These sourdough pumpkin coffee cake muffins are made with sourdough discard, warm spices, and pumpkin. This easy same-day sourdough recipe brings together cozy fall flavors in a soft, spiced muffin that's perfect for breakfast, dessert, or an afternoon snack.
Stir the brown sugar, flour, and cinnamon together in a bowl. Add the melted butter and mix to combine. Set aside.
Sourdough Pumpkin Coffee Cake Batter
Preheat your oven to 350℉ (175℃). Place muffin liners in muffin tins and set aside.
In a large mixing bowl cream together sugar and softened butter. Add vanilla extract, eggs, milk, sourdough discard (or active starter), and pumpkin puree. Mix to combine.
Add the baking powder and pumpkin pie spice. Mix to combine well, then add the flour, and mix.
Scoop a spoonful of batter into the bottom of the muffin liners. Use about half of the batter to fill the bottoms of the muffin liners. Set the other half aside. Use half of the cinnamon sugar mixture and sprinkle some into each muffin liner. Use the other half of the batter to top and then crumble the remaining cinnamon sugar on top of each muffin.
Bake for 25-30 minutes at 350℉ (175℃) until the tops are golden brown and a toothpick inserted into the middle comes out clean.
Cinnamon Vanilla Glaze
While the sourdough pumpkin coffee cake muffins are cooling, make the glaze by mixing up powdered sugar, ground cinnamon, vanilla extract, and milk. Start by adding 1 Tablespoon milk to the mixture and gradually add more to get your desired consistency for the drizzle. Drizzle over muffins and enjoy!
