There’s nothing better than the smell of warm coffee cake baking in the oven, especially when it comes in the form of soft, bakery-style muffins. The first time I made Sourdough Discard Coffee Cake Muffins, I wanted a simple way to use leftover sourdough discard while creating something special for breakfast.

The tender muffins, buttery cinnamon streusel, and sweet vanilla glaze turned out even better than I imagined. They disappeared before they had a chance to cool completely. Now these Sourdough Discard Coffee Cake Muffins are one of my favorite recipes for weekend breakfasts, brunches, and afternoon coffee breaks because they’re easy to make and always a hit.

Ingredients for Sourdough Discard Coffee Cake Muffins

Ingredient Notes

• Sourdough Discard: Unfed sourdough discard adds subtle tangy flavor while keeping the muffins moist and tender.

• All-Purpose Flour: Provides the structure for soft, fluffy muffins without making them heavy.

• Baking Powder: Gives the muffins a beautiful rise and light texture.

• Brown Sugar: Adds moisture and rich caramel notes to both the muffin batter and the streusel topping.

• Granulated Sugar: Sweetens the batter while helping the muffins develop a lightly golden top.

• Ground Cinnamon: The key ingredient for the classic coffee cake flavor found in the streusel.

• Unsalted Butter: Melted butter enriches the batter, while cold butter creates a crumbly, buttery streusel topping.

• Eggs: Help bind the ingredients together and contribute to a soft, tender crumb.

• Sour Cream: Keeps the muffins exceptionally moist and adds richness. Plain Greek yogurt also works well.

• Vanilla Extract: Enhances the warm cinnamon flavor and gives the muffins a classic bakery-style taste.

• Powdered Sugar: Combined with a little milk and vanilla, it creates the sweet glaze drizzled over the cooled muffins.

With these simple ingredients, you’ll create Sourdough Discard Coffee Cake Muffins that are soft, moist, topped with buttery cinnamon streusel, and finished with a delicate vanilla glaze, perfect for breakfast, brunch, or an afternoon treat with coffee.

How to Make Sourdough Discard Coffee Cake Muffins

Making Sourdough Discard Coffee Cake Muffins is simple and rewarding. The batter comes together quickly, while the buttery cinnamon streusel and sweet vanilla glaze give these muffins their bakery-style finish.

1. Prepare the Oven and Muffin Pan

• Preheat your oven to 375°F (190°C).

• Line a 12-cup muffin pan with paper liners or lightly grease each cup with nonstick spray.

2. Make the Streusel Topping

In a small bowl, combine:

• Brown sugar
• All-purpose flour
• Ground cinnamon

Cut in the cold butter with a fork or pastry cutter until the mixture resembles coarse crumbs.

Place the streusel in the refrigerator while preparing the muffin batter.

3. Mix the Dry Ingredients

In a large bowl, whisk together:

• All-purpose flour
• Baking powder
• Salt
• Ground cinnamon

Set aside.

4. Mix the Wet Ingredients

In another bowl, whisk together:

• Sourdough discard
• Eggs
• Brown sugar
• Granulated sugar
• Sour cream
• Melted butter
• Vanilla extract

Whisk until smooth and fully combined.

5. Make the Batter

• Pour the wet ingredients into the bowl of dry ingredients.

• Gently fold everything together until just combined. A few small lumps are perfectly fine. Avoid overmixing to keep the muffins soft and tender.

6. Fill and Top

• Divide the batter evenly among the prepared muffin cups, filling each about three-quarters full.

• Generously sprinkle the chilled cinnamon streusel over each muffin, gently pressing it into the batter so it stays in place while baking.

7. Bake

• Bake for 20 to 24 minutes, or until the muffins are golden brown and a toothpick inserted into the center comes out clean.

• Let the muffins cool in the pan for 5 minutes, then transfer them to a wire rack.

8. Add the Vanilla Glaze

• Once the muffins have cooled slightly, whisk together powdered sugar, a little milk, and vanilla extract until smooth.

• Drizzle the glaze over each muffin before serving.

Variations and What to Serve With

One of the best things about Sourdough Discard Coffee Cake Muffins is how easy they are to customize for every season.

• Add chopped pecans or walnuts to the streusel for extra crunch, or fold blueberries, diced apples, or mini chocolate chips into the batter.

• You can also replace the vanilla glaze with a maple glaze or add a pinch of nutmeg to the streusel for even more warm spice flavor.
