Preheat the over to 180c
In a blender, combine the oats, milk, banana, egg, honey, baking powder, salt, and 1 teaspoon of Nutella. Blend until well combined - around 50 seconds.
Pour the baked oats batter into two greased ramekins and spoon 1 teaspoon of Nutella into the middle of each one.
Carefully pace on a baking tray and bake for 30 minutes.
Remove from the oven, let cool for a few minutes, and enjoy!
You can even add a dollop of Greek yoghurt on top and some extra honey.
