With chocolate grahams these will knock 'em dead at your party! Start with any flavor cupcake baked in a green or dark wrapper. Add green icing, smoothing a path down the middle. Pipe fun Halloween messages like "RIP" or "BOO" on the top center of your chocolate-covered cookie tombstones. Sink each tombstone into its own cupcake, about half an inch along the back side, even with the centered smooth section. Crumble a few cookies into very small crumbs and dust them over the smooth section to mimic freshly-turned earth. Now you've got the tastiest cemetery around!
