Hot chocolate bombs are exploding on Internet, so we thought we'd give it a whirl too. Perfect for the holidays, these hollow chocolate balls are filled with cocoa powder and marshmallows, so that when hot milk is poured over the top, the chocolate bursts open, turning the mug of milk into a delicious hot chocolate. Although you could make this with any old chocolate bar, Spicy Hot Cocoa Bombs Ideas here, which is made specifically for melting. It also stuck to the classic get-up for hot chocolate, but feel free to fill your bombs with coconut flakes, sprinkles, crushed peppermint, or spices like cinnamon or cayenne powder. To store, keep these in an airtight container in a cool spot in your kitchen or the refrigerator.
