Best Sourdough Cinnamon Muffins with Crumb Topping
If your kitchen could smell like a bakery every single morning, these Sourdough Cinnamon Muffins with Crumb Topping would be the reason why. Tender, warmly spiced, and crowned with a buttery brown sugar crumble, they strike that perfect balance between a muffin and a coffee cake in one irresistible handheld bite. Whether you bake them for a lazy Sunday brunch or prep a batch to fuel busy weekday mornings, this sourdough cinnamon muffins recipe is the kind you will return to again and again.
What sets these apart from your average bakery muffin is the sourdough starter. That slight tang from the starter adds a subtle depth of flavor that plain muffins simply cannot replicate. Pair that with the warm fragrance of cinnamon, pockets of melty cinnamon chips, and a gloriously crunchy crumb topping, and you have something truly special sitting in your muffin tin.
What Makes This Recipe Special
- Sourdough depth of flavor: Using sourdough discard gives these cinnamon sugar muffins a gentle tang that elevates every bite beyond a standard quick bread.
- Bakery-style crumb topping: That crunchy, buttery streusel on top is not an afterthought. It adds texture and a rich brown sugar sweetness that makes these muffins feel indulgent without being over the top.
- Cinnamon chip magic: Folding cinnamon chips into the batter means you get little bursts of warm spice in every bite, making these genuinely reminiscent of the best cinnamon chip muffins from your favorite coffee shop.
- Simple pantry ingredients: No specialty store run required. Most of what you need is already in your kitchen.
Essential Ingredients
- Sourdough discard (1 cup): Unfed discard works perfectly here. It adds moisture and that signature tang without needing to be active.
- All-purpose flour (2 cups): The backbone of the muffin. Spoon and level for accuracy.
- Brown sugar (3/4 cup, packed): These are true brown sugar muffins at heart. Dark or light brown sugar both work, but dark gives a deeper molasses note.
- Cinnamon (2 teaspoons): Use a fresh, fragrant ground cinnamon for the best results.
- Cinnamon chips (3/4 cup): The secret weapon. Find them in the baking aisle or online.
- Eggs (2 large): Room temperature eggs incorporate more evenly into the batter.
- Unsalted butter (1/2 cup, melted): Adds richness and keeps the crumb soft.
- Whole milk (1/2 cup): Lends moisture and a tender texture.
- Baking powder (2 teaspoons) and baking soda (1/2 teaspoon): The lift duo that gives these muffins their domed tops.
- Vanilla extract (1 teaspoon): Rounds out the warm spice profile beautifully.
- Salt (1/2 teaspoon): Never skip it. Salt balances the sweetness.
- For the crumb topping: flour (1/2 cup), brown sugar (1/3 cup), cinnamon (1 teaspoon), cold butter (4 tablespoons, cubed): Combined into a coarse, sandy streusel that bakes up perfectly crunchy.
Using quality tools and fresh ingredients makes all the difference between good muffins and truly great ones. A reliable muffin tin, a sturdy mixing bowl, and a pastry cutter for the crumb topping are small investments that pay off every time you bake.

Sourdough Cinnamon Muffins with Crumb Topping
Equipment
- 12-cup standard muffin tin
- Large mixing bowl
- Medium mixing bowl
- Small bowl for crumb topping
- Pastry cutter or fork
- Wire cooling rack
- Muffin liners or nonstick spray
Ingredients
Muffin Batter
- 2 cups all-purpose flour spooned and leveled
- 2 teaspoons baking powder
- 1/2 teaspoon baking soda
- 2 teaspoons ground cinnamon fresh and fragrant
- 1/2 teaspoon salt
- 3/4 cup brown sugar packed, light or dark
- 1 cup sourdough discard unfed, room temperature
- 1/2 cup unsalted butter melted and slightly cooled
- 2 large eggs room temperature
- 1/2 cup whole milk room temperature
- 1 teaspoon vanilla extract
- 3/4 cup cinnamon chips found in the baking aisle
Crumb Topping
- 1/2 cup all-purpose flour
- 1/3 cup brown sugar packed
- 1 teaspoon ground cinnamon
- 4 tablespoons unsalted butter cold, cut into small cubes
Instructions
- Preheat your oven to 375 degrees F (190 degrees C). Line a standard 12-cup muffin tin with paper liners or grease thoroughly with nonstick spray.
- Make the crumb topping: In a small bowl, combine the flour, brown sugar, and cinnamon. Add the cold cubed butter and use a pastry cutter or your fingertips to work it in until the mixture resembles coarse, pea-sized crumbles. Place the bowl in the refrigerator while you prepare the muffin batter.
- In a large mixing bowl, whisk together the flour, baking powder, baking soda, cinnamon, and salt until evenly combined and no lumps remain.
- In a separate medium bowl, whisk together the sourdough discard, melted butter, eggs, brown sugar, milk, and vanilla extract until smooth and fully blended.
- Pour the wet ingredients into the dry ingredients and fold gently with a rubber spatula until just combined. A few small lumps in the batter are completely fine. Stop mixing as soon as no dry streaks of flour are visible to avoid overworking the gluten.
- Add the cinnamon chips and fold them in with two or three gentle strokes until evenly distributed throughout the batter.
- Divide the batter evenly among the prepared muffin cups, filling each about three-quarters full. Remove the crumb topping from the refrigerator and scatter a generous amount over each muffin, pressing it on lightly so it sticks to the surface of the batter.
