Ingredients:

  • 3 large overripe bananas, mashed (approx. 340g)
  • 1/2 cup melted unsalted butter (115g)
  • 3/4 cup packed light brown sugar (150g)
  • 1 large egg, room temperature (50g)
  • 1 tsp pure vanilla extract (5ml)
  • 1/4 cup sour cream (60g)
  • 1 1/2 cups all-purpose flour (190g)
  • 1 tsp baking soda (5g)
  • 1/2 tsp salt (3g)
  • 1/2 tsp ground cinnamon (1g)

Instructions:

  1. Preheat oven to 350°F (175°C). Grease a 9x5 inch loaf pan and line with parchment paper.
  2. In a large mixing bowl, mash the overripe bananas until no large lumps remain.
  3. Whisk in the melted butter, brown sugar, egg, vanilla extract, and sour cream until the mixture is a smooth, cohesive emulsion.
  4. Sift the all-purpose flour, baking soda, salt, and ground cinnamon directly into the wet base.
  5. Using a rubber spatula, gently fold the dry ingredients into the wet base until no more streaks of flour are visible. Do not overmix.
  6. Pour the batter into the prepared loaf pan and bake for 65 minutes, or until the top is deep mahogany and a toothpick inserted in the center comes out clean.
