Preheat oven to 160°. In a saucepan, melt the butter with the maple syrup. Set aside.
In a bowl, mix the oats with the coconut, flour and cane sugar. Add the melted butter to the maple syrup and mix well to obtain a homogeneous mass. Pour into a square or rectangular pan lined with baking paper, press down well with your fingers and bake for 20 minutes. Let cool.
Melt the chocolate and butter in a double boiler, cut into small pieces. Once the mixture is smooth and shiny, pour it over your cooled oatmeal. Leave in the fridge for 2 hours, if you want the chocolate to set. If not, you'll have a lot of it, but it's good too.
