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 โ€“ 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 โ€“ 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 โ€“ 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

jars of ingredients spread out on a countertop.

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

brown sugar, cinnamon, melted butter and flour in a glass bowl.

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 isnโ€™t being fermented, I sometimes use einkorn flour instead of all-purpose for easier digestion.

How to Serve Sourdough Coffee Cake

Recipe FAQs

Is coffee cake made with coffee?

No, it’s not made with coffee, but it’s typically madeย forย coffee! A coffee cake is topped with a crumble, whereas a traditional cake is frosted.

How should I store my leftovers?

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.

Is coffee cake a breakfast or dessert?

This is purely preference! Coffee cake makes a delicious and special breakfast, but it can easily be served for dessert, as well!

What type of flour can I use to make this recipe?

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.

My cake sunk in the middle. What went wrong?

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.ย

    Delicious! My four year old begs to help me make this because he loves it so much!

    Not as pictured and the crumb all sunk. This recipe is awful.

    1. Lisa Bass says:

      I am sorry you did not like this recipe! I hope you try it again because it should not sink.

  3. Lisa says:

    So yummy! But the crumb is so hard to work with. It does not crumble AT ALL, and sinks to the bottom while baking, which is always so disappointing.

  4. Gina says:

    I liked the original recipe much better. I never had a problem with it. I went to make this again and noticed that it had changes. All the cinnamon crumble had sucked to the bottom and nothing left on the top. I was disappointed. I read further and saw the original recipe. I am going to have to reprint it and add to my recipe book do I will not loose it. Why did you change it?

    Great recipe but it was even better before you updated it. lost count of how many times I’ve made this. Very delicious.

    Overall a good coffee cake. Issue is with the crumble topping. The way it is here produces a thick batter- like consistency and does not crumble. It would be better if the butter was cold and worked /cut in. That would give it the crumble texture.
