Equipment

9x5" loaf pan
Large mixing bowl
electric handheld mixer or stand mixer
Wire cooling rack

Ingredients

For the Batter:

3/4 cup brown sugar
1/4 cup granulated sugar
1/3 cup neutral-flavored oil or melted butter
1/3 cup sourdough starter discard or fed
2 eggs
1/4 cup sour cream or plain greek yogurt
1 cup mashed over-ripe bananas about 2 large bananas
2 teaspoons vanilla extract
1 and 3/4 cups all-purpose flour
1 teaspoon baking soda
1 teaspoon baking powder
1/2 teaspoon ground cinnamon
1/4 teaspoon ground nutmeg
3/4 teaspoon salt
1/3 cup chopped walnuts optional

For Crunchy Struesel Topping:

3 tablespoons all-purpose flour
1/4 cup brown sugar
1/4 teaspoon cinnamon
2 tablespoons cold unsalted butter
1/4 cup chopped walnuts or old-fashioned rolled oats

Instructions

Preheat oven to 325 degrees F. Grease a 9x5" loaf pan with butter or baking spray.
In a large bowl, beat the sugars and oil, then add the starter, eggs, sour cream, mashed bananas, and vanilla extract and mix until combined. Scrape down sides as needed.
Sprinkle the flour, baking soda, baking powder, cinnamon, nutmeg, and salt over the wet ingredients and mix until just combined. Be careful not to overmix. Fold in the chopped nuts or add-ins.
Pour the batter into the prepared loaf pan and bake for 1 hour and 10 minutes, tenting about halfway through with aluminum foil to prevent over-browning.
Let baked banana bread cool in the pan for 20 minutes then remove it to a wire rack to finish cooling.

For optional Streusel Topping:

In a small bowl, combine the flour, sugar, and cinnamon. Cut in the cold butter and fold in the chopped nuts. Sprinkle the mixture over the top of the batter right before baking.

Notes

Tip: For best results, bring all the ingredients to room temperature before mixing up the batter. [starter, eggs, sour cream, (and bananas if using frozen)].

Sourdough Banana Bread Muffins: You can use this recipe to make regular or mini banana muffins. For regular-size muffins, bake at 350 degrees F for 18-20 minutes. For mini muffins, 10-12 minutes. Bake times can vary, remove muffins when golden brown and a toothpick inserted into the center comes out clean or with just a few crumbs.
