1. In a large bowl, place all of your cake ingredients and use an electric whisk to mix together until smooth and creamy.

2. Grease and line a 8in round loose bottomed cake tin, pour in your cake mix and bake in an oven preheated to gas mark 4/180c for 1 hour-1 hour 15 mins - until brown and a skewer pressed into the middle comes out clean.

3. Remove from the oven and allow to go cold in the tin, we need it in the tin to pour the ganache on top. This will take a good few hours, though it doesn't need to be completely cold before you add the ganache.

4. When the cake it cooled, no more than aired to the touch, it's time to add the ganache.

5. Place the cream in a saucepan and warm though, you don't want it boiling, just before it reaches that point is fine.

6. If using blocks of chocolate, roughly chop and add into the cream (I used Bourneville buttons so no need to chop), stir until all the chocolate has melted and you have a thick glossy ganache.

7. Allow to cool for 10 mins, then pour on top of your cake in the tin, level out and then leave to go cold, I chilled mine overnight but it will need leaving a minimum of 6 hours for the ganache to set enough to remove from the tin.

8. Once the ganache is set, remove your cake from the tin.

9. Now it is time to decorate with marzipan, feel free to do whatever patterns or designs you want, traditionally, marzipan fruits are used but you can make any marzipan decorations you feel like. I did a simple holly and berry marzipan topping by colouring about 1/8th pk of marzipan green and another 1/8th red, then cut round a print out of a holly leaf and rolled balls which I then pressed onto of the cake, using a little water to stick where needed.

10. Slice up and serve on its own or with a drizzle of cream! This also freezes well too, simply slice and freeze and naturally defrost as wanted.
