ASSEMBLY & FINISHING

• Grease the cake tin and line with baking paper.
• Fill one piping bag with the vanilla batter and another with the cocoa batter.
• Fill the bottom of the cake tin with one third of the vanilla batter, then add half of the cocoa batter lengthways into the middle of the vanilla mixture.
• Pipe in another third of the vanilla batter and put the rest of the chocolate batter in its middle.
• Finish off by layering the final third of the vanilla batter across the top. Use a knife dipped in melted butter to make a split in the cake’s surface to help it rise in the oven.
• Bake at 300°F (150°C) for approx. 60 minutes. Check it is fully baked by piercing the cake with a knife – if it comes out clean, the cake is done.
• Turn out onto a rack and leave it on its side for 10 minutes so it keeps its shape.
