Put the beans, the coconut milk and half the milk in a pot and bring to a boil. Add the rest of the milk, sugar, raisins and sweet potatoes and let boil medium heat for 10 minutes. Stir regularly to avoid sticking. Add the rest of the ingredients and boil to the desired consistency.
Spread butter on the cassava bread, sprinkle with salt and put in the oven until it turns golden brown.
Serve the beans chilled with the cassava on the side. Put cookies on top of the beans.
