Authentic Breton Kouign-Amann
An expert-level guide to the pride of Brittany, France. This intricately laminated pastry features alternating layers of yeast dough, premium salted butter, and sugar that yields a shattering, deeply caramelized crust and a tender, buttery interior. Mastering the butter temperature and sugar incorporation is key to preventing weeping and achieving the perfect caramelization.
Equipment
- Stand mixer with dough hook
- French rolling pin
- Ruler
- Bench scraper
- Parchment paper
- 12 pastry rings (3-inch) or a jumbo muffin tin
- Digital instant-read thermometer
Ingredients
Détrempe (Dough)
- 3 cups Bread flour — Around 360g. Higher protein helps support the heavy butter and sugar structure.
- 1 cup Water — Warm (90°F/32°C)
- 2.25 teaspoons Active dry yeast — 1 standard packet (7g)
- 1 teaspoon Kosher salt — Diamond Crystal. Halve if using table salt.
- 1 tablespoon Unsalted butter — Melted and slightly cooled
Beurrage (Butter Block)
- 1 pound European-style salted butter — Must be 82% fat or higher (e.g., Kerrygold, Isigny Ste-Mère). Cold.
Tourage & Coating (Sugar Layers)
- 1.5 cups Granulated sugar — Divided use for the final turns and shaping
- 0.5 teaspoons Fleur de sel — Mixed into the sugar for a traditional Breton flavor profile
- 2 tablespoons Unsalted butter — Softened, for greasing the molds

Instructions
-
Mix the détrempe: Dissolve the yeast in warm water and let sit for 5 minutes. In a stand mixer fitted with a dough hook, combine the flour, salt, melted butter, and yeast mixture. Mix on low speed for 3-4 minutes until a rough dough forms. It should not be overly developed or elastic yet.
~10 minMinimal gluten development here makes the dough easier to roll during lamination. -
Shape and chill the détrempe: Turn the dough onto a lightly floured surface, shape it into a rough 6x6-inch square, wrap tightly in plastic wrap, and refrigerate for 1 hour to relax the gluten and chill the dough.
~60 min -
Prepare the beurrage: Place the cold butter sticks between two sheets of parchment paper. Pound with a rolling pin to soften, then roll into an even 6x6-inch square. The butter must be pliable but cold (around 60°F/15°C). If it gets too warm, chill it briefly.
~10 minTemperature matching between dough and butter is critical. Both should bend without breaking or melting. -
Lock in the butter: Roll the chilled détrempe out to an 8x12-inch rectangle. Place the butter square in the center. Fold the top and bottom thirds of the dough over the butter to encase it completely. Pinch the seams horizontally to seal.
~5 min -
First Turn (Single Fold): Rotate the dough 90 degrees so the seam is vertical. Roll the dough out to an 8x18-inch rectangle. Fold into thirds like a letter. This is your first turn. Wrap and chill for 45 minutes.
~45 minAlways roll straight away from your body; do not roll the pin off the edges of the dough to maintain even thickness. -
Second Turn: Repeat the rolling and folding process (8x18 rectangle, fold in thirds). Wrap and chill for another 45 minutes.
~45 min -
Prepare the molds: Generously brush the inside of your pastry rings (set on a parchment-lined baking sheet) or a jumbo muffin tin with softened butter. Coat the buttered molds with a layer of granulated sugar.
~10 min -
Third Turn (Sugar Turn): Mix the 1.5 cups sugar with the fleur de sel. Sprinkle 1/2 cup of this mixture onto your work surface. Place the dough on the sugar, sprinkle another 1/2 cup on top. Roll the dough out to an 8x18-inch rectangle, pressing the sugar into the dough. Fold in thirds, incorporating the sugar inside. Chill for 30 minutes.
~30 minDo not chill longer than 30 minutes after adding sugar, or it will begin to draw out moisture and weep. -
Final rollout and shaping: Sprinkle the remaining sugar on the counter. Roll the dough out to a 12x16-inch rectangle. Trim the edges to make them straight. Cut the dough into twelve 4x4-inch squares. For each square, fold the four corners into the center (like a windmill or envelope), and press lightly to adhere. Place each shaped pastry into the prepared molds.
~15 min -
Proofing: Cover lightly with a towel and let rise at room temperature for 30-40 minutes until slightly puffy. Do not proof in a warm place, or the butter will leak out.
~40 minIdeal proofing temperature is 68°F-72°F (20°C-22°C). -
Baking: Preheat oven to 400°F (200°C). Place the pastries in the oven and immediately reduce the heat to 375°F (190°C). Bake for 22-26 minutes until the tops are deep golden brown and the edges are dark caramelized sugar.
~25 minKeep a close eye during the last 5 minutes. The sugar can go from perfectly caramelized to burnt very quickly. -
Unmolding: This is crucial. Immediately upon removing from the oven, use tongs or a fork to lift the Kouign-Amann out of the molds onto a wire rack. If you let them cool in the pan, the caramel will harden and cement them to the pan.
~5 minWork quickly and carefully—the molten caramel is extremely hot.
Tips & Storage
- Butter temperature is the single most important factor. If butter is too cold, it will shatter inside the dough. If too warm, it will absorb into the dough. Keep it pliable.
- Do not add the sugar to the dough until the final turn. Sugar acts as a tenderizer and draws out moisture; adding it too early destroys the lamination.
- If your kitchen is very warm, chill the rolling pin and marble slab/countertop before rolling.
- Storage: Kouign-Amann are best eaten the day they are made. Leftovers can be stored in an airtight container at room temperature for up to 2 days. Reheat in a 350°F (175°C) oven for 5 minutes to recrisp the caramel.
