It’s an easy bake for beginners, but satisfying enough for experienced bakers who want a quick win. Grab a bowl and a whisk—this one comes together fast.

What Makes This Recipe So Good

• No yeast, no rise. Baking powder and a touch of baking soda give lift, so you can go from mixing to baking in minutes.
• Perfect use for sourdough discard. The discard adds gentle tang and moisture without any sour punch.
• Cinnamon swirl that won’t sink. A simple layering technique keeps the stripe neat and pretty.
• Moist, tender crumb. Oil and sour cream (or yogurt) keep it soft for days.
• Pantry-friendly. Everything on the ingredient list is simple and easy to find.

What You’ll Need

• Sourdough discard: 1/2 cup (120 g), unfed, room temperature if possible.
• All-purpose flour: 2 cups (240 g).
• Granulated sugar: 3/4 cup (150 g) for the batter.
• Brown sugar: 1/3 cup (70 g) for the swirl (light or dark).
• Baking powder: 2 teaspoons.
• Baking soda: 1/4 teaspoon (balances the acidity of the discard).
• Kosher salt: 1/2 teaspoon.
• Cinnamon: 2 teaspoons for the swirl + 1/2 teaspoon for the batter (optional).
• Eggs: 2 large, room temperature.
• Neutral oil: 1/2 cup (120 ml), such as canola, avocado, or light olive oil.
• Sour cream or plain Greek yogurt: 1/2 cup (120 g).
• Milk: 1/4 cup (60 ml), dairy or unsweetened non-dairy.
• Vanilla extract: 2 teaspoons.
• Butter (optional, for topping): 1 tablespoon melted, to brush on top.

Step-by-Step Instructions

1. Prep your pan and oven. Heat the oven to 350°F (175°C). Grease a 9×5-inch loaf pan and line it with a parchment sling for easy lifting.
2. Make the cinnamon swirl. In a small bowl, stir together the brown sugar and 2 teaspoons cinnamon.

   Set aside.

3. Mix dry ingredients. In a large bowl, whisk the flour, granulated sugar, baking powder, baking soda, salt, and the optional 1/2 teaspoon cinnamon.
4. Mix wet ingredients. In another bowl, whisk the eggs, oil, sour cream (or yogurt), milk, vanilla, and sourdough discard until smooth.
5. Combine. Pour the wet mixture into the dry. Stir gently with a spatula until just combined. A few small lumps are fine—don’t overmix.
6. Layer the batter. Spread half the batter into the pan.

   Sprinkle all the cinnamon-sugar mixture evenly over it. Spoon the remaining batter on top and smooth gently. For a dramatic swirl, run a butter knife through the batter in two or three figure-eights.

7. Bake. Bake 50–60 minutes, until a toothpick in the center comes out clean or with a few moist crumbs.

   If the top is darkening too quickly, tent loosely with foil for the last 10–15 minutes.

8. Finish and cool. If using, brush the top with melted butter right out of the oven for sheen and softness. Cool in the pan 15 minutes, then lift out and cool fully on a rack before slicing.
9. Slice and serve. Use a serrated knife for clean slices. Serve warm or at room temperature.

How to Store

• Room temperature: Wrap tightly or keep in an airtight container for up to 3 days.
• Refrigerator: Up to 6 days, wrapped well to prevent drying.
• Freezer: Wrap slices individually and freeze up to 2 months.

  Thaw at room temperature or warm in the toaster oven.

• Reheat: 10–15 seconds in the microwave or 5 minutes in a 300°F (150°C) oven to refresh.

Health Benefits

• Reduced food waste: Using sourdough discard keeps your starter routine sustainable and less wasteful.
• Balanced sweetness: This loaf is sweet but not cloying, thanks to the slight tang from the discard.
• Calcium and protein boost: Sour cream or Greek yogurt adds a bit of protein and minerals, and helps with satiety.
• No hydrogenated fats: Neutral oils and real dairy keep the ingredient list simple and recognizable.

Pitfalls to Watch Out For

• Overmixing the batter: This leads to a tough, dense loaf. Mix just until you don’t see dry streaks.
• Cold ingredients: Very cold eggs or dairy can cause the batter to thicken unevenly. Room temperature ingredients mix more smoothly and bake more evenly.
• Too-wet swirl: Don’t add butter to the cinnamon-sugar layer; it can make the swirl sink.
• Underbaking: The swirl can make doneness tricky.

  Test in multiple spots, avoiding the cinnamon stripe where the tester may come out gooey.

• Wrong pan size: A smaller pan can cause overflow and raw centers. Stick with a 9×5-inch pan, or adjust bake time for 8.5×4.5-inch.

Recipe Variations

• Cinnamon Streusel Top: Mix 3 tablespoons cold butter, 1/3 cup flour, 1/4 cup brown sugar, and 1 teaspoon cinnamon. Crumble on top before baking.
• Glazed Finish: Whisk 1/2 cup powdered sugar with 1–2 tablespoons milk and 1/4 teaspoon vanilla.

  Drizzle over the cooled loaf.

• Nutty Swirl: Add 1/2 cup chopped pecans or walnuts to the cinnamon sugar for crunch.
• Apple Cinnamon: Fold 3/4 cup small diced apple (patted dry) into the batter. Bake closer to 60–65 minutes.
• Whole-Wheat Boost: Swap 1/2 cup all-purpose flour for whole-wheat flour. Add 1–2 tablespoons extra milk if needed.
• Dairy-Free: Use plant-based yogurt and milk; the texture stays tender.
• Pumpkin Spice Twist: Replace 1/2 cup milk and 1/4 cup of the oil with 3/4 cup pumpkin puree; use pumpkin pie spice instead of cinnamon.
• Mini Loaves or Muffins: Bake in two 5×3-inch mini pans for 30–35 minutes, or as muffins for 18–22 minutes.

FAQ

Can I use active sourdough starter instead of discard?

Yes.

Active starter works fine here. The chemical leaveners provide the rise, so you won’t get more lift from active starter, but the flavor will be similar. Use the same amount.

What if my discard is very sour?

If your discard is extra tangy, increase the sugar in the batter by 1–2 tablespoons or use vanilla yogurt instead of plain to balance the flavor.

Can I make this gluten-free?

Yes.

Use a cup-for-cup gluten-free flour blend with xanthan gum. Let the batter rest 10 minutes before baking to hydrate the starches, and check for doneness toward the end.

Why did my cinnamon swirl sink?

Usually it’s from too loose a batter or adding melted butter to the swirl. Measure flour accurately, avoid thinning the batter, and keep the swirl layer dry.

How do I know it’s done?

Look for a well-browned top and a toothpick that comes out clean from the cake portion, not the swirl.

The loaf should spring back lightly when pressed.

Can I reduce the sugar?

You can cut the granulated sugar in the batter to 1/2 cup and keep the swirl as written. The crumb will be a bit less tender but still good.

What oil is best?

Use a neutral oil like canola, sunflower, avocado, or light olive oil. Butter works too but will make the crumb slightly firmer; melt and cool it before mixing.

In Conclusion

This Sourdough Discard Cinnamon Swirl Quick Bread brings bakery-level comfort with weeknight effort.
