Preheat your oven to 350°F (175°C) and grease the loaf pan with nonstick spray.

In a sauté pan, brown the stick of unsalted butter over medium heat until golden, about 5-7 minutes.

In a bowl, combine mashed bananas and eggs, mixing until smooth.

In a separate bowl, whisk flour, brown sugar, baking powder, cinnamon, salt, and nutmeg.

Fold the banana mixture into the dry ingredients and add the browned butter.

Pour the batter into the prepared pan and decorate with banana halves and brown sugar.

Bake for 70-80 minutes, or until a toothpick comes out clean.

Allow the bread to cool in the pan for 10 minutes before transferring to a wire rack.
