Preparation

Step 1Preheat oven to 350° and spray four 9" cake pans with cooking spray. In two large bowls using a hand mixer, prepare both chocolate and vanilla cake batter.Step 2Divide batter among prepared pans, two chocolate and two vanilla, and bake until a toothpick comes out clean, 30 minutes. Transfer to a wire rack to cool completely.Step 3Make frosting: In another large bowl using a hand mixer, beat together butter and half of the powdered sugar until smooth. Beat in the milk, vanilla, pumpkin spice, and the rest of the powdered sugar until light and fluffy. Stir in food coloring until frosting is a bright, jack-o-lantern orange.Step 4Make ganache: In a small saucepan over low heat, heat heavy cream just until it bubbles. Place chocolate chips in a medium, heatproof bowl and pour over hot heavy cream. Let sit 2 minutes, then whisk until smooth.Step 5Assemble the cake: Level cake layers with a large serrated knife. Place a dab of frosting on a cake plate or serving platter and top with the first vanilla cake layer.Step 6Top cake with 1 cup frosting and smooth into an even layer. Add the first chocolate cake on top of that, frost with another cup of frosting, then repeat with remaining vanilla and chocolate layers. Frost outside of cake with remaining frosting.Step 7Drip ganache down the sides of the cake, then pour the rest on top of cake and smooth out with an offset spatula.Step 8Decorate the cake: Create a graveyard scene by placing ghost peeps on skewers to stick out of cake, break Milanos in half and place on cake like graves, surrounded by Oreo “dirt”, sprinkles, candy corn and pumpkins, and candy eyeballs.
