Moustache Cake

It was my littlest brother's birthday yesterday. This is his birthday cake. There's a bit of a running joke in our family about him and mustaches so when I saw a cake similar to this on pinterest I immediately thought of him.
It was surprisingly easy to do; bake a standard round cake (mine was 8 inches) then cut it in a yin-yang design. I traced the design freehand with a knife first then cut all the way through to the bottom of the cake when I was happy with the shape. 

Once they'd be cut I covered the shapes in a thin layer of icing. This is more professionally known as a crumb coat but I think Cake Boss' 'dirty icing' is a much better name.
Remember, one of them needs to be flipped over so that the final shape looks like a mustache. I forgot this. 

After the layer of dirty icing had set up in the fridge I used the remaining icing to completely cover the cake. A dragged a fork all over it to make it look 'hairy'. It's kinda gross describing a cake as hairy (finding a hair in my food literally makes my stomach turn and I can't eat any more) but that's what this cake is all about so go with it. Make it as hairy as possible.
