Sourdough Brioche Babka with Toblerone and Caramelized White Chocolate

20 Jan

Sourdough Babka with Caramelized White ChocolateSometimes I swear that Jenni and Shelley, the ladies behind Sourdough Surprises, are inside my head, reading my thoughts. I was just contemplating baking all my leftover Christmas chocolate into brioche buns when they announced that January’s Sourdough Surprises recipe was going to be just that: sourdough brioche swirled with chocolate and topped with struesel, also known as babka.

There were no recipes specifically for a sourdough version, so I used a sourdough brioche recipe from Sourdough Companion with Smitten Kitchen’s non-sourdough babka recipe as a guide. For the first time, my usually-mild mannered sourdough starter really showed its personality and the resulting brioche had a pronounced sourdough tang to it. I’m not totally sure how I feel about a strong sourdough flavour in such a sweet application – it might be why there are so few sourdough brioche recipes out there – but aside from that it did make a pretty wonderful brioche: rich and buttery with a light, pull-apart, lacy texture.

To achieve that texture, you need to develop the gluten fairly well through lots of kneading, which can be kind of challenging with such a soft, wet dough. I used a “slap and fold” kneading technique which basically consists of scooping up the dough, whacking it down on the counter, and stretching and folding it over on itself, over and over again. Amazingly, it transforms a sticky mess into a smooth, cohesive, and elastic dough. Watch a video of the technique here and then try it yourself – it’s pretty satisfying. ;)

I filled one babka loaf with a chopped up Toblerone bar and the second with caramelized white chocolate, made out of all the leftover white chocolate from those ill-fated chocolate curls. Caramelized white chocolate, if you’ve never heard of it, is pretty amazing – it tastes like a cross between white chocolate and toffee and is as easy to make as melting white chocolate in the oven and giving it a stir every so often.

Both babkas turned out pretty decadent, even with the modest 100 grams of chocolate in each (Smitten Kitchen’s babka had about double that amount). Not exactly appropriate for a January detox after a chocolate-filled December, but I certainly wasn’t complaining. ;) Visit Sourdough Surprises to see some other mouthwatering babka!

Sourdough Brioche Babka

Sourdough brioche recipe adapted from Sourdough Companion, method from Bon Appetit. Babka technique from Smitten Kitchen and Purple Foodie. Be warned that brioche dough takes quite a long time to make – it needs several hours of rising time (mine took 5 hours) plus chilling time (several hours or overnight), so give yourself at least 2 days to get this done. Makes 2 large loaves.

Sourdough Brioche Dough

In a mixer bowl, combine:

250 grams 100% hydration starter

200 grams warm milk

Mix gently with a spatula until the starter is dissolved. Add:

500 grams all purpose flour

8 grams salt

With the paddle attachment, mix on low speed for 1 – 2 minutes until the dough comes together in shaggy lumps.

One at a time, stir in:

3 eggs

Stir well after each, then slowly pour in:

30 grams granulated white sugar

Increase the speed to medium and beat the dough until it is smooth, about 3 minutes. You might need to scrape it down off the paddle a few times.

At low speed, add in very small increments:

300 grams softened unsalted butter

You will probably have to scrape the dough off the paddle several times. Once all the butter is added, scrape the dough out onto an unfloured surface and perform the “slap and fold” technique until the dough turns from a wet, sticky mess into an elastic, cohesive, smooth dough that cleans the surface you are working on (sorry, no pictures – it required both hands and was waaay too messy to pick up the camera!). This took about 8 – 10 minutes for me.

Gather it into a ball and place it in a buttered bowl. Cover with plastic and put in a very warm spot to rise until double. I turned my oven into a proofing box by turning on the lowest setting for about 2 minutes to warm it up just a bit, then turning it off and putting the dough in it with just the light on. Five hours later it was risen.

Chill the dough for several hours or overnight, until hard all the way through.

Meanwhile, prepare the chocolate filling.

Chocolate Filling

Place in the bowl of a food processor:

200 grams chopped chocolate, leftover from Christmas or otherwise ;)

4 tbsp unsalted butter

a big pinch of flaky sea salt (for milk and white chocolate fillings especially)

(I made two half batches of filling, one with a 100 grams of milk chocolate Toblerone and the other with 100 grams of caramelized white chocolate – recipe below.)

Pulse until the chocolate is in small bits and you have a spreadable chocolate-butter mixture.

