For the vanilla cake
- 175g butter, softened
- 175g caster sugar
- 3 eggs
- 175g self-raising flour
- 2 tsp vanilla extract
For the red velvet cake
- 200g plain flour
- 25g cocoa powder
- 1tsp baking powder
- 100g butter, softened
- 175g caster sugar
- 2 eggs
- 1 tsp vanilla extract
- 1 tbsp red food colouring (bake stable)
- 150g buttermilk
- 1 tbsp lemon juice
- 1 tsp bicarbonate of soda
For the icing
- 100g butter
- 100g cream cheese
- 400g icing sugar, sifted
- 800g natural marzipan
Preheat the oven to 180C. Line 2 x 900g loaf tins.
For the vanilla cake, cream the butter and sugar until light and creamy, then add the eggs one at a time. Mix really well, until everything is incorporated.
Stir in the flour and vanilla and then beat well, until fluffy. Scrape into one of the tins and get the cake into the oven. Bake for 25-30 mins, until springy.
Meanwhile, make the red velvet cake. First off, stir the flour, cocoa and baking powder together. Set aside. Cream the butter and sugar together and then mix in the eggs, one at a time. Next, stir in the vanilla and red colouring. Add the flour and cocoa mix, along with the buttermilk, and beat well to combine.
Stir together the lemon juice and bicarbonate of soda, pour into the cake batter and mix well. Scrape the mixture into the second tin and bake for 25-30 mins. Let both cakes cool completely.
Make the icing by beating together the butter and cream cheese, then adding the icing sugar. This is likely to create big clouds of sugar dust, so go carefully at the offset!
Take each cake and slice off a hefty bit from the top and cut a sliver from the bottom and sides, resulting in a neat rectangle. Cut each cake in two lengthways so you end up with four pieces of cake, each with a square end of around 5cm.
Sandwich two opposite colours together side by side with some of the icing, then spread more icing over the top. Place the remaining two pieces of cake on top, alternating the colours.
Dust your work surface with icing sugar and roll out the marzipan until it is about the size of an A4 piece of paper. Spread a rectangle of icing on to the marzipan, about the size of the cake.
Sit the cake on top and ice the very top. Carefully lift the marzipan up over the cake, using the palm of your hand to support the sides, and then press it to the cake. Trim any excess so the seam is not too bulky. Roll the cake over so the seam is on the bottom, then trim any excess marzipan from the ends for a neat finish.
It is now ready to serve, in thick slices preferably, with a cup of tea!
