If you maintain a sourdough starter, you know the challenge of managing regular discard–and the guilt of throwing it away. Sourdough cinnamon sugar quick bread transforms that discarded starter into a tender, naturally tangy quick bread with a delicious cinnamon-sugar streusel. Unlike yeasted breads that require overnight fermentation, this recipe comes together in under an hour, making it perfect for using up starter between regular feedings.
How to Make Sourdough Cinnamon Sugar Quick Bread
This quick bread requires minimal mixing and yields a moist crumb with subtle sourdough flavor balanced by warm cinnamon and brown sugar. The entire process takes about an hour from start to finish.
Ingredients
- 1 cup sourdough starter discard (unfed is fine)
- 1 3/4 cups all-purpose flour
- 3/4 cup sugar
- 1/2 cup neutral oil
- 2 eggs
- 1 teaspoon vanilla extract
- 1 1/2 teaspoons baking powder
- 1/2 teaspoon salt
- Cinnamon-sugar streusel: 1/4 cup brown sugar, 1 teaspoon cinnamon, 2 tablespoons melted butter
Method
Preheat and prepare your pan
Heat your oven to 350 degrees Fahrenheit. Grease a loaf pan thoroughly with oil or butter, or line it with parchment paper for easy removal. This prevents sticking and ensures clean edges on your finished bread.
Combine wet ingredients
In a large mixing bowl, whisk together the sourdough discard, oil, eggs, and vanilla extract until well blended. The mixture should be smooth and uniform, with no streaks of starter visible.
Mix dry ingredients separately
In a separate bowl, whisk together the flour, sugar, baking powder, and salt. Combine thoroughly to distribute the leavening agent evenly, which ensures consistent rise throughout the bread.
Fold wet and dry together
Pour the dry mixture into the wet mixture and fold gently with a spatula until just combined. Do not overmix–some small lumps are fine. Overmixing develops gluten and results in a tough, dense crumb.
Create the streusel topping
In a small bowl, mix the brown sugar and cinnamon together. Drizzle in the melted butter and stir until the mixture resembles damp sand with visible cinnamon-sugar clusters.
Assemble in the pan
Pour half the batter into your prepared loaf pan and smooth the surface. Sprinkle half the cinnamon-sugar streusel over the batter, then add the remaining batter on top. Finish with the remaining streusel, pressing gently so it stays in place.
Bake until golden
Place in the preheated oven and bake for 45-50 minutes, until a toothpick inserted in the center comes out with just a few moist crumbs. The top should be deep golden brown. If it’s browning too quickly, tent loosely with foil for the final 15 minutes.
Cool before serving
Remove from the oven and let the bread cool in the pan for 15 minutes. Run a thin knife around the edges and turn out onto a wire rack to cool completely. This allows the structure to set and makes slicing easier.
- Room-temperature discard incorporates more smoothly than cold starter. Remove your discard from the fridge 30 minutes before baking for best results.
- If your bread is browning too fast on top, tent with aluminum foil starting at the 30-minute mark to prevent burning while the interior finishes cooking.
- Wrap cooled bread tightly in plastic wrap or store in an airtight container for up to 4 days. This quick bread actually improves slightly as it sits, developing deeper sourdough flavor.
What to Look For in Quick Bread Baking Equipment
- Loaf Pan Material and Size: Standard loaf pans come in glass, ceramic, and metal. Metal pans conduct heat most evenly and produce the best browning; glass and ceramic brown edges faster. A standard 9×5-inch or 8×4-inch pan is essential for this recipe.
- Mixing Bowl Capacity: Large mixing bowls (3-4 quarts) prevent splashing when folding wet and dry ingredients together. Stainless steel bowls are durable and temperature-neutral, while glass allows you to see ingredient distribution.
- Cooling Rack Support: A sturdy cooling rack elevates bread away from the counter surface, allowing air to circulate underneath for even cooling. This prevents the bottom from steaming and becoming soggy.
- Testing and Measurement Tools: A reliable toothpick or cake tester indicates doneness, while dry measuring cups and a kitchen scale ensure accurate ingredient ratios. Precision prevents common baking failures.

Frequently Asked Questions
Can I use fed sourdough starter instead of discard?
Yes, fed starter works well, though you may want to reduce the baking powder slightly since active starter contains more leavening power. The bread will rise slightly more, but results remain tender and delicious. Unfed discard is the most reliable option for consistent results.
Why does my quick bread sink in the middle?
This usually indicates underbaking or excessive oven temperature. Check that your oven temperature is accurate using an oven thermometer, and insert a toothpick into the center–the bread should be done when only a few moist crumbs cling to it. Overbaking is rare with quick breads; underbaking is the typical culprit.
How do I store sourdough cinnamon quick bread?
Once completely cooled, wrap tightly in plastic wrap or store in an airtight container at room temperature for up to 4 days. The bread actually becomes more flavorful after a day. For longer storage, wrap well and freeze for up to 3 months.
Can I add nuts or chocolate to this recipe?
Absolutely. Fold 1/2 to 3/4 cup of chopped walnuts, pecans, or chocolate chips into the batter after mixing wet and dry ingredients. These additions don’t significantly affect baking time and create delicious variations on the classic recipe.
What if I don’t have sourdough discard on hand?
This quick bread relies on the sourdough discard’s moisture and slight tanginess. Substituting with regular flour and buttermilk won’t give the same result. If you don’t have discard available, save this recipe for your next feeding cycle when you have plenty.
