What Is Pain Au Chocolat?
Pain Au Chocolat is a classic French pastry, not only sold in viennoiseries across France but also widely popular across the world. We have not yet stayed at a hotel that didn't have these flaky buttery pastries as an option at a breakfast buffet.
Pain au Chocolat is also known as Chocolatine in some parts of Europe, or simply as Chocolate Croissant. The latter, however, is up for debate. Croissant indicates the crescent shape of the pastry, and Pain Au Chocolate is typically shaped like a rolled rectangle. Whatever you'd like to call it, we invite you to try our dark chocolate filled pastries made with a sourdough starter! They are absolutely scrumptious!

Note on the Choice of Ingredients
- strong bread flour: strong bread flour has a higher gluten content, which translates into a better rise, and higher water absorption, making the dough easier to roll and better moisture retention, making the inside of Pain au Chocolat flaky but not dry.
- sugar: we prefer using caster sugar over granulated sugar because caster sugar is finer and dissolves in the dough quicker.
- butter: use unsalted European-style butter, as it has higher fat content compared to American butter.
- chocolate: whilst it is convenient to use chocolate buttons for pain au chocolat, they are not always easy to find in supermarkets. We, therefore, opted for a 150g bar of dark chocolate. We particularly recommend baking chocolate that crumbles less when cutting and doesn't fully solidify inside the pain au chocolat after baking and cooling. The one we used was 45% cocoa dark chocolate.
Step 1: Before You Start: Tips for Sourdough Starter
Sourdough Pain au Chocolat are naturally leavened and doesn't rely on commercial yeast for the rise of the pastry. As a result, it is critical that you use a strong active sourdough starter. And this goes for any enriched dough, including Sourdough Ham & Cheese Croissants, Kouign Amann, Sourdough Cruffins, Sourdough Pain Aux Raisins or Plain Croissants.
Here are a few tips:
A sourdough starter that is low in acid will work best. That simply means that your starter needs to be frequently refreshed prior to using it to make the laminated pastry. Détrempé (the dough) for pain au chocolat is enriched with milk, butter and sugar and will require that little extra might of the natural yeast to rise the dough. We recommend you feed a little bit of your starter for 2-3 days in a row before using it for Sourdough Pain au Chocolat. Regular feeds will ensure both low acidity and strong yeast.
Another important thing to remember is that sourdough starter is best when used at its peak (and never once it starts to deflate unless the recipe specifies 'sourdough discard'). Once you fed your starter one last time before making pain au chocolat, leave it in a warm spot for 4-5 hours. It should double (maybe even triple in volume) in that time and you're fine to use it then. If you leave it for longer, your starter may reach its peak and then start deflating. If your starter hasn't doubled in 4-5 hours at 20-24°C, you may need to keep feeding it for a couple more days before it's fit for purpose (and there's only one purpose - to get our teeth on those great Sourdough Pain au Chocolat, right?).
Step 2: Making Détrempé
Once your starter is at its peak, make the détrempé (the enriched dough that is one of the 3 main elements of pain au chocolate - détrempé, butter lamination and chocolate filling).
In a bowl of your stand mixer (we absolutely love our Kenwood), fitted with a dough hook attachment, mix the strong flour, salt and sugar. Pour in the water, milk and active sourdough starter. Turn the stand mixer on and knead for 5 minutes at medium speed. The dough will come together into a rather stiff ball (don't expect it to look smooth or elastic at this stage, it may even look a bit dry). Leave the dough to relax for 15 minutes.
Run the stand mixer again on medium speed, and start adding 50g of room temperature butter a little bit at a time. Make sure your butter is soft (hard butter will have trouble combining with the dough). Keep the mixer running for around 8-10 minutes until the butter is fully incorporated and you have a smooth dough. It shouldn't be sticky.
Shape a tight ball, and slash the dough with a sharp knife (a razor or a dough scorer) in a cross on top of the dough (see photo below). This will help you roll the dough out into a square/ rectangle rather than a circle. Place the dough in a lightly greased bowl. Cover and leave in a warm spot to bulk prove for approx. 4 hours. Ideally, you need a temperature of 21-23° C. If it is warmer, adjust the timing: your dough should rise x1.5 times. Place the dough in the fridge for another 3-4 hours to finish proving and double in size. Finishing with a cold-proof helps roll the dough out later as it will be nice and firm.
Step 3: Laminating
Laminated pastry creates that flaky effect that good croissants and pain au chocolate are known for. This is achieved by creating thin layers of détrempé and butter. The butter is encased in the dough and then rolled out, folded and rolled out twice more.
