I made this cake for a very good friend's October birthday, who is a huge horror and comic fan. This was made custom to look like him but you could tailor the look how you please. It was a surprise for him and he absolutely loved it.
Depending on your artistic skill, this could be hard or easy. I'm an artist, new to cake decorating and this is my 4th sculpted cake (self-taught) and I've been making cakes since August (and am absolutely in love with it!)
Total time spent on it from the start of baking to completion was about 12 hours over the course of 3 days. On one day I baked all the cakes and froze them. The next I made the tombstone and the final day I make to zombie and finished it up.
The tombstone is red velvet cake covered in fondant. The zombie is red velvet cake covered in fondant. The fingers are all fondant and the grass/ground is fondant. The dirt is made from chocolate sandwich cookies (minus their cream layer) and ginger snaps ground up in the food processor. It was hand painted with gel food colorings mixed like watercolors (but not with water.)
