Sourdough Bourbon Banana Bread

This sourdough banana bread recipe is the only one you'll ever need. Mashed bananas are soaked in bourbon. Tangy sourdough starter discard gets used up. And then a generous top layer of cinnamon sugar gets a wee bit caramelized for a delicious bite.

Equipment

  • loaf pan

Ingredients
  

  • 3-4* ripe bananas
  • 1 oz bourbon
  • 100 g (1/2 cup) unsalted butter softened + extra for greasing
  • 100 g (1/2 cup) sugar
  • 100 g (1/2 cup) brown sugar
  • 1 egg
  • 1 tsp vanilla extract
  • 250 g (1 cup) sourdough starter discard stirred

Dry Ingredients

  • 180 g (1 1/2 cups) all-purpose flour + extra for dusting
  • 1 tsp baking powder
  • 1/2 tsp baking soda
  • 1/4 tsp salt

Cinnamon Sugar

  • 1/4 cup sugar
  • 1 tbsp cinnamon

Instructions
 

  • Roughly an hour before baking, mash up the bananas, stir in the bourbon, and cover them up. Let them soak, steep, macerate.
  • Preheat the oven to 350ºF/175ºC.
  • Prepare a loaf pan by greasing it with butter and dusting it with flour
  • In a medium bowl, mix the dry ingredients together.
  • In a large mixing bowl, cream the butter with both of the sugars.
  • Add the egg to the creamed butter and sugar and beat it in until it's fully incorporated, then mix in the vanilla, sourdough discard, and bourbon bananas.
  • Fold in the dry ingredients until combined.
  • Transfer the batter to the prepared loaf pan, leaving an inch of space to prevent overflow. If there's extra batter, fill up a few muffin tins (those take 25-30 minutes to bake).
  • In a small jar, shake up the cinnamon and sugar to combine it, then sprinkle a generous layer (as much as you'd like) over the loaf prior to baking.
  • Bake for one hour, checking for doneness with a toothpick.
  • Once out of the oven, allow the loaf to sit in the pan for 10-15 minutes before turning it out on a cooling rack to cool completely.

Notes

  • For extra batter (to make muffins), use 4 bananas.
  • Consider adding chocolate chips or walnuts to the batter.
  • If you don't have bourbon on hand, bananas also pair well with rum and brandy.
  • Maple syrup may be used in place of the brown sugar, but use 66g instead of 100g
