Ingredients

Brown Sugar (batter): Provides gentle sweetness and moisture depth for a tender crumb in the bread batter.
All-Purpose Flour: Forms the base structure of the bread with neutral flavor and versatile baking properties.
Baking Powder: Acts as the leavening agent, creating a light, airy texture without yeast fermentation.
Salt: Balances sweetness and enhances the overall flavor of the bread.
Egg: Adds richness and helps bind the ingredients together while contributing to structure.
Milk: Moisturizes the batter and creates a soft texture with a slight creamy flavor.
Melted Butter: Adds tenderness and richness, enriching the bread’s flavor and crumb.
Sourdough Discard: Leftover unfed starter adding subtle tang and complexity without requiring extra fermentation.
Cinnamon (swirl filling): Provides warm, comforting spice to the swirl for classic cinnamon bread flavor.
Brown Sugar (swirl filling): Creates a sweet, caramelized cinnamon layer that melts into the bread during baking.

Instructions

Preheat and Prepare Pan: Set your oven to 350°F (175°C) and grease a 9×5 inch loaf pan to ensure the bread doesn’t stick. This allows even baking and easy release of the finished loaf.
Mix Cinnamon Swirl Filling: Combine brown sugar and cinnamon in a small bowl until evenly mixed. This sweet, spiced mixture will be layered inside the batter to create the delicious swirl.
Combine Dry Ingredients: Whisk together flour, baking powder, salt, and remaining brown sugar in a medium bowl. Thorough mixing distributes leavening and seasoning evenly for consistent rise and flavor.
Mix Wet Ingredients: In another bowl, blend the egg, milk, melted butter, vanilla extract, and sourdough discard until smooth. This step incorporates moisture and richness while ensuring the discard mixes evenly into the batter.
Combine Wet and Dry Mixtures: Slowly fold the wet ingredients into the dry, stirring just until combined. Avoid overmixing, which can result in a tough bread. A few lumps are okay for a tender crumb.
Layer Batter and Swirl: Pour half of the batter into the prepared pan and evenly sprinkle with about three-fourths of the cinnamon sugar filling. Top with the remaining batter and sprinkle with the rest of the filling. Use a knife to gently swirl the layers to create a marbled effect without fully mixing.
Bake Until Golden: Bake the bread for 45 to 50 minutes until a toothpick inserted in the center comes out clean. The bread should be golden brown on top with a tender, moist inside.
Cool Before Serving: Allow the bread to cool in the pan for about 20 minutes, then transfer to a wire rack. Cooling helps the bread set and makes slicing easier without crumbling.

You Must Know

Do not overmix the batter; gentle folding keeps the bread soft and tender.
If your sourdough discard is particularly sour, the bread may have a slight tang; this balances beautifully with the cinnamon sugar.
Use a buttered or parchment-lined pan for easy release and neat slices.

Storage Tips

Store cooled cinnamon bread wrapped tightly in plastic wrap or an airtight container at room temperature for up to 3 days. For longer storage, freeze individual slices in a zip-top bag for up to 2 months and thaw before serving.

Serving Suggestions

This bread is delightful toasted with a pat of butter or cream cheese. Pair it with a hot cup of coffee, tea, or milk for a satisfying breakfast or afternoon snack. It also works well as a base for French toast or bread pudding.

Professional Tips

Ensure your sourdough discard is at room temperature for easier mixing and better rise.
Use a sharp knife for swirling to create gentle marbling without overmixing the cinnamon filling.
Adding a splash of vanilla extract to the wet ingredients enhances overall flavor depth.

FAQs

Can I use gluten-free flour instead of all-purpose flour?: Yes, but results may vary. Use a gluten-free flour blend designed for baking and expect slight texture changes.
Do I need to feed my sourdough discard before using?: No, this recipe uses unfed discard, which adds flavor and reduces waste without extra rising time.
Can I add nuts or raisins to the batter?: Absolutely! Fold in chopped nuts or raisins after mixing batter for added texture and flavor.
What if I don’t have brown sugar?: Light or dark brown sugar gives the best flavor, but you can substitute with white sugar plus a bit of molasses for similar richness.
How do I know when the bread is done?: Insert a toothpick in the center; it should come out clean or with a few moist crumbs, never wet batter.
Can I make this recipe dairy-free?: Yes, replace milk with your favorite plant-based milk and use a dairy-free butter alternative.
Why is the bread dense sometimes?: Overmixing the batter or expired baking powder can cause density. Mix gently and use fresh leavening for best results.