- Bake for 20 to 23 minutes, until the muffin tops are golden brown and a toothpick inserted into the center of a muffin comes out clean or with just a few moist crumbs attached. Do not open the oven door before the 18-minute mark.
- Remove the muffin tin from the oven and let the muffins cool in the pan for 5 minutes. Transfer them to a wire rack to finish cooling. Serve warm or at room temperature.
Notes
Make It Your Own
- Swap the chips: No cinnamon chips on hand? Mini chocolate chips or white chocolate chips make a wonderful substitute in these sourdough muffins cinnamon variations.
- Add nuts: Fold in 1/2 cup of toasted pecans or walnuts for extra crunch and a nutty richness that pairs beautifully with the cinnamon.
- Go dairy-free: Replace the butter with melted coconut oil and the milk with oat milk. The texture stays soft and the flavor is still wonderful.
- Maple glaze finish: Drizzle a simple maple glaze (powdered sugar, a splash of maple syrup, and a teaspoon of milk) over the cooled muffins for an extra layer of sweetness.
How to Make Sourdough Cinnamon Muffins with Crumb Topping
- Preheat and prep: Preheat your oven to 375 degrees F (190 degrees C) and line a standard 12-cup muffin tin with paper liners or grease it well with butter or nonstick spray.
- Make the crumb topping first: Combine the flour, brown sugar, and cinnamon in a small bowl. Add the cold cubed butter and use your fingertips or a pastry cutter to work it in until the mixture resembles coarse, pea-sized crumbles. Refrigerate until needed.
- Mix the dry ingredients: In a large bowl, whisk together the flour, baking powder, baking soda, cinnamon, and salt until evenly combined.
- Mix the wet ingredients: In a separate bowl, whisk together the sourdough discard, melted butter, eggs, brown sugar, milk, and vanilla extract until smooth and well blended.
- Combine wet and dry: Pour the wet mixture into the dry ingredients and fold gently with a spatula. Stop mixing as soon as no dry streaks remain. Overmixing leads to dense, tough muffins so a few lumps are perfectly fine.
- Fold in the cinnamon chips: Add the cinnamon chips and fold them in with just two or three strokes.
- Fill the muffin cups: Divide the batter evenly among the prepared cups, filling each about three-quarters full. Top each muffin generously with the chilled crumb topping, pressing it on very lightly so it adheres.
- Bake: Bake for 20 to 23 minutes, until the tops are golden and a toothpick inserted into the center of a muffin comes out clean or with just a few moist crumbs.
- Cool: Let the muffins rest in the pan for 5 minutes before transferring to a wire rack. This prevents the bottoms from steaming and getting soggy.
Tips for Best Results
- Use cold butter for the streusel: Warm or softened butter will make the crumb topping clump together instead of forming those perfect sandy, crunchy bits. Work quickly and keep it refrigerated until you’re ready to top.
- Do not overmix the batter: This is the most common mistake with muffins. Once the wet and dry ingredients meet, fold gently. Overworked gluten equals rubbery, flat muffins.
- Room temperature eggs and discard: Cold ingredients straight from the fridge do not blend as smoothly. Pull your eggs and sourdough discard out about 30 minutes before you begin.
Chef’s tip: If you want extra-tall, domed muffin tops, start the oven at 425 degrees F for the first 5 minutes, then reduce to 375 degrees F for the remainder of the bake time. The initial heat blast helps the tops rise dramatically before the crumb sets.
- Fill generously: Three-quarters full is the sweet spot. Too little batter and your muffins will be flat. Too much and they overflow and lose that domed crown.
Serving Suggestions
- Warm with butter: Slice one open while still slightly warm and let a pat of salted butter melt into the crumb. Pure comfort.
- Alongside a hot drink: These pair beautifully with a strong cup of coffee, a chai latte, or a simple black tea.
- As part of a brunch spread: Arrange on a wooden board with fresh fruit, yogurt, and a drizzle of honey for an effortlessly beautiful brunch setup.
- Lightly toasted next day: Pop a day-old muffin in the toaster oven for 3 to 4 minutes to revive the crunch on the crumb topping.
Storage Instructions
- Room temperature: Store cooled muffins in an airtight container at room temperature for up to 3 days. Place a sheet of paper towel under and over them to absorb any excess moisture.
- Refrigerator: They keep well in the fridge for up to 5 days, though the crumb topping will soften slightly. A quick warm-up in the microwave or oven restores much of the texture.
- Freezing: Wrap each muffin individually in plastic wrap, then place in a zip-lock freezer bag. They freeze beautifully for up to 3 months.
- Reheating from frozen: Unwrap and microwave for 45 to 60 seconds, or warm in a 350 degree F oven for 10 minutes until heated through and the crumb is slightly crisped again.
Frequently Asked Questions
Can I use active sourdough starter instead of discard?
Absolutely. Active starter works just as well. The flavor may be slightly milder and less tangy, but the texture of the muffins will be equally good.
I can’t find cinnamon chips. What should I do?
You can make a quick substitute by mixing 1/2 cup white chocolate chips with 1 teaspoon of cinnamon. It is not identical but gives you a similar warm, sweet burst in every bite.
Why did my muffins sink in the middle?
This usually happens from underbaking or opening the oven door too early. Make sure your oven is fully preheated and resist peeking until the 18-minute mark. A toothpick test is the most reliable way to check doneness.
Can I make the batter the night before?
It is best to bake the batter right after mixing. However, you can prep the dry ingredients, wet ingredients, and crumb topping separately the night before and combine them in the morning. This saves time without sacrificing rise or texture.
