The Best Sourdough Coffee Cake Recipe with Cinnamon Swirls

Sourdough coffee cake is the perfect marriage of light, fluffy cake and a ribbon of warm cinnamon sweetness running through each bite. Topped with a buttery brown sugar crumble and a drizzle of luscious vanilla glaze, this homemade beauty will have your kitchen smelling irresistible in no time. Trust me, you’ll want a second slice—maybe even a third!

Growing up, coffee cake was a staple at family breakfasts. But once I started experimenting with a sourdough starter, this version stole the show. That tangy flavor from the starter gives the cake such depth and balances the sweetness so beautifully. Whether you’re looking to put your starter to work or just need a crowd-pleasing treat for brunch, this is your new go-to recipe.

Why This Sourdough Coffee Cake Is So Irresistible

• The sourdough starter gives this cake an extra tender crumb with a slight tang that complements the sweetness.
• A rich cinnamon and brown sugar topping melts into the batter, creating a caramelized layer of flavor.
• It’s quick and easy: Just 10 minutes of prep before it’s oven-ready!
• The buttery glaze drizzled on top adds moisture and a touch of indulgence to every bite.
• Perfect for any occasion—from Sunday mornings to special celebrations.

Essential Ingredients for Perfect Sourdough Coffee Cake

While this recipe doesn’t call for a long list of ingredients, each one plays a key role in creating the magic. Let’s highlight a few:

• Sourdough Starter: The star of the show! Use an active, room-temperature starter for the best flavor and texture. If you don’t have a starter, you can create one in just a few days by mixing equal parts flour and water and letting it ferment.
• Brown Sugar: This is how we achieve that signature rich, caramelized flavor in the cinnamon topping. You can substitute coconut sugar if you’re aiming for a healthier twist.
• Ground Cinnamon: It’s the heart of any great coffee cake. Opt for high-quality cinnamon—Saigon cinnamon is especially fragrant!
• Oil: Neutral oils like vegetable or canola keep the cake moist and tender. For a slightly nutty flavor, try melted coconut oil or light olive oil.

Ingredients for Sourdough Coffee Cake

• cooking spray
• 2 cups sourdough starter, at room temperature
• 2 cups all-purpose flour
• 1 cup white sugar
• 2/3 cup oil
• 2 teaspoons baking powder
• 1 scant teaspoon salt

How to Make Sourdough Coffee Cake

1. Preheat your oven to 350 degrees F (175 degrees C) and grease a 9×13-inch baking pan with cooking spray.
2. In a large bowl, mix the sourdough starter, flour, white sugar, oil, baking powder, salt, and cinnamon. Use an electric mixer to beat until the batter is smooth and thick. Pour the batter evenly into your prepared pan.
3. In a separate bowl, combine the brown sugar, softened butter, and cinnamon until it’s evenly moistened and crumbly. Sprinkle the topping generously over the cake batter.
4. Place the pan in the oven and bake for about 30 minutes, or until a toothpick inserted into the center of the cake comes out clean. The top should be golden brown.
5. While the cake is baking, whisk together the melted butter, milk, and vanilla extract to make the glaze. Once the cake is hot out of the oven, drizzle the glaze over the top for a glossy finish.

Expert Tips for the Best Sourdough Coffee Cake

• Room Temperature Ingredients: Make sure your sourdough starter and melted butter are at room temperature for easy mixing and even baking.
• Don’t Overmix: As tempting as it may be to stir out every lump, overmixing will make your cake dense. Stop when the batter is just combined.
• Opt for Fresh Spices: If your ground cinnamon has been sitting in the cabinet for over a year, it might have lost its punch. Fresh spices make a world of difference!
• Make Ahead: You can bake the cake a day in advance and store it covered at room temperature. Add the glaze just before serving.
• Freezing: This cake freezes beautifully! Let it cool completely and wrap individual slices tightly before freezing for up to 2 months.

Delicious Sourdough Coffee Cake Variations

• Nutty Crunch: Add chopped pecans or walnuts to the cinnamon-brown sugar topping for extra texture and flavor.
• Berry Bliss: Fold a cup of fresh or frozen (and thawed) blueberries into the batter for a fruity twist.
• Lower Sugar: Swap half of the white sugar in the batter with unsweetened applesauce to reduce overall sweetness while keeping it moist.

Sourdough Coffee Cake FAQs

Can I use discard sourdough starter for this recipe?

Yes! This recipe is perfect for using up discard sourdough starter since the tangy flavor pairs beautifully with the cinnamon and sugar.

What kind of oil works best?

Neutral oils like vegetable or canola are great, but you can experiment with melted coconut oil for added flavor!

How do I know when the cake is fully baked?

The top should be golden brown, and when you insert a toothpick into the center, it should come out clean or with just a few moist crumbs.

Can I make this gluten-free?

While I haven’t tested it, you can try substituting a 1-to-1 gluten-free flour blend for the all-purpose flour.

This sourdough coffee cake is a recipe I come back to time and time again—and I know you will too! The tender crumb, luscious cinnamon flavor, and that glossy glaze combine to make every bite unforgettable. Have you tried baking with sourdough before? Let me know in the comments!
