Bake the brownies and let them cool completely. Bake the brownies according to package instructions. Let them cool completely- at least 2 hours- prior to decorating.

Decorate the Milanos to look like tombstones using the food writer. When the brownies are cool, use the food pen to write "RIP" or other spooky phrases on the cookies to turn them into tombstones. Then push the cookies down into the brownies so they look like a grave. You can do this evenly or more randomly depending on the look you are going for.

Finish the brownies by layering on the rest of the decorations. Add mounds of dirt around the graves by piling cookie crumbs around the cookie headstones. Then scatter the bone sprinkles throughout the graveyard and finish by adding some zombie hands. Finish by piping the green icing to make pumpkin vines around the edges of the brownies and adding some pumpkin candies throughout.
