Pre-heat your Weber BBQ on high for 10 minutes. Line a loaf tin (~21cm) with baking paper and spray lightly with cooking spray.

Combine dry ingredients (flours, cinnamon and sugar) in a large bowl. Add the wet ingredients (milk, mashed bananas, eggs and butter) to flour mixture and stir until combined.

Turn the Weber down as low as it will go. Pour mixture into the loaf pan, and place the loaf tin on a trivett with a heat diffusing tray underneath.

Cook for 50 minutes or until a skewer stuck in the centre of the loaf comes away clean. Serve warm and enjoy!
