiradelli melting chocolates.
