Preheat oven to 350 degrees F. Peel and cut 2 plantains into small pieces and add to a large bowl. Using a fork or potato masher, mash plantains.
To bowl, add butter, eggs, sugar, cinnamon, vanilla and 1/4 cup coconut. Using an electric mixer, mix to combine.
In a medium bowl, combine flour, baking powder, baking soda and salt. To bowl with plantain mixture, alternate adding flour mixture and sour cream. Beat until well combined. Fold in chocolate chips, if using.
Pour batter into a greased loaf pan. Sprinkle top with remaining 1/4 cup coconut. Peel remaining plantain and slice in half lengthwise. Place on top, gently pressing into batter. Bake 50 to 55 minutes, until toothpick inserted in center comes out clean. Let bread cool 10 minutes in pan. Transfer to a wire rack to cool completely.
