Sourdough Banana Muffins

1 cup unfed sourdough starter
1 cup banana
3/4 cup granulated sugar
1/4 cup vegetable oil
1 medium egg
1 cup all-purpose flour
1 teaspoon baking soda
1 teaspoon ground cinnamon
1/2 teaspoon salt


Directions:

1. Preheat the oven to 350°F. Line muffin tins with paper muffin cups and set aside.
2. In a large mixing bowl, beat together the sourdough starter, mashed bananas, sugar, vegetable oil, and egg until the mixture is smooth.
3. In a separate bowl whisk together the all-purpose flour, baking soda, cinnamon, and salt. Add the dry ingredients to the wet mixture and fold together with a spatula until the dry ingredients are just incorporated.
4. Fill the prepared muffin cups about 3/4 full of batter.
5. Bake the muffins for 18 - 20 minutes, until a toothpick inserted in the center of the muffin comes out clean (or with a few wet crumbs).
6. Transfer to a wire rack to cool.
