Melt one cup of white chocolate chips in a bowl set over a pot of boiling water. Gently stir until the chips have melted. You can also do this in the microwave. Heat the chips in intervals of about 15 seconds, stir and continue to heat as needed. Add orange food coloring, a drop at a time, until you have the color you like.
Add a tablespoon of the melted chocolate into each of the cavities in your chocolate mold. Smooth it up the sides with the back of the spoon, and be careful to get it fully up the sides to the top of the mold.
Refrigerate for a few minutes to set the chocolate.
Add an additional tablespoon of melted chocolate into each of the cavities and repeat the process to ensure that the walls of the chocolate ball will be thick enough. Return to the refrigerator for a few minutes to set.
Gently remove the half balls of the silicone molds. They should come out easily.
Place a plate over the pot of boiling water and let it heat up. Press the rims of half the ball rounds to the plate for a few seconds to even out the edges.
Fill each of those halves with candy such as M&M’s, gummies, mini marshmallows, and candy corn.
Place the rims of the remaining ball halves onto the hot plate to slightly melt the edge. Then press the warm chocolate over the rim of the filled half to seal.
Melt some milk chocolate and use a toothpick to make a jack-o-lantern face on the orange ball.
