In a large bowl combine the sugar, unsweetened cocoa powder, and semi-sweet chocolate. Mix well and set aside.
Using a funnel, pour 1/2 cup of the cocoa mix into each ornament.
For the peppermint hot cocoa, place about 3-4 tablespoons of peppermint marshmallows on top of the hot cocoa mix. Sprinkle with 1-2 tablespoons of crushed peppermints. Put the lid on the ornaments.
For the triple chocolate hot cocoa, place 1-2 tablespoons of semi-sweet chocolate chips on top of the hot cocoa mix. Then place 3-4 tablespoons of mini marshmallows on top of the chocolate chips. Finally, sprinkle 1-2 tablespoons of mini chocolate chips on top of the marshmallows. Put the lid on the ornaments.
To finish the ornaments type up a slip of paper saying, "To make the hot cocoa, shake the ornament to combine the ingredients. Pour 3-4 tablespoons of mix and marshmallows into 1 1/2 cups of steamed milk. Stir well and enjoy."
Tie the paper onto the ornament with pretty ribbon and give as gifts!
