Preheat oven to 350ºF. Grease a loaf pan and set aside.

Combine 1/2 cup of the golden sugar with 2 teaspoons of cinnamon. Sprinkle a few teaspoons of the cinnamon-sugar mixture around the inside of the loaf pan, coating it as best as possible. Set aside.

In a large bowl, whisk together the mashed bananas with melted butter, stirring to combine.

Whisk in the remaining 1/2 cup of sugar, the eggs, greek yogurt, and vanilla.

In a separate bowl, combine the flour, baking soda, and salt. Fold the dry ingredients into the wet.

Pour half of the batter into the prepared loaf pan. Sprinkle half of the remaining cinnamon-sugar mixture over the batter. Pour the rest of the batter on top and repeat with remaining cinnamon-sugar.

Bake for 60 minutes, or until a knife inserted in the center comes out clean. Allow to cool for 15 minutes before removing from loaf pan and serving!
