A Wave from the Grave: Cake Idea
I originally saw this on a blog called Desserts by Candy. You can find the entire from-scratch cake recipe there. Since I rarely bake from scratch (I'm a cooker, not a baker), my interest is in how she does the fingers.
To make the fingers, shape the marzipan into five logs of vary length and score lines with a knife to make knuckles. If the marzipan is too sticky to work with, dust some icing sugar on your palm. Press a sliced almond to one end to make the finger tip and adhere with some left over chocolate glaze. Adhere the finger to the cake with more left over chocolate glaze and prop them up with toothpicks if necessary. Sprinkle some chocolate cookie crumbs around the fingers to make dirt.
Just for reference, she used 100g of marzipan. If you don't like marzipan, you could create the fingers using fondant.
If you want your cake to be more colourful, consider creating grass around the mound of dirt and on the sides of the cake. Use vanilla icing and add a few drops of green food colouring before applying it.
I think this will be gracing my table this Halloween, and I will be sure to post about it.
