Ingredients (serves 12)
- 100g butter
- 150g smooth peanut butter
- 1 medium egg
- 150g caster sugar
- 1tsp vanilla extract
- 50g banana chips, chopped into small chunks
- 50g white chocolate, chopped into small chunks (plus a little extra melted for drizzling)
- 125g plain flour
- rectangular baking tin (I used 26cm x 20cm)
- grease proof baking paper
- Preheat oven to gas 5/375F/190C.
- Line the tin with baking paper (or just grease it lightly - I find baking paper makes it easier as you can just lift it out to cool).
- In a large mixing bowl (or using a stand mixer) cream together the butter and peanut butter until well combined.
- Mix in the egg, caster sugar, and vanilla until the mixture is a runny consistency.
- By hand, mix in the banana chips and chocolate.
- Again, by hand, mix in the flour until thoroughly combined; it should be a fairly stiff mixture.
- Pour into the baking tray, smooth the top, and bake for 30-35 minutes, or until a cocktail stick inserted comes out clean (or with a few crumbs on).
- Leave to cool, drizzle with melted white chocolate, then cut into 12.
