Cinnamon Swirl Raisin Sourdough

This loaf took me three tries to finally get right… and I can confidently say it was 100% worth it.

We made this cinnamon swirl raisin sourdough multiple times over Christmas break, and every single loaf disappeared faster than the last. It’s slightly sweet, incredibly nostalgic, and one of those recipes that feels special enough for the holidays, but honestly good enough to make all year round.

Warm, cozy, and perfectly balanced, this has quickly become a favorite in our house.

What You’ll Need (Makes 12 Brownies)

Levain

  • 50g sourdough starter

  • 50g flour

  • 50g water

Mix together and let rise until doubled, about 4–6 hours.

Dough

Once the levain has doubled, add the entire mixture to:

  • 425g flour

  • 325g water

  • 10g salt

Mix until shaggy and let rest briefly. Then complete 3 rounds of stretch and folds, adding ¼ cup raisins during the final fold.

Cover with a damp towel and let rest for 4 hours.

Cinnamon Swirl

Turn the dough out onto a lightly floured surface and gently stretch it into a rectangle, being careful not to deflate the air bubbles.

Mix together:

  • ¼ cup butter (I used grass-fed)

  • 3 tsp cinnamon

  • ¼ cup sugar of choice (we used monkfruit sugar)

Spread the cinnamon mixture evenly over the dough, leaving about 1 inch around the edges.

Fold the dough like a letter:

  • Right over left

  • Left over right

  • Bottom to top

  • Top to bottom

Place seam-side down into a well-floured banneton.

Cold Proof (IMPORTANT)

Refrigerate for at least 3 hours or overnight, but no longer than 8 hours.

This step is crucial,it keeps the butter mixture from melting out during baking (learned that the hard way LOL).

Bake

Preheat your oven to 450°F with your Dutch oven inside.

Bake straight from the fridge:

  • 30 minutes covered

  • 20 minutes uncovered

Let cool completely (or as long as you can wait), slice, and enjoy.

If you make this, please let me know! Ryan and I have been eating it on repeat over here, and it never gets old.

Happy baking 🤪🫶
