Ingredients
Scale
- 1/2 cup (113g) unsalted butter, melted
- 1 cup (200g) dark brown sugar, packed
- 3 ripe bananas (about 350g), mashed
- 2 large eggs, room temperature
- 1/2 cup (120g) sourdough starter discard
- 1 teaspoon vanilla extract
- 2 cups (250g) all-purpose flour
- 1 teaspoon baking soda
- 2 teaspoons baking powder
- 1 teaspoon salt
- For the crumble topping:
- 1/2 cup (100g) brown sugar
- 1/2 cup (45g) rolled oats
- 2 tablespoons (16g) all-purpose flour
- 4 tablespoons (56g) unsalted butter, softened
- 1 teaspoon ground cinnamon
Instructions
- Preheat the oven to 350°F (175°C) and line a 12-cup muffin tin with paper liners or lightly grease it.
- In a large mixing bowl or stand mixer, beat the melted butter and brown sugar together for about 5 minutes until smooth and slightly fluffy.
- Add the eggs, mashed bananas, sourdough starter discard, and vanilla extract. Mix until fully combined.
- In a separate bowl, whisk together the flour, baking soda, baking powder, and salt.
- Gradually add the dry ingredients to the wet mixture in three additions, mixing just until incorporated. Do not overmix.
- Divide the batter evenly among the prepared muffin cups, filling each about 3/4 full.
- In a small bowl, combine brown sugar, oats, flour, softened butter, and cinnamon to form a crumbly topping. Sprinkle evenly over each muffin.
- Bake for 20–25 minutes, or until a toothpick inserted into the center comes out clean.
- Allow the muffins to cool in the pan for 5 minutes before transferring to a wire rack. Serve warm or at room temperature.
Notes
- For a stronger tangy flavor, use sourdough discard that has not been recently fed.
- For long fermentation, increase sourdough starter to 1 cup (240g) and mix with flour, butter, and sugar. Cover and ferment 6–24 hours before adding remaining ingredients.
- Use very ripe bananas with brown spots for the sweetest flavor and moist texture.
- Do not overmix the batter to keep the muffins light and fluffy.
- Store in an airtight container at room temperature for up to 4 days or freeze for up to 3 months.
