Melt chocolates according to the directions on the bag.
Use a spoon to coat each mold and chill 10 minutes.
Spoon on another thin layer and chill.
Remove each from the mold.
In half, place your cocoa mix (fill halfway) and load on some mini marshmallows.
Line the edge with melted chocolate and top with the other half to seal together.
Place the extra chocolates in piping bags and drizzle on top.
Decorate with crushed oreos or sprinkles/candies.
To serve, place a bomb in a jumbo mug.
Heat your milk until hot and pour over the bomb.
Watch the magic happen.
Drizzle caramel sauce on top, if desired and whipped cream!
