Equipment

- Whisk
- wooden spoon
- Electric hand mixer (optional)
Ingredients
For the bread:
- Butter for greasing the pan
- 137 g 1 ⅛ cups all purpose flour
- 12 g 2 teaspoons baking powder
- 1.5 g ¼ teaspoon baking soda
- 2 g 1 teaspoon ground cinnamon
- 225 g mashed bananas about 1 ½ cups
- 1 egg
- 156 g ¾ cup brown sugar
- 100 g ⅓ cup sourdough discard
- 22 g 1 ½ tablespoons butter, melted
For the frosting
- ¼ cup butter
- 1/2 cup light brown sugar
- 3 tablespoons heavy cream
- 1 cup powdered sugar sifted
Instructions
For the bread:
- Preheat the oven to 350° and grease the loaf pan with butter and set aside.
- In a mixing bowl, whisk together the flour, baking powder, baking soda, and cinnamon until well combined, set aside.
- In another mixing bowl, add the mashed bananas, egg, brown sugar, and sourdough discard, whisk together until thoroughly combined and blended together.
- Make a well in the flour mixture, and pour the mixed wet ingredients into the center. Gently stir until just combined.
- Pour into the greased loaf pan, and bake for 50-60 minutes. It’s finished when the edges have pulled away from the pan, the top is golden brown, and a toothpick inserted into the center comes out clean.
- Allow to cool in the pan on a rack for 15 minutes, then carefully remove the bread from the pan and let it cool completely on the rack.
- Once the bread is completely cooled, spread the frosting on top. Allow it to set before serving.
For the frosting:
- Melt the butter and sugar together over medium low heat, whisking them together until they are incorporated.
- Bring the mixture to a boil, and boil for 2 minutes. Stir constantly.
- Add the heavy cream, and stir to combine. Allow the mixture to come to a boil again, and then remove it from the heat. Stir in the sifted powdered sugar until combined. If you prefer, you can use a hand mixer to blend the sugar in so it’s nice and smooth.
- Using a rubber spatula, gently spread the frosting over the cooled banana bread.
Notes
- Although this recipe calls for unfed sourdough starter (discard), you can also use active, bubbly sourdough starter.
- You can substitute white sugar for the brown sugar if desired.
- Milk or half and half work just fine in the icing if you don’t have heavy cream.
- Ovens vary, start checking for doneness at 45 minutes.
- The bread is finished when it is golden brown, the edges are pulling away from the side, and a toothpick inserted in the center comes out clean.
