Melt your chocolate using a double boiler or by microwaving in 30 second increments stirring in between.
Spread the melted chocolate in your molds in an even layer using a spoon or silicone brush.
Put your mold in the fridge for about 30 minutes or until hardened.
Remove from the molds, and fill 3 halves with 1 Tbsp of hot chocolate mix each and several marshmallows.
Warm a plate in the microwave and then press the edge of the empty halves against it and then press them onto the filled halves.
Melt the pink and white candy melts and drizzle across and then sprinkle with sprinkles, allow to harden.
To use- place in a mug and pour over 8-10 ounces of hot milk, and stir.
