Prepare white chocolate skull and crossbones first (see below for instructions)

Prepare cupcakes according to package instructions. Cool completely.

Prep frosting: Combine 1/4 tsp of moss green gel food coloring to vanilla frosting and set aside.

Place prepared cookie dough in a medium bowl and add 1/2 tsp moss green gel food coloring and mix until well combined.

Scoop about 1 tsp of cookie dough onto a parchment lined cookie sheet. Use a fork or butter knife to press dough flat into irregular shapes.

Bake for 10 minutes at 350 degrees. Cookies will have a slightly browned bottom which is what you want to add depth of color to your mossy cookies. Cool cookies and set aside 24 small cookies to top your cupcakes with.

Crumble the remaining cookies into a medium bowl and set aside. This will be used to top your cupcake frosting and to add mossy texture to the sugar cookie topper.

Frost cupcakes

Dip frosted cupcake into crumbled cookies to create a mossy top.

Lightly frost the bottom of one of the small sugar cookies that you set aside and then add a small dollop of frosting to the other side of the cookie to act as a glue to hold the cookie to the top of the cupcake.

Now sprinkle cookie crumbs over the slightly frosted cookie bottom to complete the mossy look.

Garnish with skull and crossbones, securing with a small amount of frosting.

Melt chocolate according to package directions and transfer into a piping bag or a plastic ziplock bag with the corner cut off. Pipe melted chocolate into molds and tap the bottom of the molds on counter to settle chocolate and remove air bubbles and empty space. Place filled molds in the refrigerator and let set for 15 minutes or longer as needed. Remove skull and bones from the molds and set aside. Don't worry if the small crossbones break, they can still be used with the skulls. Repeat until you have 24 skulls and 48 bones.

Aging bones: In a small bowl, add 1/2 tsp. cocoa and 1T vodka and mix until combined. Use a paint brush to paint the chocolate skulls and bones with the cocoa vodka mixture to age the bones. The vodka will evaporate and leave the cocoa behind creating an aged look of the bones. Set aside until ready to use.
