Ingredients:

  • 3 large overripe bananas (approx. 340g), mashed
  • 1/2 cup unsalted butter (113g), melted and cooled
  • 3/4 cup granulated sugar (150g)
  • 1/4 cup light brown sugar (50g), packed
  • 2 tsp vanilla extract
  • 1 1/2 cups all-purpose flour (188g)
  • 1/2 tsp baking soda
  • 1/2 tsp fine sea salt
  • 1/2 cup semi-sweet chocolate chips (optional)
  • 1/4 cup unsalted butter (56g) for brown butter frosting
  • 1 1/2 cups powdered sugar (180g) for frosting
  • 1.5 tbsp milk (22g) for frosting
  • 1/2 tsp vanilla extract for frosting

Instructions:

  1. Preheat your oven to 180°C (350°F). Line an 8x8 inch square baking pan with parchment paper, leaving an overhang on the sides for easy removal.
  2. In a large mixing bowl, mash the overripe bananas until they reach a mostly liquid consistency with a few small lumps remaining.
  3. Whisk the 1/2 cup of melted butter into the mashed bananas. Add the granulated sugar, light brown sugar, and 2 teaspoons of vanilla extract. Stir until the mixture looks glossy and smooth.
  4. Gently fold in the all-purpose flour, baking soda, and sea salt using a silicone spatula. Stir just until combined to avoid over-activating gluten. Fold in chocolate chips if using.
  5. Pour the batter into the prepared pan and bake for 25 minutes, or until the edges are golden and the center is set.
  6. For the frosting: Brown 1/4 cup butter in a small saucepan over medium heat until it turns golden brown and smells nutty. Remove from heat and whisk in powdered sugar, milk, and vanilla until smooth. Spread over cooled brownies.
