Preheat the oven to 350°F, grease a 9×5 inch loaf pan with softened butter, and set it aside.

In a large mixing bowl mash the 3 large overripe bananas with a fork.

Then add the ½ cup melted butter and whisk until combined.

Add ⅔ cup sugar, 2 eggs and 1 tsp vanilla extract and stir together until combined.

Sift together the dry ingredients (2 cups all-purpose flour, 1 tsp baking soda, ½ tsp baking powder, and ¼ tsp salt). Using a spatula, fold it in.

Fold in the ½ cup of chopped walnuts.

Pour the batter in a pre-greased 9×5 inch loaf pan.

Bake at 350°F for about 60 minutes or until a toothpick inserted in the center comes out clean.

Remove from the oven and let cool on a wire rack for about 20 minutes.

Remove bread from the loaf pan and serve with soft butter.
