Pre-heat oven to 200˚C (fan). Mix the peanut butter, soy sauce, malt extract and honey in a large microwavable bowl and warm for around 30 seconds in the microwave. Mix together until smooth and place to one side. Place the wings on an oiled tray and bake in the oven for about 15 minutes then remove and tip the wings into the bowl with the malted peanut sauce and coat thoroughly. Tip them back onto the tray and return to the oven for a further 15 minutes or until sticky and caramelised. Serve with a good quality coleslaw.
