First put the oat flakes in a blender and mix until they are fine, i.e. have a floury consistency. Then cut the banana into small pieces, add the milk and cinnamon and mix again.
Heat a little oil in a pan and bake about 4 small pancakes in it.
Now mix all the ingredients for the chocolate sauce and pour over the baked pancakes.
Garnish the pancakes with fruit. Bananas, berries and mangoes go particularly well with it.
