Ingredients:

  • 2 cups (250g) all-purpose flour
  • 1 tsp (5g) baking soda
  • ½ tsp (3g) salt
  • 1 cup (200g) granulated sugar
  • ½ cup (120ml) neutral oil
  • 1 cup (240ml) full-fat buttermilk
  • 2 large (100g) eggs, room temperature
  • 2 tsp (10ml) vanilla extract
  • 3 medium (350g) overripe bananas, mashed
  • 2 cups (240g) powdered sugar, sifted
  • ¼ cup (60ml) buttermilk
  • 1 tsp (5ml) vanilla bean paste or extract
  • Pinch (1g) salt

Instructions:

  1. Preheat the oven to 350°F (175°C) and grease a 9x13 inch baking pan.
  2. In a medium bowl, whisk together the flour, baking soda, and salt until combined.
  3. In a large bowl, whisk together the granulated sugar, oil, buttermilk, eggs, and vanilla until the mixture is smooth and pale.
  4. Stir in the mashed bananas until just incorporated, taking care not to overmix.
  5. Gently fold the dry ingredients into the wet ingredients using a spatula until no streaks of flour remain.
  6. Pour the batter into the prepared pan and bake for 50–60 minutes, or until the edges are deep mahogany-gold and a toothpick inserted into the center comes out clean.
  7. Transfer the cake to a wire rack and allow it to cool completely.
  8. Whisk together the powdered sugar, buttermilk, vanilla, and salt until the glaze is thick but pourable.
  9. Drizzle the glaze over the cooled cake in a zigzag pattern.
