Moist, fluffy, and full of cozy fall flavors, these sourdough pumpkin muffins combine pumpkin puree with a hint of tang from sourdough. Perfect for breakfast, snacks, or dessert, and easy to customize with nuts or chocolate chips.
Prep the Pan: Grease or line a 12-cup muffin tin with paper liners. Preheat oven to 350°F (175°C).
Mix Wet Ingredients: In a large mixing bowl, whisk together sourdough starter, pumpkin puree, oil, eggs, brown sugar, and vanilla until smooth.
Combine Dry Ingredients: In a separate bowl, whisk flour, baking soda, baking powder, cinnamon, nutmeg, ginger, and salt.
Make the Batter: Gently fold dry mixture into wet mixture until just combined. Do not overmix. Stir in any optional mix-ins.
Bake the Muffins: Scoop batter evenly into the muffin tin, filling each about ⅔ full. Bake for 20–25 minutes, or until a toothpick inserted in the center comes out clean.
Cool & Serve: Cool muffins in the pan for 5 minutes, then transfer to a wire rack. Enjoy warm or at room temperature.
