What you need:

8 ounces (1 1/4 cups) bright white candy melting wafers

3 cups chocolate candy rocks

One 9-by-13-inch chocolate cake

One 14.1-ounce package digestive biscuits

Neon green food coloring

3 crisp ladyfinger cookies

Tools:

Disposable piping bag

Skeleton bone candy mold

One 2-gallon or larger glass jar (or other clear container) with a lid

Food processor

Parchment paper

Food coloring marker

Shovel spoons

What to do:

Microwave 1 cup (about 6 ounces) candy melting wafers in a microwave-safe bowl at 100 percent power in 30-second increments, stirring in between each, until the candy is melted and smooth.

Transfer to a disposable piping bag with a small hole snipped in the end. Pipe the candy into the cavities of a skeleton bone candy mold. Gently tap the mold on a work surface to remove the bubbles, then refrigerate until firm, 5 to 7 minutes.

Turn the candy bones out of the mold onto a work surface and cast the remaining melted candy in the same manner; refrigerate. Let the bones come to room temperature before using.

Place an even layer of chocolate candy rocks approximately 3 inches deep in the bottom of a 2-gallon or larger glass jar with a lid.

Crumble the chocolate cake into a large bowl.

Then layer the crumbs on top of the chocolate rocks. (This will be the "dirt" where the candy bones are buried.)

Place the candy bones in the chocolate cake dirt, being sure to position lots of bones against the glass so they are visible through the jar.

Grind the digestive biscuits in a food processor until fine. Add neon green food coloring and process until the crumbs turn bright green.

Layer the cookie crumbs on top of the chocolate cake crumbs.

For the cookie tombstones, microwave the remaining 1/4 cup candy melting wafers in a microwave-safe bowl at 100 percent power until smooth and melted.

Lay a sheet of parchment paper over a work surface. Break the ladyfingers in half. Dip the rounded ends of each ladyfinger in the melted candy and place on the parchment to set.

When the candy is set, use a food coloring marker to write messages on the tombstones.

Place the tombstones upright in the green crumbs.

To serve, dip a large serving spoon down through the layers to retrieve some of each layer, and remove to individual serving cups. Add shovel spoons to each cup.
