These bakery style pumpkin sourdough muffins have a soft texture, big pumpkin spice flavor, and a buttery crumb topping. They are a super delicious way to start your day.
Making the batter: In a medium or large mixing bowl, stir together the 1 large egg, ⅓ cup sourdough discard, ½ cup pumpkin puree, ½ teaspoon vanilla extract, ¼ cup neutral cooking oil, ¼ cup granulated sugar, and ¼ cup light brown sugar.
In a small bowl, stir together the 1 cup all-purpose flour, 2 teaspoons pumpkin pie spice, ½ teaspoon baking soda, 1 teaspoon baking powder, and ½ teaspoon salt.
Add the dry ingredients to the pumpkin mixture. Stir to combine.
Overnight fermentation: Cover tightly with plastic wrap and chill in the refrigerator for 8-12 hours for added fermentation benefits. If baking same day, skip this step.
Before baking, preheat the oven to 400℉ and line 9 muffin wells with paper liners.
Crumb topping: In a medium bowl, stir together the ½ cup white whole wheat flour, ¼ cup light brown sugar, and ½ teaspoon ground cinnamon.
Add the ¼ cup salted butter and cut in with a fork or using your hands. The mixture should be crumbly.
Scoop 3-4 Tablespoons of batter into each muffin wrapper.
Distribute the crumb mixture evenly over all of the muffins. (About 1½-2 Tablespoons each)
Bake for 18-20 minutes. Let cool for a few minutes then transfer to a wire rack to cool completely.
Notes
Store muffins in an airtight container at room temperature for up to 4 days. Freeze for longer storage.
