This is a devil's food cake with mint buttercream frosting shaped like a slightly-wonky cat. This was more of an experiment based on what I had found in this cookbook. I'm fully aware that it is a bit busted, haha.
I assembled the pieces as laid-out by this illustration:
The cake was just a simple Devil's Food box cake mix.
The frosting is my own recipe... However, I would strongly advise using a chocolate frosting for any cake where you have to cut it into puzzle pieces, as this produces many crumbs which are hard to keep covered with white frosting! The trouble is, I'm not a big fan of chocolate frosting... And I happen to have a cat called Minty, hence the inspiration for a mint frosting.
