This Jack Skellington cake was easier than it looks. I baked two 9x13" cakes and one 8" round. I bought a huge strong piece of cardboard and covered it with Christmas paper to place the cake on. The round cake is the head. One of the 9x13" cakes is for the torso.
With a sharp knife I cut off the two corners at the top and I tapered it down to a thin waist. The other cake I cut out two arms and a neck. Once I had everything cut out and in place I made up a thin frosting of powdered sugar and milk to seal the crumbs and hold the cake in place.
After that dried I made up lots of buttercream frosting and frosted the head. I frosted the neck and a v-shape front of the vest in white. Then I switched to black frosting and made a jacket, making a lapel around the v-shaped white. I dipped the spatula in water and smoothed the frosting out.
Using black fondant I cut out eyes and nose and placed it on the face. Then I piped on a straight line of black frosting for the mouth and took a toothpick and ran it up and down through the line to make it look like stitches.
I took white frosting piped w/#3 tip to make the lines going in one way on the lapel and then on the jacket. The one button is a vanilla chip upside down.
His hands are cut out from a picture I printed from the internet on bones of the hands. I just taped them in place. I made the bat collar out of black construction paper then I piped on frosting and set it in place. I had some cake left over so I make a little area to write my son's name and Happy Birthday! He was quite impressed.
