Preparation
Line the base of the air fryer with an air fryer liner or baking paper and grease with the butter. Preheat the air fryer to 180°C. In a bowl, use your hands to gently crush the cornflakes. Toss with the melted butter and 1 tsp light brown sugar.
Whisk together the egg, milk, cinnamon and remaining sugar in a shallow dish until well combined. Add the bread to the egg mixture and soak for 30 seconds. Turn and soak for another 30 seconds. One at a time, press one side of the cornflakes to coat for crunch. Transfer to the air fryer, cornflake side up, and air fry for 6 minutes. Transfer to a serving plate and repeat with the remaining bread, egg mixture and cornflakes.
Halve the French toast into triangles and dollop on the yoghurt for creaminess, drizzle with the maple syrup for sweetness and finish with the berries.
Transform a near-empty box of cereal and some stale bread slices into this unexpected brunch showstopper.
