As far as decorative Halloween cakes go, this one is the easiest by far. Eerie and darkened with black cookie crumbs that look like soil, our Graveyard Cake might just be a must Halloween decoration for your table.In addition to being festive, our recipe requires no homemade components. Instead, we use a box of Devil's Food cake mix to make the batter for the cake layers, we use a can of chocolate frosting for the filling and outside of the cake, and we use Oreo cookies and Milano cookies for decoration. All of this means that you don't have to fuss with from-scratch cake batters and buttercreams, giving you more time to plan and decorate your home for a Halloween party. The face of each Milano cookie has gravestone messages written in black decorating icing before being pushed into the surface of the cake to give the illusion of gravestones. Oreo cookies are crushed and pressed against the sides of the cake and sprinkled in mounds on top of the cake to look like the freshly turned soil of a grave. This simple and cute cake takes no more than 30 minutes of hands-on time, so get spooky and decorate this graveyard in a flash.
