Preheat the oven to 350°F. Grease a 10" x 5" x 3 ½" loaf pan and set aside.
In a large bowl, whisk together the sugar, flour, baking soda, nutmeg, salt and baking powder.
In a separate large bowl, beat the eggs and combine with the mashed bananas. Pour the wet ingredients over the dry ingredients and mix together until just combined. Stir in the melted butter until fully incorporated.
Pour the batter into the prepared pan and bake until golden brown and a cake tester inserted in the center of the loaf comes out clean, about 1 hour and 10 minutes. Allow to cool for 20 minutes before turning the bread onto a wire rack to cool.
Notes
I like to add a crunchy cinnamon-sugar topping to this bread. To do this, mix together 3 parts sugar and 1 part cinnamon (by volume) and sprinkle generously over the batter before baking.Makes 1 10x5-inch loafRecipe from Dominique Ansel.
