1/3 cup salted butter
3 bananas, ripe and peeled
1 cup granulated sugar
1 egg large, beaten
1 teaspoon vanilla extract
1-1/2 cups all-purpose flour
1 teaspoon baking soda
1/8 teaspoon salt
1/2 cup California walnuts, roughly chopped
Preheat oven to 350° F. Coat an 8×4-inch loaf pan with cooking spray.
Melt butter in small pan over medium heat. Cook and swirl the pan in circular motion for 5 minutes or until butter begins to foam and color changes to a golden brown. Once the butter has browned, remove from heat and allow to cool for 5 minutes.
In the bowl of an electric mixer or using a hand mixer, mash the ripe bananas until smooth. Add browned butter, sugar, beaten egg and vanilla extract and beat on low speed until just combined. Set aside.
In a medium bowl, sift together flour, baking soda and salt. Add the dry ingredients to the wet ingredients. Add chopped walnuts and mix thoroughly to combine.
Pour batter into prepared loaf pan. Bake for 50 minutes or until a toothpick comes out clean. If bread is browning too quickly, tent pan with aluminum foil.
Remove the bread from the oven and let cool in the loaf pan for 5 minutes. Run spatula along the sides of the pan before transferring the bread to a wire rack to cool for another 20 minutes.
When bread has cooled almost completely, slice and serve.
