DH wanted us to do an Olaf cake for DD's Frozen party, but he was thinking more regular snowman - it's easy enogh to do two half circle cakes and join them, then again and put on top. But I said no unless it looks like real Olaf, feet and all lol.

I think the easiest option would be to make round/square/rectangle cakes and cut out the shapes. So it's more 2D than 3D, he's lying flat on the board instead of standing up. That's how I did the Iggle Piggle cake.
