One of the best ways to turn a normal morning into a special occasion is to bake a sweet treat.
This sourdough coffee cake is one of my go-to recipes because it suits a holiday just as well as a Sunday morning.
A coffee cake is simply a cake traditionally served with coffee, typically with a crumb topping or perhaps a drizzle of icing.
This sourdough coffee cake is light and sweet, swirled in the center with a gooey cinnamon filling. The same filling used in the center is also used as a crumble topping, which I find to be both delicious and efficient.
It’s a great recipe for using up sourdough discard, and that classic tangy flavor is the perfect balance with a buttery, crisp, cinnamon crumble.
Served with cold milk or hot coffee, this cinnamon coffee cake is a big family favorite breakfast, right up there with sourdough cinnamon rolls and sourdough banana bread.
Why You’ll Love Sourdough Coffee Cake
Delicious go-to – It’s sweet, but not too sweet! The spice of the cinnamon and the warm, buttery flavors of the vanilla cake work well with the sourdough tang. Use discard for bolder sourdough flavor, or active starter for a milder tone.
Year-round favorite – Coffee cakes are always good, and cinnamon is a flavor that’s a hit all year. It’s light enough for spring and summer while bursting with all the warm, cozy flavor for fall and winter.
Sourdough discard – Coffee cakes are one of my favorite ways to use sourdough discard. Discard adds so much moisture and flavor! If you’re interested in more ways to incorporate your discard into breakfast, I compiled a list of 20+ sourdough discard breakfast recipes just for that purpose!
Ingredients
Oil: Any neutral oil will work, I prefer avocado oil. Coconut oil would be melted and slightly cooled for use in the cake batter.
Brown sugar: Combined with cane sugar to sweeten the cake and topping, brown sugar gives a deep molasses flavor and produces a golden color in the bake.
Sourdough starter: For this recipe, you can use active starter or discard.
All-purpose flour: I love all-purpose flour for this recipe, as it gives consistent results and maintains a tender and light crumb.
A full ingredient list with exact amounts can be found in the recipe card below.
How to Make Sourdough Coffee Cake
Step 1: Preheat the oven to 350 degrees Fahrenheit and grease a 9×13-inch baking dish. In a medium-sized mixing bowl, stir the cinnamon crumble ingredients (melted and cooled butter, brown sugar, cinnamon, and flour) until completely combined. Set aside.
Step 2: In a large mixing bowl, cream the oil, cane sugar, and brown sugar until smooth.
Step 3: Add the eggs, vanilla, sourdough starter, and milk. Mix well.
Step 4: In a separate bowl, whisk the salt, baking soda, and flour until combined. Add the dry ingredients to the wet ingredients and fold with a spatula until just combined. Don’t overmix the batter.
Step 5: Pour half of the coffee cake batter into the prepared baking dish. Sprinkle half of the crumble mixture evenly on top. Pour the remaining cake batter over the crumble, then sprinkle the rest of the crumble mixture over the top of the batter.
Step 6: Bake in the preheated oven for 40-50 minutes. The edges will start to turn golden, and a toothpick inserted should come out clean. Cool completely before slicing and serving.
Long Fermented Version
Note: The cinnamon filling won’t be fermented for this recipe, but the batter can be fermented. Keep in mind that a fermented cake batter typically results in a denser, less fluffy cake.
Step 1: Combine the oil, sugars, eggs, sourdough starter, milk, and flour. Cover with a tight lid or plastic wrap (to prevent a hard crust from forming) and leave at room temperature for 8 to 24 hours.
Step 2: After the fermentation time, preheat the oven to 350 degrees Fahrenheit and grease a 9×13 baking dish.
Step 3: In a medium mixing bowl, stir the cinnamon crumble ingredients (melted and cooled butter, brown sugar, cinnamon, and flour) until completely combined. Set aside.
Step 4: Add the remaining cake ingredients (vanilla, salt, and baking soda) to the fermented cake batter. Mix briefly, just until combined. Be careful not to overmix.
Step 5: Pour half of the cake batter into the prepared baking dish. Sprinkle half of the crumble mixture evenly on top. Repeat with the other half of the cake batter and crumble mixture.
Step 6: Bake in the preheated oven for 40-50 minutes. The edge of the cake will start to turn golden brown, and a toothpick inserted should come out clean. Cool completely before slicing and serving.
