I’m pretty excited about this recipe. I have a soft spot for raisin toast, having grown up on that red-packaged Sunmaid Raisin Bread (so good with butter…); and have been wanting to make a sourdough raisin loaf for quite awhile now. But not just a plain raisin loaf: a cinnamon-swirled raisin loaf, because what’s better than slowly unraveling and eating a piece of swirly carbs for breakfast? Well, maybe French toasting said swirly carb, but we’re getting ahead of ourselves.

So anyways, this loaf took me a few tries to get right. At first I used a cinnamon-butter paste for the swirl, but this left me with gaps (I think the butter generated too much steam during baking) and the texture was too heavy. Egg wash turned out to be a much better solution. The folding technique I first saw on Bake Street, and I love it! The swirl is encased within the loaf and makes for a really striking presentation. I had to try a couple times to work out the proper dimensions for my pan, but in the end I’m really happy with the result.

A few notes:

• There’s no beating around the bush: this loaf takes time. I like having this loaf for breakfast, so I will make the levain when I get up in the morning, mix the dough early afternoon, shape the bread right before going to bed, and bake first thing the next morning. Keep in mind that the health of your starter and your environment play a big part in fermentation times, so always “watch the dough and not the clock.” If you follow me on Instagram, I have a story highlight called “Swirl Bread” that goes through the entire process. This will hopefully give you some visual cues as to how your dough should look at each stage.
• The base dough for this bread is the sourdough Hokkaido milk bread that I’ve used a few times on this site before. If you haven’t tried this style of bread before, I highly recommend reading through those posts for more tips and tricks.

Sourdough Cinnamon Raisin Swirl Bread

Makes one loaf (I highly prefer a 9x4x4 Pullman Pan for the nicest shape, but a regular 9×5 loaf pan works too)

Ingredients

For the levain

• 18g starter (100% hydration)
• 31g milk
• 57g bread flour

• Mix and ferment at room temperature until ripe (mine is usually ready in 4-6 hours, but it depends on the strength of your starter). When ready it should be more than doubled in volume, puffy, and domed. You should see large bubbles if you pull back the top.

For the final dough:

• 284g bread/AP flour (I use half and half)
• 46g sugar
• 21g milk powder
• 53g egg (about 1 large)
• 104g milk
• 88g cream
• All of the levain
• 6g salt
• 52g unsalted butter, at cool room temperature
• 100g raisins

For the filling:

• 100g brown sugar
• 1 Tbsp ground cinnamon
• 1 Tbsp arrowroot powder or cornstarch
• Pinch of salt
• One egg, whisked with a bit of water or milk

Method

1. Mix together all final dough ingredients except the salt, butter, and raisins until just combined. Cover and autolyse (rest) for 45-60 minutes.
2. Add salt, and knead dough (with the dough hook attachment if using a stand mixer) until gluten is moderately developed (I use speed 3-4 on a KA mixer). The dough will start out sticky and rough but should gradually come together and feel quite smooth and stretchy. Turn the mixer to low and add butter about a tablespoon at a time, incorporating each batch before adding the next. Turn the speed back up and continue kneading until the gluten is very well developed and the dough passes the windowpane test as demonstrated here. The dough should be smooth and supple (and quite lovely to handle!). This will take quite some time, especially if done by hand. Consider it your arm workout for the day! Mix in the raisins just until incorporated.
3. Transfer dough to a clean and lightly oiled bowl, cover, and bulk rise at room temp for 2 hours. The dough will be noticeably expanded, but not doubled. Fold, cover tightly with plastic wrap, and refrigerate overnight (or at least 6 hours, and up to 24).
4. When ready to shape, mix together the filling ingredients and prepare the egg wash. Line a loaf pan (I prefer a Pullman pan) with parchment and lightly grease. Take the dough out of the refrigerator and transfer to a lightly floured surface. Roll into a large rectangle about 10″ x 15″, doing your best to maintain an even thickness (the more accurate your shape, the better your swirl will look at the end).
5. Brush the rectangle with an even coat of egg wash and sprinkle on about half the cinnamon-sugar mixture. Go all the way to the edges and gently press to adhere.
6. Fold in the long edges so they meet at the middle, like you are closing the shutters on a window. You should have a long, skinny rectangle about 15″ x 5″. Repeat the egg wash and cinnamon-sugar process, again going all the way to the edges.
7. Starting with the short end closest to you, roll the rectangle into a tight log. Transfer, seam side down, to the prepared pan.
8. Brush the loaf with a coat of egg wash (this keeps it from drying out) and cover with a piece of lightly oiled plastic wrap. Proof at room temperature until the dough is puffed and roughly doubled (if you’re using a pullman pan, the dough should fill the length of the pan and be about an inch from the top). This usually takes me ~8 hours, or overnight. Cover and refrigerate the egg wash; you’ll use it again later.
9. About 45 minutes before you’re ready to bake, preheat your oven to 400F with a rack in the middle. When the oven is preheated, gently brush the loaf with another coat of egg wash. Bake for 20 minutes, then turn the oven down to 350F, rotate the pan, and bake for another 20-30 minutes. (If the loaf is browning too quickly, tent a piece of tinfoil over the top.) When finished, the loaf should be well browned and register at least 195F in the center.
10. Gently remove the loaf from the pan and cool on its side (this helps the loaf retain its shape and keeps the bottom from getting soggy). Resist the urge to cut before the loaf has cooled; otherwise the texture will be gummy. Leftovers keep well at room temperature for a few days, well wrapped; it also makes excellent French toast.
