Sourdough banana muffins are a gourmet twist on a classic banana muffin. Let the batter rest before baking for tall, bakery-style tops. This recipe includes a how-to video.
Why You’ll Love This Recipe
- Bakery-style results: Tall, sugar-crisped muffin tops make these soudough banana muffins look like they came from a bakery display.
- Deep flavor: Overripe bananas, pure vanilla, and tangy sourdough discard combine for an intense, layered banana flavor.
- Easy technique: No mixer required — gently fold the batter by hand to avoid overworking it for a tender crumb.
- Make-ahead friendly: The batter benefits from a short rest before baking, so you can prepare ahead and bake when ready.
These soft, tender sourdough banana muffins build on simple ingredients to deliver a fluffy, flavorful result. The discard adds a subtle tang and extra depth that elevates an otherwise familiar muffin.
A quick note from testing: it took several tries to balance rise, texture, and flavor. The resting step and a brief high-heat start are small adjustments that make a big difference for tall, moist muffins.
What You Need
- Bananas: Use very ripe, spotty bananas for the best moisture and sweetness (about 3–4 bananas to yield 1 1/4 cups mashed).
- Sourdough discard: Adds flavor and a touch of tang. You can substitute active starter if measured carefully.
- Egg: One large egg, preferably at room temperature.
- Vanilla extract: Enhances the banana flavor and rounds the taste.
- Coarse sugar (optional): Sprinkle on top before baking for sparkle and a slight crunch — turbinado or baking sugar works well.
SAM’S TIP: If you want mix-ins, stir in up to 1 cup of nuts, dried fruit, or chocolate chips. Toast nuts first for better flavor.

How to Make Sourdough Banana Muffins
Make & rest the batter
Whisk the wet ingredients together, and in a separate bowl combine the dry ingredients. Fold the dry into the wet until just combined — do not over-mix. Letting the batter rest for about 30 minutes gently hydrates the flour and encourages taller, lighter muffin tops.
Portion into liners
Use an ice cream scoop or large spoon to divide the batter evenly into a lined 12-cup muffin tin. If desired, sprinkle coarse sugar on top for texture and shine. You can also top with streusel or a glaze if preferred.
Bake
Bake at a high temperature for a short time, then lower the oven temperature to finish baking. This two-step method helps the muffins rise tall and then bake through without drying out. After baking, let the muffins rest in the pan briefly, then transfer to a rack to cool completely.
SAM’S TIP: If you prefer banana bread instead of muffins, the same flavor profile works well in loaf form using a sourdough banana bread recipe.
Frequently Asked Questions

Sourdough Banana Muffins
Equipment
- 12-count muffin tin
- Mixing bowls
Ingredients
- 1 1/4 cups (312 g) well-mashed ripe bananas (about 3–4)
- 1/2 cup (110 g) sourdough discard
- 1/2 cup (113 g) unsalted butter, melted
- 1/2 cup (100 g) granulated sugar
- 1/3 cup (67 g) light brown sugar, firmly packed
- 1 large egg, room temperature preferred
- 2 teaspoons vanilla extract
- 1 1/2 cups (190 g) all-purpose flour
- 1 teaspoon baking soda
- 1/2 teaspoon baking powder
- 1/2 teaspoon table salt
- Coarse sugar for sprinkling tops (optional)
Instructions
- Note: Letting the batter rest for 30 minutes yields taller muffin tops. If you skip resting, preheat oven to 425°F (220°C) now.
- In a large bowl, whisk together mashed bananas, sourdough discard, melted butter, granulated sugar, brown sugar, egg, and vanilla.
- In a separate medium bowl, whisk together flour, baking soda, baking powder, and salt.
- Add the dry ingredients to the wet and gently fold with a spatula until just combined. Do not over-mix.
- Cover the batter and let rest 30 minutes. While it rests, preheat the oven to 425°F (220°C) and line a 12-cup muffin tin with paper liners.
- After resting, divide the batter evenly into the muffin tin and sprinkle tops with coarse sugar if using.
- Bake for 8 minutes at 425°F (220°C). Do not open the oven; reduce the temperature to 350°F (175°C) and bake another 7–8 minutes, until a toothpick inserted in the center comes out clean or with a few moist crumbs.
- Cool in the tin for 5–10 minutes, then transfer muffins to a cooling rack.
Notes
Sugar
Coarse or turbinado sugar gives a pleasant crunch on top, but regular granulated sugar works fine.
Storing
Store muffins in an airtight container at room temperature for up to 3 days. For longer storage, wrap tightly and freeze up to 3 months.
