Sourdough Coffee Cake Muffins Recipe
Introduction
These Sourdough Coffee Cake Muffins are a delightful way to use your sourdough discard or starter. They combine a tender crumb with a cinnamon sugar filling and a sweet vanilla glaze, perfect for breakfast or an afternoon treat.

Ingredients
- ½ cup butter (1 stick, softened)
- 1½ cup white sugar
- 2 teaspoons vanilla extract
- 2 eggs
- 1 cup milk
- ¾ cup sourdough discard or active starter
- 4 teaspoons baking powder
- 3 cups all purpose flour
- 1½ cup brown sugar
- 5 tablespoons flour
- 4 teaspoons ground cinnamon
- 6 tablespoons butter (melted)
- ⅔ cup powdered sugar
- 1 teaspoon vanilla extract (for glaze)
- ½-1 tablespoon milk (for glaze)
Instructions
- Step 1: Prepare the cinnamon sugar filling and topping by mixing the brown sugar, flour, and ground cinnamon in a bowl. Stir in the melted butter until well combined. Set aside.
- Step 2: Preheat your oven to 350℉ (175℃). Line a muffin tin with large bakery-style muffin liners and set aside. Large liners are important for this recipe as the muffins rise significantly.
- Step 3: In a large mixing bowl, cream together the softened butter and white sugar until light and fluffy. Add the vanilla extract, eggs, milk, and sourdough discard or active starter. Mix until combined.
- Step 4: Add the baking powder and flour to the wet ingredients. Mix gently until just combined; avoid over-mixing to keep the muffins fluffier.
- Step 5: Spoon batter into each muffin liner, filling them halfway. Add a spoonful of the cinnamon sugar mixture on top of the batter, then add another spoonful of batter over that. Finally, crumble and press the remaining cinnamon sugar mixture onto the tops, filling the muffin cups to the top.
- Step 6: Bake the muffins for 25 to 30 minutes at 350℉ (175℃), until the tops are golden brown and a toothpick inserted into the center comes out clean. Avoid overbaking to prevent dryness.
- Step 7: While the muffins cool, make the vanilla glaze by combining powdered sugar, vanilla extract, and ½ tablespoon milk. Gradually add more milk as needed to achieve a drizzle consistency.
- Step 8: Drizzle the glaze over the cooled muffins and serve.
Tips & Variations
- Use large muffin liners as they help contain the rising batter and maintain the muffin shape during baking.
- For a richer flavor, substitute half the milk with buttermilk.
- Add chopped nuts or raisins to the cinnamon sugar filling for added texture.
- If you don’t have sourdough discard, you can substitute with an equal amount of yogurt or sour cream to add moisture and tang.
- Adjust the glaze thickness by adding milk gradually for a thicker or thinner drizzle as desired.
Storage
Store the muffins in an airtight container at room temperature for up to 2 days. For longer storage, keep them in the refrigerator for up to 5 days or freeze for up to 2 months. Reheat refrigerated or frozen muffins in the microwave for 20–30 seconds to restore softness before serving.

FAQs
Can I use active sourdough starter instead of discard?
Yes, you can use your active starter in place of the discard. Just ensure the starter is fed recently and bubbly for the best texture and rise.
What if I don’t have large muffin liners?
Large liners help the muffins hold their tall shape as they rise. If you only have standard liners, expect smaller muffins and consider reducing the filling to prevent overflow.

Vanilla Glaze
- ⅔ cup powdered sugar
- 1 teaspoon vanilla extract
- ½–1 tablespoon milk
Instructions
- Prepare Cinnamon Sugar Filling + Topping: Stir together brown sugar, flour, and ground cinnamon in a bowl. Add melted butter and mix well to combine. Set this mixture aside while you prepare the batter.
- Preheat Oven and Prepare Muffin Tin: Preheat your oven to 350℉ (175℃). Line a muffin tin with bakery-style large muffin liners, which are important to hold the muffins as they expand during baking.
- Make the Muffin Batter: In a large mixing bowl, cream the softened butter with white sugar until light and fluffy. Add vanilla extract, eggs, milk, and sourdough discard or active starter, mixing to combine thoroughly.
- Add Dry Ingredients: Sprinkle baking powder and all-purpose flour into the wet mixture. Stir gently until just combined; be careful not to overmix to keep the muffins tender and fluffy.
- Assemble Muffins: Spoon about half the batter into each muffin liner, filling cups halfway. Add a spoonful of the cinnamon sugar filling on top. Cover with the remaining batter, filling the liners nearly to the top. Crumble and press the remaining cinnamon sugar topping over each muffin, ensuring they fill the cups completely for a nice rise.
- Bake: Bake in the preheated oven for 25-30 minutes or until the muffins are golden brown, and a toothpick inserted in the center comes out clean. Avoid overbaking to prevent dryness.
- Prepare Vanilla Glaze: While muffins cool, whisk powdered sugar with vanilla extract and start adding milk gradually (starting with ½ tablespoon) until the glaze reaches a drizzle-able consistency.
- Glaze and Serve: Drizzle the vanilla glaze over cooled muffins and serve. Enjoy your perfectly moist sourdough coffee cake muffins!
