Melt white almond bark according to package directions. I melt it in a microwave-safe bowl in 30 second intervals until melted.
Once melted, stir in a few drops of green OIL BASED food coloring until desired color is achieved.
Using a spoon, fill each cavity of the tree mold with some of the melted green chocolate.
Use the back of the spoon and spread the chocolate around the center, sides and bottom of the mold. We're just creating a shell here so the center does not need to be filled.
Make sure that the sides and bottom are coasted well.
Let the chocolate sit for about 15 minutes for it to harden.
Save extra chocolate to glue half circles together later. You may need to carefully reheat this when it's time to use it.
Carefully turn silicone mold over onto a flat surface and pop trees out of mold.
Each hot chocolate bomb will need two trees.
If you want the front of the tree to shimmer, carefully brush green luster dust over 3 of the trees.
Fill 3 trees with 1 tablespoon of hot chocolate mix and 1 tablespoon of marshmallows each.
Top with a hollow trees and use the extra melted left over chocolate and a butter knife to ""glue" the two pieces together. OR you can heat a plate with hot water, wipe it clean and then use it to melt the top seam edge and stick it to the bottom tree. If you do this, you may need some extra melted green almond bark to make sure there are no gaps.
Let sit about 5 minutes to harden.
To add a star, use star sprinkles and a little bit of melted almond bark as "glue"
Hot Chocolate Bombs are now ready!
Add 1 hot chocolate bomb to a mug and pour hot milk over it.
Stir and enjoy.
You can use White Almond Bark colored with OIL BASED food coloring OR green candy melts.
Make sure to use OIL based food coloring if you're coloring the almond bark because regular food coloring can make it seize.
