Prepare snowflake shells: In a medium bowl, melt White Candy Melts Candy according to package directions.
Using a decorating brush and the melted Candy Melts Candy, paint the inside of the snowflake mold cavities. Place molds in the refrigerator to set, about 5-10 minutes.
Remove mold from the refrigerator and paint a second layer of White Candy Melts Candy over the first set layer. Allow the second layer to set.
Continue the painting and setting layers until candy is about 3/16 inch thick to create a shell.
Once the shell is created, take a knife and level the top of the shell.
Make the ganache: Finely chop Light Cocoa Candy Melts Candy into pieces. Add whipping cream to a medium saucepan and bring to a simmer. Cream will start to steam, and the edges will start to bubble.
Remove from heat and add in the chopped Candy Melts Candy. Stir until smooth and glossy. The mixture may appear lumpy or broken while stirring, continue stirring and it will come together.
Remove saucepan from heat and allow mixture to chill until cool, not firm, about 10 minutes.
Fill snowflake shells with ganache. Prepare a decorating bag with chocolate ganache. Cut a small hole in the tip of the bag and squeeze ganache filling into shells leaving a 3/16 inch space at the top.
Allow ganache filling to set. Next, use a decorating brush to paint a top layer of white Candy Melts Candy onto the top of the ganache to complete the snowflake shell.
Chill to set, about 5-10 minutes. Once firm, gently press the bottom of cavities to release.
