1 teaspoon baking soda
1 cup (2 sticks) unsalted butter, melted and cooled
2 teaspoons pure vanilla extract
2 cups sugar
3 large eggs
2 1/2 cups mashed ripe banana (about 3 large)
1 can (8-ounces) crushed pineapple, drained
1 1/2 cup unsweetened desiccated coconut
Preheat oven to 175c degrees with rack in center. Line cupcake pan with paper liners; set aside. In a medium bowl, whisk together flour, baking soda, cinnamon, and salt; set aside.
In the bowl of an electric mixer fitted with the paddle attachment, beat butter, vanilla, and sugar until combined, about 2 minutes. Add eggs one at a time, incorporating each before adding the next. Beat at medium speed until mixture is pale yellow and fluffy, about 3 minutes.
In a medium bowl, stir together banana, pineapple and coconut. Add to egg mixture, mixing until combined. Stir in flour mixture.
Divide batter evenly among liners, filling about 2/3 full. Bake, rotating pans halfway through, until golden brown and a cake tester inserted in the center comes out clean, 25 to 28 minutes.
