Preheat the oven to 350°. Grease a 10" x 5" x 3 ½" loaf pan and set aside. If you use a smaller pan, fill until the batter reaches 3/4-1 inch below the top edge. Excess batter can be used for muffins or mini-loaves.
In a large bowl, whisk together the sugar, flour, baking soda, nutmeg, salt and baking powder.
In a medium bowl, beat the eggs and the mashed bananas together. Pour the wet ingredients over the dry ingredients and mix together until the dry ingredients disappear. Stir in the melted butter until fully incorporated. If using, fold in dried fruit and nuts.
Pour the batter into prepared pan* Bake until golden brown and a cake tester inserted in the center of the loaf comes out clean, about 1 hour and 10 minutes. Check loaf halfway through, if the crust is browning too quickly, cover with foil. Allow to cool for 20 minutes before slicing.
*Optional: Mix 1 teaspoon cinnamon with 2 tablespoons granulated sugar. Wet finger tips and mix sugar mixture until it clumps. Sprinkle evenly over top of batter. Or use your favorite streusel topping.
