Preheat the oven to 350F.
In a bowl, mix together all-purpose flour, baking soda, and salt. Set aside.
In a large mixing bowl, mix together raw sugar and melted butter using an electric mixer. Then, add eggs, one at a time. Beat after each addition.
Add mashed bananas, low-fat yogurt, dark rum, and vanilla extract to the wet ingredients. Beat until completely combined. Then, add the dry ingredients. Mix on low speed until just combined.
Stir in ½ cup sweetened flaked coconut. Don't overmix the batter.
Grease a 9x5 inch loaf pan with non-stick cooking spray and line with parchment paper (leave some paper hanging on two sides, it will help to remove the Jamaican banana bread with rum from the loaf pan). Then, transfer the banana bread batter to the prepared loaf pan. Top with an additional 1 tbsp sweetened flaked coconut.
Bake in the preheated oven for 60 minutes or until ready. Check the readiness of the moist banana bread using a toothpick inserted in the center, if it comes out clean - the bread is ready. *If the banana bread is already golden brown, but still not ready inside, cover it with aluminum foil.
While the bread is baking, prepare the lime glaze. In a bowl, mix together powdered sugar and lime juice. Set aside.
Remove the banana bread from the oven and let it cool on a cooling rack. Then, remove the bread from the pan. Place on the cooling rack and drizzle with lime glaze. Let it cool completely. Then, slice and enjoy!
