What is a hot chocolate bomb? Individual chocolate spheres are filled with cocoa mix and marshmallows. You place the “bomb” in a mug, pour 10-12 ounces of hot milk, water or coffee over it to dissolve the chocolate and – like magic – watch the marshmallows float to the top. A quick stir mixes everything together.Min. order of 4GREAT STOCKING STUFFER!**Due to the popularity of this product, please allow extra processing/production time.
