Preheat oven to 350 degrees F (175 degrees C). Lightly grease a 9x5 inch loaf pan.

In a large bowl, combine flour, baking soda and salt. In a separate bowl, cream together butter and brown sugar. Stir in eggs and mashed bananas until well blended. Stir banana mixture into flour mixture; stir just to moisten. Pour batter into prepared loaf pan.

Bake in preheated oven for 60 to 65 minutes, until a toothpick inserted into center of the loaf comes out clean. Let bread cool in pan for 10 minutes, then turn out onto a wire rack.

Add a pad of butter to each slice while (best when still warm) before serving!
