How to Make Irresistible Sourdough Coffee Cake
Step 1. Start by preheating your oven to a temperature suitable for baking. This step ensures that when you’re ready to place your coffee cake in the oven, it begins cooking evenly right away.
Step 2. In a mixing bowl, combine the sourdough starter and vegetable oil. Use a whisk to blend these two ingredients until they’re well combined. The starter should add a nice tangy flavor and a bit of moisture that enhances the overall texture of the cake.
Step 3. Next, add the large egg to the mixture. Whisk everything together until the egg is fully incorporated. You want a smooth consistency, so ensure there are no streaks of egg visible in the batter.
Step 4. Slowly incorporate the all-purpose flour, granulated sugar, salt, baking soda, and one teaspoon of ground cinnamon into the bowl. Mix gently but thoroughly, taking care not to over-mix. You’re aiming for a batter that is just combined, with a few small lumps remaining, which will provide a tender texture to your cake.
Step 5. In a separate small bowl, make the swirl mixture by combining the brown sugar and one teaspoon of ground cinnamon. This will create the sweet and spicy layer within the cake, adding depth to each bite.
Step 6. Grease your baking pan and pour half of the batter into it, spreading it evenly across the bottom. This layer serves as the base where the swirl will be added, and it’s important to ensure it’s even for the best results.
Step 7. Sprinkle the swirl mixture evenly over the batter in the pan. This adds a sweet contrast to the cake and will melt into the batter as it bakes, creating a delightful flavor surprise.
Step 8. Carefully spoon the remaining batter over the swirl mixture. Spread it out gently, covering the brown sugar mixture completely. This helps to trap the flavorful swirl inside, while the top layer cakes beautifully during baking.
Step 9. To prepare the crumble topping, combine the brown sugar, melted unsalted butter, and one tablespoon of flour in a bowl. Mix until crumbly, ensuring the butter is evenly distributed throughout the sugar and flour.
Step 10. Sprinkle the crumble mixture evenly over the top of the batter in the pan. This will create a delightful crunchy finish once the coffee cake has baked, adding texture and sweetness.
Step 11. Place the pan into the preheated oven. As it bakes, keep an eye on the cake and look for a golden-brown color on the top, indicating it’s ready. The cake should feel firm but springy to the touch when it’s done.

Pro Tips for Best Results
- Make sure your sourdough starter is well-mixed before using, as this ensures even flavor throughout the cake.
- Room temperature ingredients blend more easily, so let your egg sit out for a bit before mixing.
- Avoid over-mixing to keep the cake tender. The goal is to combine the ingredients without developing the gluten in the flour too much.
Common Mistakes to Avoid
- Using Cold Ingredients: Cold eggs or starter can lead to uneven mixing. Always use room-temperature ingredients to achieve a consistent batter.
- Over-Mixing the Batter: Overworking the batter can produce a dense cake. Mix just until combined to keep the texture light and fluffy.
- Not Preheating the Oven: Skipping preheating can affect the baking time and texture. Ensure the oven is properly heated before placing the cake inside for even baking.
- Ignoring the Swirl Layer: Not adding the swirl can lead to missing the cake’s depth of flavor. Always remember this step for a well-rounded taste.
- Using the Wrong Baking Pan Size: A pan that’s too small can overflow, while a too-large pan may dry the cake out. Stick with the recommended size for best results.
- Cutting Too Soon: Allow the cake to cool slightly before slicing. This ensures it holds its shape and makes for cleaner cuts.
Variations & Substitutions
Consider adding a handful of nuts for added crunch or swapping the ground cinnamon with another spice like nutmeg for a different flavor profile. You can also reduce the sugar slightly for a less sweet, more balanced taste.
Storage & Reheating
Store leftover sourdough coffee cake at room temperature in an airtight container for up to two days. If you need to keep it longer, refrigerate it, where it can last about a week. For longer storage, consider freezing slices in a freezer-safe bag for up to three months. To reheat, simply warm in the oven or microwave, so it regains its tender texture.
