In a large bowl, combine the mashed plantains, flour, sugar (if using), baking powder, salt, and ground nutmeg. Mix well until all ingredients are evenly incorporated. You can also add finely chopped onions and peppers if you like for extra flavor.
Heat vegetable oil in a deep frying pan or pot over medium heat. The oil should be enough to submerge the fritters.
Drop spoonfuls of the batter into the hot oil. Fry in batches, making sure not to overcrowd the pan. Cook each side for about 2-3 minutes or until golden brown and crispy.
Use a slotted spoon to remove the Kakro from the oil and drain on paper towels.
Enjoy your meal!
