👩🍳 How to Make Sourdough Cinnamon Swirl Loaf
Step 1: Feed Your Starter
Make sure your sourdough starter is active and bubbly. Feed it 4–6 hours before baking for best results.
Step 2: Make the Dough
In a large mixing bowl, combine the sourdough starter, warm milk, butter, sugar, and salt. Gradually add the flour, mixing until a soft dough forms. Knead for about 8–10 minutes until smooth and elastic.
Step 3: Bulk Fermentation
Place the dough in a lightly oiled bowl, cover it, and let it ferment at room temperature for 6–8 hours, or until doubled in size.
Step 4: Prepare the Cinnamon Filling
Mix the melted butter, brown sugar, and cinnamon in a small bowl until it forms a paste.
Step 5: Shape the Loaf
Turn the dough out onto a lightly floured surface and roll it into a rectangle (about 10×12 inches). Spread the cinnamon mixture evenly over the surface. Roll up the dough tightly from the short side and pinch the seam closed.
Place the rolled dough into a greased loaf pan, seam-side down.
Step 6: Proof the Loaf
Cover and let it proof for another 1–2 hours, or until the loaf has risen about 1 inch above the pan.
Step 7: Bake
Preheat your oven to 375°F (190°C). Brush the top with egg wash if desired. Bake for 40–45 minutes, or until golden brown and the internal temperature reaches 190°F (88°C).
Step 8: Cool and Serve
Let the loaf cool completely before slicing. Serve warm with butter, honey, or a light dusting of powdered sugar.
📝 Notes
- For a sweeter loaf, sprinkle extra cinnamon sugar over the top before baking.
- You can substitute whole milk with almond milk or oat milk for a dairy-free version.
- Leftovers store well at room temperature for up to 3 days, or can be frozen for up to 2 months.
- If your kitchen is cold, proof the dough in a slightly warm (but turned off) oven.
❓ FAQs
Q: Can I make this with discard sourdough starter?
A: You can, but it won’t rise as well. It’s best to use an active, bubbly starter.
Q: How can I make this loaf more indulgent?
A: Add a swirl of raisins or chopped pecans with the cinnamon mixture for extra texture and flavor.
Q: My swirl separated while baking — what happened?
A: Too much filling or not rolling tightly enough can cause gaps. Try reducing the butter slightly next time.
Q: Can I use bread flour instead of all-purpose?
A: Absolutely. It will give you a chewier texture and slightly higher rise.
