Ingredients

125g unsalted butter
100g peanut butter (we used crunchy)
150g caster sugar, preferably golden
1 tsp vanilla extract
2-3 ripe medium bananas, mashed (about 200g peeled weight)
2 medium eggs, beaten
175g plain flour
2 tsp baking powder
½ tsp bicarbonate of soda
2 tbsp cocoa powder
25g peanuts (we used salted)
25g milk or dark chocolate chunks

Step by step

Get ahead

The cake keeps well for a week in an airtight container, or can be frozen for up to a month.

Preheat the oven to 170°C, fan 150°C, gas 3. Grease and line a 900g loaf tin.
Melt the butter in a pan, then remove from the heat, stir in the peanut butter until combined, then pour into a large mixing bowl and set aside to cool slightly.
Mix the sugar, vanilla extract and mashed banana into the butter mixture, followed by the beaten eggs. Sift in the flour, baking powder, bicarbonate of soda and ½ teaspoon salt, and stir to combine thoroughly.
Working fairly quickly now that the raising agents have been activated, scrape about half the batter into another bowl and mix in the cocoa powder. Spoon alternating dollops of the light and dark cake batters into the loaf tin, then use the handle of a spoon to run a zig-zag line through the mixture, marbling the colours together.
Scatter the peanuts and chocolate on top then bake for about 1 hour or until a skewer inserted in the centre of the loaf comes out clean.
Cool in the tin for 30 minutes before turning out to cool fully on a wire rack. Slice to serve.
Tip Make it gluten-free
