Sourdough Cinnamon Raisin Loaf: The Recipe My Neighbor Keeps Knocking on My Door For

My neighbor started knocking on my door within a week of my first cinnamon raisin loaf. Not for a slice — for the whole recipe, written down, because his wife kept asking where he’d been disappearing to on Saturday mornings.

What Makes This Loaf Different

Most cinnamon raisin sourdough recipes either drown the crumb in sugar or turn the raisins into hard little pellets by the time the bake finishes. This version keeps the tang of a real sourdough base intact and treats the cinnamon swirl and raisins as an addition, not a replacement for good bread technique.

What You’ll Need

• 500g bread flour
• 350g water (70% hydration)
• 100g active starter
• 10g salt
• 2 tbsp cinnamon, mixed with 3 tbsp brown sugar
• 150g raisins, soaked in warm water for 15 minutes and drained

The Raisin Trick That Actually Matters

Soaking raisins before you fold them in is non-negotiable. Dry raisins pull moisture straight out of the surrounding dough during the bake, leaving you with dense, gummy patches around every raisin and a crust that never quite crisps. Fifteen minutes in warm water plumps them back up so they bake evenly instead of stealing hydration from the crumb.

Step by Step

• Mix and autolyse: Combine flour and water, rest 30 minutes before adding starter and salt.
• Bulk ferment: 4-5 hours at room temperature with 4 sets of stretch and folds in the first two hours.
• Add the swirl: On your final fold, gently laminate the dough, sprinkle the cinnamon-sugar mix and drained raisins evenly, then roll it back into shape.
• Shape and proof: Shape into a boule or batard, then cold retard overnight in the fridge (8-12 hours).
• Bake: 450°F in a preheated Dutch oven, lid on for 20 minutes, lid off for 20-25 minutes until deeply browned.

I add the cinnamon-sugar and raisins during lamination rather than mixing them straight into the dough — it keeps the swirl visible when you slice, instead of muddying the whole crumb brown.

Why the Swirl Holds Together

The reason lamination beats mixing here comes down to gluten structure. Folding cinnamon-sugar into an already-developed dough sheet keeps the gluten network mostly intact around it, so the dough still rises properly. Mixing sugar and raisins directly into the dough from the start disrupts gluten formation across the whole loaf, which is part of why so many cinnamon raisin sourdough attempts come out dense.

Cinnamon itself has mild antimicrobial properties that can slow yeast activity if it touches the dough directly in large quantities. Keeping it contained to the swirl layer, rather than distributed evenly, sidesteps that problem entirely — another reason lamination outperforms a straight mix-in.

Storing and Reheating

This loaf keeps better than a plain sourdough thanks to the sugar content, which holds moisture longer. Wrapped well, it’s good at room temperature for 3-4 days. Past that, slice and freeze — toast straight from frozen and the cinnamon swirl actually gets more fragrant as it warms.

Sourcing Good Raisins

I’ve gone through more raisin brands than I’d like to admit trying to find ones that don’t turn leathery in the oven. Sun-Maid’s sun-dried raisins have been the most consistent for me — plump, evenly sized, and they hold their shape through the bake instead of shriveling into little raisin bullets.

What Works and What Doesn’t

What works

• Soaking raisins before adding them — every single time, no exceptions
• Laminating the swirl in rather than mixing it into the base dough
• A full overnight cold retard, which lets the cinnamon flavor mellow into the crumb instead of sitting on top of it

What doesn’t

• Adding dry raisins straight from the bag — guaranteed gummy pockets
• Too much cinnamon-sugar — more than 3 tablespoons total and it burns before the crust finishes developing
• Skipping the cold retard — the swirl tastes flat without it
