Bolo de aipim ( macaxeira ou mandioca)

750g cassava (yuca or manioc) 3 whole eggs 3 heaping tablespoons of butter or margarine 1 1/2 cups of sugar (250g) A pinch of salt 350ml milk (I made it with dried coconut) 100ml grated coconut (I used the coconut I made the milk from, but you can use store-bought coconut milk) 2 tablespoons of grated cheese (I didn't use it because I didn't have any) Cut the cassava into cubes, and remove the fibrous part. While baking, add coconut milk once or twice.
