Begin with melting white chocolate in a bowl in the microwave for 2 minutes.
Next, dip the tops of the mini ice cream cones in the white chocolate and set them aside to set.
Then, fill round molds with white chocolate and let them sit for 10 minutes in the freezer, remove chocolate from molds and gather hot chocolate and mini marshmallows.
Heat a small skillet and remove from heat, place one side of the chocolate mold down and melt the edges until they are smooth.
Next, fill with hot chocolate and mini marshmallows, melt the top of the second piece of chocolate from the mold, and place on top of the other half filled with hot chocolate.
Repeat. Then dip the bottom of one hot chocolate bomb in the leftover white chocolate and dip the end of the mini cone in white chocolate again and place the cocoa bomb on top of the cone.
Drizzle the top of the cocoa bomb with white chocolate and add sprinkles.
Place in a mug filled with hot milk and let the chocolate bomb melt and mix with hot milk.
Stir and enjoy hot chocolate!
