I've been having some fun decorating my favourite chocolate cake...
All it takes is a stencil and some icing sugar.
The first one is just a doily (you can get those at the $2 shop) i cut a heart out of the centre of mine and then sifted the icing sugar on top.
The second one is a clear plastic sheet (ie Old OHP paper). The great thing about this is you can create whatever design you want! I'd previously used that one as a paint stencil so it's a bonus that it worked for cake decorating to.
So go on, next time you're invited out for dinner offer to bring the cake and have a go at some alternative decorating.
