Heat oven to 350 degrees. Grease sides of an 8 x 4 inch loaf pan and line long sides and bottom with a piece of parchment paper (this makes removing the loaf easy).
Combine dry ingredients in a large mixing bowl.
Using a smaller bowl, mix all the wet ingredients together.
Pour the wet ingredients into the dry ingredients and stir until just combined and no flour lumps remain.
Spread batter into prepared pan and bake for 50-60 minutes, or until a toothpick in the center comes out with just a few crumbs.
Cool 20 minutes in the pan and then remove to a wire rack to cool completely.
For Optional Glaze:
Whisk all ingredients in a microwave safe bowl (or a small saucepan).
Heat 45 seconds to 1 minute, stirring at the halfway mark, until thickened a bit (if using saucepan, heat to simmering and cook until just slightly thickened.
Cool a few minutes (it will thicken as it cools as well) before pouring over the loaf.
While glaze is still wet, sprinkle with coconut and press in lightly to help it stick.
Notes
*Melted butter can be substituted for the coconut oil if desired.
