Zombie Graveyard Cake

Ingredients

• 1 cup butter (2 sticks)
• 2 cups chocolate wafers such as nabisco famous crumbled
• 6 cups powdered sugar 
• 12 servings grands flaky refrigerator biscuits 
• 0.3 cup cup heavy whipping cream (you may not use all of it)
• 1 drops drop natural food coloring green
• 12 servings betty writing gel 
• 1  round cake 
• 1 teaspoon vanilla extract 

Equipment

• mixing bowl
• toothpicks

Directions

1. Prepare the frosting: Cream the butter in a mixing bowl fitted with the paddle attachment, mixing on medium speed until smooth and creamy in texture.
2. Add 4 cups of the confectioners' sugar, half of the cream, and the vanilla extract. On medium speed, beat until smooth and creamy, 3 to 5 minutes.
3. Gradually add the remaining sugar, 1 cup at a time, beating well after each addition (about 2 minutes), until the icing is thick enough to be of good spreading consistency. You may find that you don't need all of the sugar. If desired, the remaining cream can be used to make the frosting easier to spread.
4. Add the food coloring in last, mixing until the coloring is even.
5. Apply a small quantity of the frosting to the top and sides of the cake to be used as a crumb coat. Chill the cake for 20-30 minutes or until the crumb coat layer is firm.
6. Apply the rest of the frosting to the cake, applying most generously to the top of the cake, but putting enough on the sides of the cake so that there is an opaque layer covering the cake.
7. Immediately after frosting the cake, press the crumbled chocolate wafer cookies on the sides of the frosted cake. If you'd like, sprinkle a few crumbs on top, too.
8. Prepare your "graves". On the top half of a sandwich cookie (I used Vienna fingers for their oblong shape), write "RIP" or a spooky message.
9. Let the writing icing set for a couple of minutes, and then press the cookie into the cake until half of it is submerged. It will resemble the shape of a grave in the cake. Repeat to form as many gravestones as you'd like.
10. Create several zombie cake picks by cutting out these printable illustrations and taping them (on the back side) to toothpicks. Insert zombie picks into cake. Finish the cake by adding whatever other spooky garnishes you'd like (meringue skulls, candy mushrooms, et cetera).
