Gather all of your equipment and ingredients. You will need a microwave, microwave-safe bowl, spoon, and silicone chocolate bomb molds for making 12 half spheres.

In a medium microwave-safe bowl, add the chocolate chips. Microwave them on high for just 30 seconds. Stir the chips and return the bowl to the microwave and heat again for 30 seconds. Stir the chocolate to make sure it has all melted.

Working quickly, use the back of a large soup spoon to thinly coat the inside of 12 hot chocolate bomb mold cups.

Place the molds in the freezer for about 7 minutes until the chocolate hardens and sets.

Warm a plate in the microwave for about 45 seconds. Take an empty bomb or sphere and rub the seam side on the warm plate so the edge melts a little. Place the warmed edge over the edge of the filled sphere to close up the bombs and form little balls. Repeat until you have 6 round bombs. You may have to warm the plate again while doing this. You can use any extra melted chocolate to seal gaps in the seams. You want solid balls.

Place the bombs back in the freezer for another 5 minutes until they are set.

Melt the white chocolate chips in a small bowl in the microwave, just as you did for the chocolate chips. Transfer the bombs from the freezer to a plate. Drizzle the white chocolate over the bombs in any pattern you like to decorate them. Place them back in the freezer for a few more minutes until the white chocolate sets.

The bombs can be stored in a container with a lid until ready to use.