Babka Assembly

Butter two 9″ x 5″ loaf pans and line them with parchment paper. Set aside.

Gently turn the dough out onto a floured surface and divide it in half. Roll/pat one half into a rectangle about 8″ x 16″ and spread it with half the chocolate-butter mixture. Do this carefully so the dough doesn’t tear. Roll the dough up from one short end into a tight spiral.

With a big knife, cut the spiral lengthwise down the middle. Cross the two halves in the middle, cut sides up, then twist them over themselves from the middle out towards each end, making sure to keep the cut sides facing up. Place the twist in the prepared loaf pan. Repeat with the second half of the dough.

Cover lightly with plastic and let proof until expanded to touch the sides of the pan, probably an hour or two at room temperature. Or, you can let it proof for about an hour at room temperature, chill it overnight, then bring it back to room temperature in the morning and let it finish proofing (it might take quite a while for the dough to wake up after being chilled).

While the babka proof, preheat the oven to 350˚F and make the struesel topping.

Struesel Topping

In a bowl, mix together:

1 scant cup icing sugar

3/4 cup all purpose flour

a pinch of salt

Add:

1/3 cup softened unsalted butter

Work in the butter with your fingertips until until crumbly, then press the crumbs together to create large clumps of struesel.

When the babka are proofed, brush them with an egg wash (1 egg + 1 tbsp cream or milk), then sprinkle them very generously with the struesel.

Bake in the preheated 350˚F oven for about 55 minutes, then reduce the heat to 325˚F and bake for 15 – 20 minutes, until deeply golden brown. Let cool in the pans on a rack, then remove from the pans to slice and serve. Store in an airtight container for up to a few days (if it lasts that long!).

Caramelized White Chocolate

Adapted from David Lebovitz

Spread your chopped white chocolate (I used 100 grams to fill one babka) over the bottom of a baking dish. Place it in a preheated 250˚F oven for 10 minutes, then stir with a spatula, spreading the chocolate evenly over the bottom of the baking dish. Repeat, heating the chocolate and stirring at 10 minute intervals, until it starts to brown and caramelize and turns the colour of natural peanut butter (about 30 – 60 minutes). It may clump up and look chunky, but it will smooth out eventually (you can add a little bit of cocoa butter or vegetable oil to help smooth it out if you are concerned). Stir in a pinch of flaky sea salt and pour the caramelized white chocolate into parchment paper and chill to set. Can be stored and used like regular white chocolate.

    HELP: what is hydration starter in plain english?? (lol) Bit more researched on my part but I think my Mom used to bake this – babka is a polish word, or not?

    • Korena in the Kitchen January 20, 2013 at 8:36 am #

      The hydration of a starter refers to the amount of water in it, expressed as a percentage of the amount of flour, ie: this starter has equal amounts flour and water, therefore the water is equal to 100% of the flour… does that make sense? It’s the whole baker’s percentage thing, where every ingredient is expressed as a percentage of the amount of flour, which is always 100%. Makes it easy to scale recipes up and down. http://en.wikipedia.org/wiki/Baker_percentage

      I’m not sure if babka is specifically a Polish word – I think lots of Eastern European cultures make variations of babka…?

    • Babka Zosia March 28, 2013 at 5:57 am #

      babka means old lady or grandma in polish- traditionally babka is baked in bundt form which resembles old style (grandma’s) skirt.

  2. wendyjv January 20, 2013 at 8:30 am #

    Looks fantastic, as usual! :)

  3. Barbara Bamber | justasmidgen January 20, 2013 at 9:21 am #

    You have really outdone yourself with this one, Korena! Tobelerone is a huge favorite at Christmas in my house. I’d make this one this morning, except the kids have hidden their bars from me, lol! What a great idea.. and white chocolate as well, this must have smelled incredible when it was baking! xx

  4. Jenni (@GingeredWhisk) January 20, 2013 at 9:30 am #

    OH WOW! Korena! I am always really excited to see what you make, and you continue to astonish me. Your filling choices are utterly amazing and your babka look utterly perfect!! The dough was very wet, but the slap and fold method works really well here!
    Great minds think alike! :)

    • Korena in the Kitchen January 20, 2013 at 10:06 am #

      Thanks Jenni! Yeah, I loved discovering that technique for working wet dough – I am looking forward to using it lots more :)

  5. Robyn January 20, 2013 at 10:24 am #

    This is perfect! Thanks for the step by step instructions!

