Melt chocolate according to the packages directions
Paint a very thin layer of chocolate in the mold, make sure to bring it all the way up to the edges
Pop the mold into the freezer for 10 minutes
Paint a thin coat of chocolate over the previous layer making sure any thin spots are covered well
Pop the mold into the freezer
If the second layer was thick enough this should be good. Sometimes I have repeated the process with a 3rd layer.
Remove the molds from the freezer and carefully begin removing the chocolate . I found pulling the edges away first and them turning the mold inside out is the easiest method .Just be careful they are very fragile
Heat up a small plate in the microwave
Gently press the open end of the half sphere on the plate and slowly twist to make sure the edges are flat.(only do 2 at a time)
Fill half of the sphere with a few tablespoons of cocoa mix , marshmallows , or whatever you would like
Take the empty sphere and melt and repeat the process on the plate by slightly melting the edges
Gently press the softened edges together
Allow this to cool completely
A little extra melted chocolate can be placed in a piping bag and drizzled over the top and sprinkles on top. This helps hide any imperfections . *SEE NOTES
Serve each hot cocoa bomb in a large mug with about 1 1/2 cups of hot milk
Once the milk is poured over the bomb allow it to sit for 30-45 seconds , then stir until all of the chocolate is melted
