Preheat oven to 190°C.
Cut the bread into chunks and place into a small baking dish.
Mix the protein powder with milk until smooth (skip if not using).
Add the mashed banana, egg, cinnamon and milk mixture into the dish.
Mix well so the bread is fully soaked.
Top with chocolate chips and sliced banana.
Bake for 15–20 minutes, until set and lightly golden.
Enjoy warm with yoghurt and a drizzle of honey.
