Here’s the bold flavor-packed lineup for these Sourdough Coffee Cake Muffins. This list is clean, easy to find at your regular grocery store, and crafted for a crumbly streusel topping that makes these muffins sing!

1 cup active sourdough starter (fed or unfed—either works great in these sourdough starter muffins)
1/2 cup unsalted butter, melted and cooled
3/4 cup granulated sugar
2 large eggs
1 teaspoon vanilla extract
1 cup whole milk or oat milk for a dairy-free twist (grab this during your normal shopping trip!)
2 1/2 cups all-purpose flour
2 teaspoons baking powder
1/2 teaspoon baking soda
1/2 teaspoon salt
1 teaspoon ground cinnamon (this is the bold flavor that brings warmth and depth)

For that irresistible crumbly streusel topping:
1/2 cup brown sugar
1/3 cup all-purpose flour
1 teaspoon cinnamon
1/4 cup cold unsalted butter, cubed

Flavor booster alert: I love adding a pinch of nutmeg in the streusel topping for that cozy extra kick—trust me, it takes these Sourdough Coffee Cake Muffins to a whole new level!

No worries if you don’t have brown sugar; white sugar with a teaspoon of molasses is my go-to substitute that doesn’t sacrifice that signature richness. Plus, if you want to save time on prep, you can melt the butter in your microwave quickly instead of on the stove—little shortcuts like this make these muffins a go-to for weeknight baking sessions.

Pro tip: Keep these muffins fresh by storing them in an airtight container at room temperature for up to two days. For longer storage, pop them in the fridge wrapped tight or freeze for up to a month. When reheating, a quick zap in the microwave or a pop in the oven brings back that fresh-from-the-bakery vibe!

If you love sourdough baking adventures, these Sourdough Coffee Cake Muffins remind me a little of this tasty Sourdough Coffee Cake from Little Spoon Farm, which is a lovely take on sourdough baking with a similar cozy feel.

Alright, fellow flavor lovers, it’s time to roll up those sleeves and make magic with these Sourdough Coffee Cake Muffins! Ready? Let’s do this step by step.

1. Preheat your oven to 350°F (175°C) and line a 12-cup muffin tin with paper liners or grease well. The anticipation is real because the magic starts soon!

2. Whisk together wet ingredients: In a big mixing bowl, combine the melted butter, sugar, eggs, and vanilla extract until smooth. Then, stir in that glorious sourdough starter followed by the milk. Your kitchen should start smelling sweet and inviting right about now!

3. Mix dry ingredients: In another bowl, sift together flour, baking powder, baking soda, salt, and cinnamon. This combo sets the stage for those moist coffee cake muffins that everyone will crave.

4. Combine: Slowly fold the dry ingredients into the wet mix just until everything is well incorporated. Don’t overmix—this is where your moist texture is born! Small lumps are totally okay here.

5. Make the crumbly streusel topping: Toss the brown sugar, flour, cinnamon, and cold butter cubes into a bowl. Use a fork or pastry cutter to mix until the topping looks like coarse crumbs. This crumbly streusel topping is the crown jewel of these muffins and what makes them shine.

6. Fill your muffin cups: Spoon the batter equally into your prepared muffin tin. Then sprinkle generous amounts of that crumbly streusel topping over each. Press the crumbs lightly so they stick.

7. Bake: Slide your muffins into the oven. In my kitchen, these Sourdough Coffee Cake Muffins usually bake for about 22-25 minutes. Keep an eye out—the tops should be golden and a toothpick inserted in the center will come out with just a few moist crumbs.

8. Cool and enjoy: Let them cool in the pan for about 10 minutes, then transfer to a wire rack. The smell will pull all your hungry friends into the kitchen!

I love serving these beauties warm, right out of the oven, paired with a cup of rich coffee or creamy chai latte. The contrast of the warm, crumbly muffin with a smooth hot drink fuels my morning happy dance. If you want to wow guests at brunch, try topping the muffins with a dollop of whipped cream or a smear of homemade cream cheese frosting—trust me, it’s a crowd-pleaser!

For an unexpected twist, these muffins go insanely well alongside a scoop of cinnamon-spiced yogurt or a drizzle of honey for a delightful sweet and tangy combo. When serving at game nights or potlucks, I like to plate them on a bright tray with fresh berries and nuts for that extra pop of color and crunch.

Got leftovers? No problem! Crumble them up for a dessert parfait layered with vanilla yogurt and fresh fruit. Or toast a split muffin lightly and slather with butter for a quick afternoon boost.

If you’re into fusion flavor adventures, try folding fresh blueberries or chopped pecans into the batter next time. Added nuts with the crumbly streusel topping bring satisfying crunch and deeper flavor. I bet you’ll love these variations as much as I do.
