2 1/4 cups all-purpose flour
3/4 teaspoon double-acting baking powder
1/2 teaspoon baking soda
1 teaspoon salt
1 1/2 sticks (3/4 cup) unsalted butter, softened
1 cup firmly packed light brown sugar
1/2 cup granulated sugar
1 1/2 teaspoons vanilla
3 large eggs
1 tablespoon freshly grated lemon zest
1 1/3 cups mashed ripe banana (about 3 large)
3 tablespoons sour cream
3/4 cup chopped macadamia nuts
1 cup sweetened flaked coconut, toasted lightly and cooled

Into a bowl sift together the flour, the baking powder, the baking soda, and the salt. In a large bowl with an electric mixer cream the butter with the sugar, beat in the vanilla, the eggs, 1 at a time, the zest, the banana, and the sour cream. Add the flour mixture, beat the batter until it is just combined, and stir in the macadamia nuts and the coconut. Pour the batter into a buttered and floured 9 by 5 by 3-inch loaf pan and bake the bread in the middle of a preheated 350 degree F. oven for 40 to 50 minutes, or until a tester comes out clean. Cool the bread on a rack. Cooled bread can be wrapped well in plastic wrap and foil, chilled for 1 week or frozen for 1 month.
