Preheat the oven to 350°F. Spray a standard 9x5 inch loaf pan with nonstick baking spray and set aside.
In the bowl of an electric mixer, cream the granulated sugar and softened butter on high speed until light and fluffy. Scrape the bowl and mix in the bananas and eggs.
With the mixer on low, slowly add the flour, salt, baking soda, and baking powder. Scrape the bowl again and mix in the shredded coconut.
Scoop the batter into the prepared loaf pan and bake for 45-60 minutes, or until a wooden skewer inserted into the center comes out clean.
Allow the banana bread to cool in the pan for 10 minutes, then transfer it to a cooling rack set over a piece of wax paper.
*Additionally this is completely optional. But we have made it with or without the glaze. Either way it good.
While the loaf is cooling, whisk the powdered sugar and rum together until smooth, if too thick add more rum. Of too thin add more powered sugar,
