To prepare your molds, use a paper towel or clean kitchen cloth to wipe the inside of the silicone molds. This will allow your chocolate sphere to have a shiny coat on it.
To make removing the chocolate shells from the mold easier, you can cut each section of the mold so you have individual pieces. This can give you more control, but is 100% optional and a personal choice! See the photo below.
Remove 20 melting wafers from the package and set them aside. These will become the ears.
Line a cookie sheet (or tray or plate) with wax paper and set it aside.
Pour the chocolate wafers into a microwave-safe bowl, and microwave for 45-second intervals, stirring each time until the chocolate is completely melted and smooth. Alternatively, follow the directions on the package.
Spoon about 1 to 2 tablespoons of the melted candy into one of the mold cavities.
Carefully swirl the melted chocolate to completely coat the inside of the mold,
Lightly shake the extra chocolate back into the bowl.
Repeat steps 6-8 for as many chocolate bombs as you are making. You will need two halves per bomb.
Place the coated molds into the fridge for 5-10 minutes to set.
Remove from the fridge and gently peel the silicone mold back away from the hardened chocolate shell and carefully place the mold onto the cookie sheet. Repeat with all of the molds.
To build the cocoa bombs, place about 1 tablespoon of chocolate hot cocoa powder into one half-shell.
Sprinkle in a few mini marshmallows.
Pour in some sprinkles - about ½ teaspoon.
