Butter, or use cooking spray, on a standard 9” x 5” x 3” loaf pan. You can also use smaller loaf pans.
With an electric hand mixer, or a stand mixer, cream the butter and sugar well, until light and fluffly. Add the eggs, one at a time, and beat until well incorporated.
In a medium sized bowl, whisk together dry ingredients until well combined. Mix together with the butter/sugar/egg mixture; blend well.
Add the mashed bananas, sour cream, and vanilla; stir well.
Add the chocolate chips and stir just until combined, don’t over work the batter. The goal is to get them evenly distributed throughout the batter without over doing it.
Pour batter into prepared loaf pan, sprinkle entire top with raw or turbinado sugar. Bake for 60 minutes, or until a toothpick comes out clean.
Let cool on a rack in the pan for 10-15 minutes and then either turn out onto rack to finish cooling, or slice and serve.
