Melt the dark chocolate on the stove or in the microwave, stirring every minute so the chocolate melts evenly.
Dip the marshmallows into the melted chocolate and place on parchment paper to set. Repeat for all 10 sticks.
Melt the white chocolate and drizzle it over the marshmallow sticks.
Add toppings immediately after drizzling the white chocolate. If the white chocolate sets before you add all of the toppings, dip the toppings in the melted chocolate and place on the marshmallow.