Tips
- You can make the quick version the day of, or start the day before to allow it to ferment. Fermentation not only helps break down the grain and reduce phytic acid, but it also adds a stronger tangy flavor. Keep in mind that a fermented cake batter will typically yield a denser cake, so you’ll lose some of the light, fluffy texture.
- A stand mixer will make working with the long-fermented batter much easier.
- You can make this recipe with active sourdough starter or discard. Either will work since we are using a leavening agent.
- You can make this dairy-free by using a neutral oil, rather than butter, in the crumb topping. Also, swap out the milk for almond or coconut milk.
- If the flour isn’t being fermented, I sometimes use einkorn flour instead of all-purpose for easier digestion.

How to Serve Sourdough Coffee Cake
- Serve for breakfast or dessert with a strong cup of coffee or a glass of milk.
- Serve alongside a zucchini frittata for a fabulous brunch.
- Pair it with a spiced chai ice cream in the fall, or even a honey lavender ice cream in the summer.
- If you make this coffee cake dairy-free, you can also pair it with this dairy-free pumpkin spice ice cream!
Recipe FAQs
No, it’s not made with coffee, but it’s typically made for coffee! A coffee cake is topped with a crumble, whereas a traditional cake is frosted.
This sourdough coffee cake tastes best when eaten on the same day. You can store it in an air-tight container at room temperature for up to three days or in the fridge for up to two weeks.
You can also freeze the cake for up to three months. It’s helpful to cut into individual portions and freeze them individually. Wrap with plastic wrap or parchment paper in a freezer-safe container. Thaw and gently reheat for a few minutes before serving.
This is purely preference! Coffee cake makes a delicious and special breakfast, but it can easily be served for dessert, as well!
You can use all-purpose or einkorn flour. When you are substituting einkorn flour, you will need slightly more einkorn because it absorbs less liquid than all-purpose. The batter tends to be wetter, but the results are delicious either way.
Here are some common reasons for a cake sinking in the center.
The oven was not preheated.
The batter was overmixed. Mix just until it comes together. There will be lumps in the batter, and that’s okay.
The oven door was opened too often, causing the oven temperature to fluctuate.
The baking soda may be old. It’s recommended to replace your baking soda every 3-6 months if it’s stored in an open container.
Sometimes bumping your baking dish or setting it down too roughly can cause the center of the cake to deflate.

What a delicious way to use up some discard. Very moist and flavorful. Great R&D! Thank you for sharing.
If you want to see an amazing story of sourdough, Google Ina Garten (Food Network’s The Barefoot Contessa) tour of the Poilane Bakery in Paris during the 2024 Olympics. This bakery has been there since 1932 and is still nurturing the same sourdough starter! You can almost smell the wonderful items in this bakery.
Is the cinnamon filling supposed to have the 1 cup of flour? I made it this weekend and everything was great except that cinnamon layer was basically just a layer of dry flour. I thought it was odd when I was making it but went ahead with how it was written anyway and it didn’t turn out right. I’m not sure if it should just be the cinnamon and sugar or if there’s another ingredient missing for the filling.
This is better than any coffee cake that you can buy!
The ingredients are flipped for the filling and the crumb topping FYI.
Thank you for the recipe.
The crumb became a paste on top. All melted after baking. Followed the recipe to the gram. Not sure why it didn’t work
My family DEMOLISHED this cake within 24 hours. It’s not just for breakfast…they ate it at ALL hours of the day. Not too sweet, tender crumb, beautiful swirl on the inside, and I got to use some of my sourdough discard…this recipe is coffee cake perfection! You will impress yourself and others when you make it. Thank you Lisa!
Can ingredients starting at sourdough down be fermented overnight before finishing and baking cake?
Yes.
I made these last night and they are so greasy using coconut oil. Is there something I did wrong? I had to melt my coconut oil and then when I mixed all my ingredients, the coconut oil all clumped up and became solid again so when they baked I guess all the coconut oil just became a mess. Is this normal?
If your other ingredients were very cold, that could be the reason why it clumped up. I would try using lukewarm ingredients and room temperature ingredients before adding your coconut oil.
So good. I have made it twice and my family and co-workers loved it.
I love the long ferment version of this recipe but wish it were written out on the recipe card version. It’s so hard to follow in the blog.
I agree—the long fermented version was SO GOOD, but I accidently added the vanilla and the salt while I was scrolling back and forth between the blog instructions and the recipe card. The final product still turned out great, but having the long fermented version as a recipe card would be super helpful!
