This traditional Christmas cake was invented in France, where it is known as 'bûche de Noël'. It's basically a chocolate Swiss roll covered in chocolate ganache and make to look like a log. Quite easy to make and very impressive to look at.

Separate the eggs and whisk the whites to soft peaks.
In a separate bowl, beat the yolks until creamy. Add the sugar, breaking up any big lumps, and whisk until smooth. Now add the salt, spices, and cocoa powder. Whisk until you have a smooth paste. Now carefully fold in the egg whites, being very careful to not knock the air out of them.
Spoon the mixture into the prepared baking tin and spread it out to form a thin, even layer.
Bake for 20-30 minutes. When cooked, the sponge should spring back when you poke it with a finger.
When the sponge is completely cool, gently unroll it. Spread the buttercream all over the top of it and roll it up again. Put it in the fridge to chill.
With a fork, scrape lines in the ganache to make it look a bit like bark. Sift some caster sugar over the top and sides, and decorate with pine cones, holly, plastic robins or any other small Christmas trinkets that you happen to have lying around.