Prepare the Butter
Take the butter out of the fridge in advance so it is soft enough to be rolled. Place it on a large sheet of baking parchment (we highly recommend Bacofoil Baking Parchment - it is strong and lasts forever), place another sheet of parchment on top. Using a rolling pin, gently bash to flatter the butter. Then fold the baking parchment under into a neat 18x18cm (7×7 in) square and roll the butter inside the parchment parcel into all four edges, aiming for the same thickness across (for process photos see below). Enclosing the butter into the baking parchment square will help you get an even butter square with sharp edges. Still wrapped in the baking parchment, place the butter in the fridge to firm up.
Butter Temperature for Laminating Process
An important element of making the flakiest of pain au chocolat is ensuring the butter doesn't melt into the détrempé dough in the lamination process. In order to achieve this, you need your butter and dough of similar temperatures (or the dough slightly colder). What is more, you don't want the butter too cold either, otherwise, it will brittle instead of creating even layers when you try to roll the pastry. Judging the temperature of the dough and the butter will come with practice, but if the butter is too hard, just leave it out to soften.
The pastry should also be chilled in the fridge between folds to ensure the butter stays cold and doesn't melt into the dough.
Lamination
Take the dough out of the fridge and place it onto a floured worktop. Knock the air out with the bottom of your palm and roll it into a square around 28x28cm (11x11in). Try to make it even.
Unwrap the butter (keep the baking parchment). Place the butter in the middle of the dough on the diagonal (see the photos below).
Taking one side at a time, fold the edges of the dough into the middle creating a square envelope. Once you fold all four sides into the middle, pinch the edges together. You should now have a 20x20cm (8x8in) butter parcel. Wrap it in baking parchment and freeze on a flat surface for 10 minutes.
First Fold
Take the parcel out of the freezer, unwrap and roll the parcel out into a rectangle that's around 50x20cm (20x8in). Make sure your dough isn't sticking to the worktop as you roll: you want the butter encased and the dough may tear if it sticks. Dust with flour if needed. Using a sharp knife or a pizza cutter, cut off any untidy short edges that don't have any butter in them.
Fold the rolled-out dough like a letter: from the short edge, hold ⅓ of the sheet into the middle, then take the opposite short edge and fold it over the first one. Wrap the dough in the baking parchment you kept the butter in, or cling film, and place in the freezer for 15 minutes, then transfer to the fridge for 1 hour.
Second Fold
Take the dough out of the fridge and place it short edge in front of you. Roll the dough out to 50x20cm (20x8in) again. Fold the top third towards the centre and then the bottom third over (just like before). Wrap and place the pastry in the freezer for 15 minutes, then fridge for 1 hour.
Third Fold
Just like before, roll out the dough to 50x20cm (20x8in) rectangle. Fold like a letter, wrap and place in the fridge for a minimum of 6 hours (we leave it in the fridge overnight).
Step 4: Shaping Pain Au Chocolat
Take the pastry out of the refrigerator and let it warm up for 5 minutes at room temperature. Unwrap and, on a lightly floured worktop, roll the pastry out into a 60x40cm (24x16 in) rectangle, gently getting all the air out of the pastry. You don't want pockets of air to burst abruptly though, exposing the butter.
Trim the pastry from all four sides to create even edges. Using a sharp knife or a pizza cutter, cut the pastry sheet in half lengthways. Then each long strip into 6 rectangles measuring 20x10cm (8x4in). You should have 12 even rectangles (see photos below).
Boil a kettle of water. Pour the water into an ovenproof dish and place it in the bottom of your cold oven. Close the oven door and let the water steam inside.
Line two large baking sheets with baking parchment.
Taking one rectangle at a time, place a line of chocolate along the short side, about 2-3cm away from the edge. Fold the pastry over the chocolate. Then add another line of chocolate next to the fold. Continue to roll until you have a neat spiral. Repeat with the rest of the rectangles. Place the sourdough pain au chocolat seam side down on the prepared baking sheets spaced out, leaving enough space for them to rise.
Step 5: Proving Shaped Pastries
Importance of Temperature and Humidity
Your oven should be warm and humid by now. The optimal temperature should be around 23-24 C (any higher and your butter will start melting into the pastry). The humid environment will ensure that the pain au chocolat won't form a crust on top, preventing the pastries from rising. I like to cover them with a large sheet of lightly oiled clingfilm too.
