This instructable is step by step, and shows how to cut the cake-pieces into a cow :)
Unfortunately i managed to delete some images from covering and painting the cow, but I think you get it anyway!
The cake is covered with Marshmallowfondant
I prefer to paint my cakes - the colors used were:
sugar-flaire colors thinned with vodka
"chestnut" for the body
"liquorice" for the hoof and nose-holes
a little bit "christmas red" for the nose and udder
"party green" for the cake board
Step 1: Layout
laying on the ground - look closely on the anatomic.
It doesn't hurt to have a printed copy by your working space.
