Banana coconut muffin

3/4 cup all-purpose unbleached flour
3/4 cup whole wheat flour
1 teaspoon baking powder
1/4 teaspoon salt
3 very ripe bananas, mashed
1 stick (1/2 cup) unsalted butter, melted
1/2 cup sugar
1 large egg
1 tbsp milk or soy milk
1 teaspoon vanilla
1/2 teaspoon cinnamon
1/4 teaspoon nutmeg
3/4 cup sweetened flaked coconut

Put oven rack in middle position and preheat oven to 375°F. Line 8 muffin cups with liners.

Whisk together flour, baking powder, spices and salt in a bowl. Whisk together bananas, butter, sugar, egg, vanilla, milk or soy milk and 1/2 cup coconut in a large bowl until combined well, then fold in flour mixture until flour is just moistened.

Divide batter among lined muffin cups and sprinkle with remaining 1/4 cup coconut. Bake until muffins are puffed and golden, about 25 minutes. Transfer muffins to a rack and cool slightly.
