Ingredients:

  • 1/2 cup Unsalted Butter (1 stick), cubed
  • 1/2 cup Granulated Sugar
  • 1/2 cup Light Brown Sugar, packed
  • 2 Large Eggs, room temperature
  • 1 teaspoon Pure Vanilla Extract
  • 1 1/2 cups Very Ripe Bananas, mashed (3-4 large)
  • 1/4 cup Buttermilk or Greek Yogurt
  • 1 3/4 cups All-Purpose Flour
  • 1 teaspoon Baking Soda (Bicarbonate of Soda)
  • 1 teaspoon Ground Cinnamon
  • 1/2 teaspoon Fine Sea Salt
  • 1/2 cup Chopped Walnuts or Pecans (Optional)

Instructions:

  1. Preheat your oven to 350°F (175°C). Grease and flour your loaf pan, or line it completely with parchment paper, leaving an overhang 'sling' for easy removal.
  2. Brown the Butter: Place the cubed butter in a saucepan over medium heat. Cook, stirring occasionally, until the butter melts, foams, and develops small brown specs at the bottom and a nutty aroma (5-7 minutes).
  3. Cool: Immediately pour the brown butter (including the browned bits) into a large mixing bowl. Allow it to cool for 5 minutes—it should still be warm, but not hot enough to scramble the eggs.
  4. Combine Fats & Sugars: Whisk the granulated sugar and brown sugar into the slightly cooled brown butter until thoroughly combined.
  5. Introduce Eggs: Whisk in the eggs one at a time, ensuring each is fully incorporated before adding the next. Stir in the vanilla extract.
  6. Mash the Bananas: Mash the very ripe bananas, leaving them slightly chunky. Fold the mashed bananas and buttermilk (or yogurt) into the brown butter mixture using a rubber spatula.
  7. Sift Dry Ingredients: In a separate medium bowl, whisk together the flour, baking soda, cinnamon, and salt. Sifting prevents lumps and helps aeration.
  8. Fold Wet into Dry: Add the dry mixture to the wet mixture. Use the rubber spatula to gently fold them together until just combined. Stop mixing the very second you no longer see streaks of dry flour. If using nuts, gently fold them in now.
  9. Bake: Pour the batter into the prepared loaf pan, smoothing the top with the spatula. Bake for 55–65 minutes.
  10. Test for Doneness: The bread is done when a long, thin skewer inserted into the center comes out clean or with just a few moist crumbs attached.
  11. Rest and Cool: Remove the bread from the oven and allow it to cool in the pan for 10–15 minutes. Use the parchment sling to lift the bread onto a wire rack. Let it cool fully (30 minutes to an hour) before slicing.
