A great pain au chocolat is one of the most honest pleasures in baking. Two batons of dark chocolate wrapped inside dough that has been folded, chilled, and folded again until it holds hundreds of paper-thin layers — then baked until the outside shatters and the inside steams open, melting the chocolate into something approaching silk. This is that recipe.
It is not fast. Laminated dough demands two days and a certain willingness to trust the process during the moments it looks wrong. But the actual hands-on time is modest, and the result — warm from the oven, chocolate pooling in the center, layers pulling apart in ribbons — is the kind of thing that makes everyone in the kitchen stop what they're doing.
"Good lamination isn't magic. It's cold butter, a rested dough, and the discipline to not rush a single fold."
Why This One Works
The secret to a croissant with real structure and audible crunch is keeping the butter cold and distinct from the dough throughout every fold. When that butter hits the oven, it releases steam between each layer, puffing them apart into the honeycomb of open crumb that defines a proper croissant. Rush the process — let the butter soften too much, skip a rest, force the roll — and you get bread. Patient, and you get lamination.
For the chocolate, use a high-quality bittersweet bar at 60–70% cacao, cut into rectangular batons rather than chips. Chips are formulated to hold their shape — they won't melt the same way. Two batons per croissant gives you the right ratio: enough chocolate to pool and flavor every bite without overwhelming the pastry itself.
Before You Begin
Tip 01
Give yourself two days
The dough needs overnight cold fermentation after mixing, then resting time between folds. Build this into a Saturday–Sunday schedule and it flows naturally.
Tip 02
Use European-style butter
Higher butterfat (82–84%) means less water, which means crisper, more distinct layers. Plugrá, Kerrygold, or any cultured European butter are all excellent choices.
Tip 03
Temperature is everything
If at any point the butter feels soft or starts to seep through the dough, stop immediately. Wrap it and refrigerate for 20–30 minutes before continuing.
Tip 04
The egg wash is non-negotiable
Two coats of egg wash — one before proofing, one just before baking — gives you that deep mahogany glaze. Skip it and the croissants look pale and sad.
The fold. Each turn creates dozens more layers — the rhythm of the work is almost meditative once you find it.

Détrempe (Base Dough)
- 500g bread flour, plus more for dusting
- 10g fine sea salt
- 75g granulated sugar
- 7g instant yeast (1 packet)
- 300ml whole milk, cold
- 40g unsalted butter, softened
Beurrage (Butter Block)
- 280g European-style unsalted butter, cold (82%+ fat)
Filling & Finish
- 200g dark chocolate (60–70% cacao), cut into 24 batons
- 2 large eggs
- 2 tbsp whole milk
- 1 pinch flaky sea salt (optional, for finishing)
Instructions
-
1
Make the dough (Day 1). Combine flour, salt, sugar, and yeast in the bowl of a stand mixer fitted with a dough hook. Add the cold milk and softened butter. Mix on low for 2 minutes, then medium for 4–5 minutes until a smooth, slightly tacky dough forms. Do not over-develop the gluten — you want it just barely smooth. Shape into a rectangle, wrap tightly in plastic, and refrigerate overnight.
-
2
Prepare the butter block. Place the cold butter between two sheets of parchment. Using a rolling pin, pound and roll it into a 7-inch square of even thickness. It should be pliable but still cold — bendable without cracking. Refrigerate if it softens.
-
3
Enclose the butter (Day 2). On a lightly floured surface, roll the chilled dough into a 14×7-inch rectangle. Place the butter block in the center. Fold the dough over the butter from both sides, like an envelope, pinching all edges to seal. You now have a dough-encased butter packet.
-
4
First fold (letter fold). Roll the packet into a long rectangle, roughly 8×20 inches, working gently. Fold the bottom third up and the top third down over it, like a business letter. This is one turn. Wrap and refrigerate for 30 minutes.
-
5
Second and third folds. Repeat the rolling and letter-fold process two more times, refrigerating 30 minutes between each turn. After the third fold, wrap and refrigerate for at least 1 hour, or up to overnight.
-
6
Shape the croissants. Roll the laminated dough into a large rectangle, approximately 9×18 inches and about 4–5mm thick. Trim the edges neatly to expose the layers, then cut into 12 rectangles (each about 4.5×6 inches). Place two chocolate batons horizontally across the bottom edge of each rectangle. Roll the dough firmly over the chocolate and away from you, keeping tension as you go. Place seam-side down on parchment-lined baking sheets.
-
7
First egg wash and proof. Whisk together the eggs and milk. Brush each croissant lightly with egg wash. Loosely cover with plastic wrap and let proof at room temperature for 2–3 hours, until nearly doubled and jiggly when the pan is shaken gently.
-
8
Bake. Preheat the oven to 400°F (205°C). Apply a second thin coat of egg wash to the croissants, taking care not to let it drip down the cut sides (it will glue the layers together). Bake for 18–22 minutes until deep mahogany brown. Rotate the pan once halfway through. Finish with a pinch of flaky salt if desired. Cool on a wire rack for at least 10 minutes before eating — the chocolate inside needs a moment to set slightly.

There is a specific Sunday morning that this recipe is made for. Coffee already brewed, kitchen quiet, oven warming. You pull the tray out and the croissants are exactly the right color — a burnished, lacquered brown that looks almost too good to touch. Then you tear one open and the layers fall away from each other in ribbons, and the chocolate is exactly as melted and dark as it should be. That morning is worth every fold.
"The layers don't lie. You can taste every fold."
