Whisk together all batter ingredients (except oil) in a large bowl.
Slice bread. Dip several slices of bread into the batter and let soak for a few seconds on each side.
Heat oil in a large fry-pan on medium heat. Add bread and cook for 2-3 minutes on each side until golden brown. Once cooked, set aside and keep warm. Continue this process until all bread is cooked.
Peel bananas and cut in half lengthways. Heat large fry-pan on medium heat and place bananas cut side down. Sprinkle over brown sugar and cook for 7-8 minutes until they are a deep caramel colour and just cooked through.
Serve French toast with bananas and a generous topping of maple syrup, coconut chips and blueberries.
