Step 1

Preheat the oven to 350 degrees Fahrenheit. Grease a 9x5x3-inch loaf pan with non-stick spray or butter.

Step 2

To a large mixing bowl, add softened butter and sugar. Beat with an electric mixer at medium speed until light and fluffy, about 5 minutes.

Step 3

Add the eggs, 1 by 1, beating until well-combined.

Step 4

Sift in the flour, baking soda, and salt. Beat just until combined, about 1-2 minutes.

Step 5

Add the mashed bananas, sour cream, and vanilla. Mix with a rubber spatula, then stir in the nuts.

Step 6

Pour the batter into the greased pan. Coat the chocolate chips lightly with flour, if using. Sprinkle floured chocolate chips over the batter.

Step 7

Bake for 1 hour or until a toothpick inserted into the center comes out clean. Let the bread cool in the pan for 10 minutes, and then transfer it onto a wire rack to cool. Slice, serve, and enjoy!
