How to make a Christmas Faultline Cake

How to make a Christmas Faultline Cake

Cake designer Samantha Gojak from Wicked Cakes shows us how to make this amazing show-stopper Christmas cake complete with an arctic geode scene hidden in the faultline of this cake.

The cake-dwelling animals are made using three of our most popular winter moulds – Penguin Family Mould, Polar Bear Family and Icicles Mould.

For the cake itself, we suggest a traditional Christmas fruit cake recipe, but you could make a simple vanilla or chocolate cake instead. You will need to make two 6 inch cakes and a 4 inch cake to follow this design.

Hello! I don’t make cakes, but I do decorate recycled items, like tin cans…I can picture doing this with cans to make neat storage that looks like a cake…and yes, I have the polar bear molds, I think I need to get the penguin set as well. Very cute! Yes, I am going to have to get back into making my ‘cake cans’ once again. Blessings!

Would love if you could make an igloo mould, seal, as well as male and female Eskimos. I think of all the creative projects that could be made along with the penquin, polar bear and icicle moulds.