Place the sheets with sourdough pain au chocolat in the turned-off oven for 3-4 hours to prove. The pastries should puff up significantly and the layers should be clearly visible.
STEP 5: Egg Wash
Once your pains au chocolat have proved, we like to place them in the fridge for 15-20 minutes. the pastries will firm up and won't be as fragile when you are brushing them with egg wash. Furthermore, the butter in them will have time to solidify a bit again to help create perfect flaky layers.
Whilst the sourdough pain au chocolat are chilling, take the ovenproof dish with water out of the oven and then preheat it to 190°C Fan.
In a small bowl, whisk the egg yolk and cream (or milk). Using a pastry brush, very gently brush the pastries with the mixture.
STEP 6: Baking Pain Au Chocolat
Bake the pastries for around 20-25 minutes. Leave the sourdough pain au chocolat to cool for 30 minutes. They are best served within 2 hours from baking! We enjoy them most when they are still warm and the chocolate is oozing out!
Recipe FAQs
Whilst these French pastries are best served on the day of baking (within 2 hours preferably), they can be stored in airtight containers at room temperature for 3 days.
Yes! Preheat the oven to 180 C and place the pastries on the middle shelf for 4-5 minutes.
The best way to freeze Pain Au Chocolat is before they are baked. Once the pastries are shaped and proved (but before egg washing) place them in the freezer (still on a baking tray) for 1-2 hours. Once they are frozen, transfer them into a ziplock bag and keep them in the freezer. You can then cook them from frozen for about 25-30 minutes.

Thanks, Kushigalu! 💗
April says
How adorable are these! Thank you for the very detailed instructions, confident they'll turn out well. Can't wait!
Ieva says
I'm sure they will! Let me know if you have any questions - I'm here to help! 💗
HB says
All went well until the boling water and oven proof! Butter leaked from the croissants all over the pans and all over the oven. So I have smoke pouring out of my oven right now from the burnt butter. Next time definitely let them proof on counter. Even if they still come out they’ll taste nice and smoky I’m sure. Not awesome!
Ieva says
Sorry to hear the butter has leaked out for you! Maybe the temperature was too high in the oven when you placed your pain au chocolat in it? As per the recipe, we recommend that it's no higher than 24 C for the second proof. Hope they did not taste too smokey and there was enough butter left to create flaky layers.
Mahy says
Oh wow - these would be so good in the morning with a cup of hot tea or coffee... Delicious!
Angelica says
Hi there,
what is the oven temperature for the final baking, still 190 degrees with fan?
Thanks
Ieva says
Yes, 190 C fan. If your oven runs a bit hot, we suggest baking the on the lower shelf 🙂

Thank you so much! I always said that sourdough is so much easier to work with when it comes to laminated pastry! So glad you gave this recipe a go! 😀
Sonja says
These Sourdough Pain au Chocolat were such a satisfying weekend project! I loved the detailed instructions and the taste...I mean, nothing beats sourdough in baked goods, does it? Only problem: Now I don't want the storebought ones anymore.
Ieva Greber says
It's a great problem to have - homemade is (almost) always better! Thank you for such a lovely comment 🙂
Criss says
These sourdough pain au chocolat are next-level delicious! I tried the recipe, and the flaky, buttery layers with the rich chocolate filling were perfection. They take a little time, but the result is so worth it. Perfect for a weekend baking project—highly recommend giving them a try!
Ieva Greber says
Thank you so much, Criss! So so pleased you liked the recipe and found the extra time worth it! 💗
Shelley says
These might be the best thing I’ve made in years! Amazing. Can you freeze them?
Ieva Greber says
Thank you so much! Absolutely, you can freeze them. I tend to freeze them after baking, wrapped individually in plastic wrap (cling film) in a freezer-friendly bag. Thaw and reheat for 3-4 minutes, and they taste almost freshly baked! 🙂
Julie says
Great instructions! First go-round I had both my AP and bread flour out and realized I used the wrong one. Also thought I'd be smart and turn the oven light on for just a little warmth in proofing and that was a mistake. Some butter leaked. They still turned out great though, with plenty of layers. Second time I'm using the bread flour and no light and there is no butter leaking and they look beautiful! Can't wait to bake them and have the even better version. Lessons learned - use the strong flour and even just the oven light produces too much warmth.
Ieva Greber says
Oh I love this, thank you for sharing! Such a good reminder that pastry dough really does like to keep us humble. So glad the second batch is looking beautiful! 🙂