  6. Shelley C January 20, 2013 at 10:56 am #

    Wow – your babkas are SO amazing – they look SO delicious. I have no idea how I have never heard of caramelized white chocolate before, but now I won’t be able to stop thinking about it until I try it for myself! And I LOVE the slap and fold method for kneading high-hydration doughs – it’s so satisfying! :) I am so glateld you joined in this month, because I can’t imagine not having seen these absolutely outstanding babkas. YUM!!!

  7. Rebecca January 20, 2013 at 11:07 am #

    Your babkas are amazing! The caramelized white chocolate really intrigues me, I’ll have to try that sometime.

  8. jojo54 January 20, 2013 at 11:07 am #

    Both kinds of chocolate sound wonderful, although it is a wonder that you had enough to use as filling. I would be tempted to snack on them while baking and not have enough to bake with (chocolate is my downfall) ;)

    • Korena in the Kitchen January 20, 2013 at 1:09 pm #

      It was hard to stop myself from sneaking bits of chocolate, but I knew it was for the greater good of babka! ;)

  9. Amanda Embry January 20, 2013 at 12:22 pm #

    Toblerone babka – yum! I have a pretty mild starter, and even with the 15 hours of overnight fermentation, my babka didn’t have any sourdough tang, which I was happy with. Usually I kind of wish my starter had more kick, though.

    • Korena in the Kitchen January 20, 2013 at 1:11 pm #

      I wonder if the tang has to do with the feeding schedule – I keep my starter in the fridge and only feed it to build it up for baking with… I know that to make sourdough panettone, you are supposed to feed the starter every 4 hours to get rid of the sourness, which I might try the next time I decide to make sourdough brioche.

    You had me at Toblerone Korena :) mmmmmmm

  11. Sibella at bakingwithsibella.com January 20, 2013 at 3:13 pm #

    Korena, your babkas look like you have been making them for years and I love the fillings! Also learned something new about white chocolate, which I will be trying soon. I have to say again: You inspire me! XO

  12. narf77 January 20, 2013 at 6:59 pm #

    I died and went to heaven didn’t I?! Surely I did…where there are caramelised white chocolate roads and toblerone fountains and babka hedges and no-one needs to worry about calories or dentists or anything as mundane as that…babka heaven ala Korena…:)

  13. Jane @ The Wayward Oven January 20, 2013 at 7:58 pm #

    Toblerone? Droooool. Lovely. I think your babka has the most butter of any recipe I’ve read. No doubt, it would be delicious! And that caramelised chocolate? I think I’m in love. It’ll be my next project. Great job Korena!

  14. chef mimi January 21, 2013 at 6:28 am #

    Wow, the Toblerone was a genius flavor idea! Both are beautiful, the texture looks just perfect!

  17. The Little Spork January 22, 2013 at 5:41 pm #

    gah I can’t get over how good this looks! I’ve been eyeing Deb’s chocolate babka recipe for a while now, but I love your version of it!

  19. Lisa January 23, 2013 at 11:25 pm #

    You used Toblerone – I heart you! It’s just my favorite splurge chocolate in the whole world, white and milk. Not to mention, I LOVE caramelized white chocolate..I’ve been wanting to try it since I saw David Lebovitz’s post about it. Your babka is literally dreamy, Korena!

    • Korena in the Kitchen January 24, 2013 at 11:54 am #

      Thanks Lisa :) Caramelized white chocolate – you MUST try it, it’s amazing!

  20. Helena / Rico sin Azúcar February 3, 2013 at 9:56 am #

    Thanks for the “slaps and fold” video! the dough looks soft and elastic, just like gum ;-) Wonderful streusel topping!

  21. My Italian Smörgåsbord February 22, 2013 at 7:28 am #

    finally I found some time to comment on this one: A.M.A.Z.I.N.G.
    possibly one of the fluffiest sweet sourdoughs ever seen. And what a creative idea to have toblerone in it! I am totally captivated by the method and this is totally on my to do list, just so you know.
    ciao, Barbara

    This looks insanely delicious! Toblerone is really fantastic to bake with – it gets so wonderfully caramel-y… We recently tried it with some cookies (http://goldendreamland.blogspot.com/2014/01/recipe-toblerone-cookies.html) to great result.
