or sourdough bakers, quick breads are the perfect "low-stress" way to use up starter discard. While most people default to banana or nut breads, you can actually create something much more decadent. By stripping out the fruit and focusing on the perfect balance of cinnamon, sugar, and vanilla, you get a loaf that tastes exactly like a fresh Mexican Churro.
The Inspiration
The idea for this loaf came after a breakfast trip to Kneaders Bakery and Cafe. They were sampling their Churro Sweet Bread, and I knew I had to recreate that flavor profile using our signature sourdough tang.
By combining elements of a classic copycat recipe with Lisa Boone’s sourdough vanilla cake and our own Banana Zucchini Nut Bread, we’ve developed a quick bread that is tender, spiced, and incredibly addictive.

Why Sourdough Quick Breads?
Beyond the incredible flavor, using sourdough discard in quick breads offers a unique combination of nutrient bioavailability and convenience. It’s the best of both worlds: the speed of a cake with the depth of a fermented grain.

Jo, we redid the recipe with your questions in mind. Hopefully, you were able to make this before now; sorry for the delay
Hello. There are two amounts of butter, sour cream and milk that don’t appear in the method. Are they meant to be used?
Butter is in recipe twice. Is that an error?
You mention needing a cup of milk and a half cup of sour cream but don’t include where to add that in the steps.
I am assuming with the liquids.
