Preheat oven to 350 degrees.

In a large bowl, combine flour, baking soda and salt. In a separate bowl, mix butter and brown sugar. Once combined, stir in eggs and mashed bananas until well blended. Stir banana mixture into flour mixture until combined.

Optional: Add chocolate chips, raisins or nuts to the mixture

Lightly grease a 9x5in loaf pan. Pour batter into pan.

Bake in oven for 55-60 minutes, until a toothpick inserted into the center of the loaf comes out clean.

Let bread cool for 10 minutes before removing from loaf pan.
