Method

Preheat the oven to 170°C, and line your loaf tin of choice.

Add all the dry ingredients to a bowl, mixing to combine, then add all the wet to another bowl, mixing well (apart from the pumpkin puree).

Add the wet to the dry ingredients, then add your pumpkin puree, then mix the cake batter – don’t mix too well here though – you want there to be lumps of flour left in the batter, but not too many.

Transfer just less than half of the batter into another bowl, stirring through 1 tbsp of cocoa powder.
Start putting your batter into your prepared loaf tin, 2 tbsp at a time, so you get a marble pattern (as shown in the video), then bake for around 1 hour, or until risen and golden brown.

Leave the cake to cool for at least 10 minutes before removing from the tin, then slice and serve.
