Preheat the oven to 400°F.
In a small blender, pulse the oats, baking powder, chia seeds, banana, cocoa powder and milk until smooth.
Pour most of the batter into a ramekin, reserving around 2-3 Tbsp of the batter. Scoop the caramel sauce into the centre of the ramekin, then top with the reserved batter.
Sprinkle the top with the chocolate chips and sea salt.
Bake in the preheated oven for 20 minutes. Enjoy warm.
