Ingredients
  

Main Ingredients
  • 3 large Overripe Bananas Mashed (approx 1.5 cups)
  • 1/2 cup Unsalted Butter 115g, melted
  • 3/4 cup Granulated Sugar 150g
  • 1 large Egg Room temperature
  • 1 tsp Vanilla Extract 5ml
  • 1.5 cups All-Purpose Flour 190g
  • 1 tsp Baking Soda 5g
  • 1/2 tsp Sea Salt 3g
  • 1/4 cup Brown Sugar 50g, packed
  • 1 tbsp Ground Cinnamon 8g
  • 1 cup Powdered Sugar 120g, sifted
  • 1.5 tbsp Whole Milk 22ml, adjust for thickness

Equipment

  • 1 9x5 Inch Loaf Pan Standard size for proper height.
  • 1 Wooden Skewer Used to create the caramelized swirl ribbon.

Method
 

Preparation
  1. Preheat oven to 350°F (175°C) and grease a 9x5 inch loaf pan, lining with parchment paper for easy removal.
  2. In a large bowl, mash bananas. Stir in melted butter, sugar, egg, and vanilla until smooth.
Assembly
  1. Gently fold in flour, baking soda, and salt until just combined—do not over-mix.
  2. Pour half the batter into the pan. Top with 3/4 of the cinnamon sugar. Add remaining batter, then remaining cinnamon sugar. Use a skewer to swirl once in a Z-pattern.
Bake and Finish
  1. Bake for 55-65 minutes until a deep golden-brown crust forms and a tester comes out clean.
  2. Once cooled, whisk powdered sugar and milk into a thick paste. Pour over the bread, allowing heavy droplets to form on the sides.

Notes

Use very overripe bananas for the best crumb moisture.
If the loaf browns too quickly, tent with foil at 45 minutes.
