Breton Kouign-Amann with Salted Butter & Caramelized Sugar

Directions

1. Mix the yeast dough

   Stir milk, yeast and 2 tablespoons sugar in a large bowl. Add bread flour, salt and melted butter; mix until shaggy, then knead 6 to 8 minutes until smooth. Shape into a square, cover and refrigerate 45 minutes.

2. Make the butter block

   Place the cold salted butter between parchment sheets and pound and roll it into a 6-inch square of even thickness. Chill until firm but bendable, about 15 minutes; it should flex without cracking.

3. Lock in the butter

   Roll dough into a 9-inch square with corners pointing north, south, east and west. Set the butter square in the center with its corners pointing toward the dough sides. Fold dough corners over it like an envelope and pinch every seam closed.

4. Complete the first fold

   On a lightly floured surface, roll the packet into an 8-by-20-inch rectangle. Brush away loose flour, fold the bottom third up and top third down like a letter. Wrap and chill 30 minutes.

5. Complete two more folds

   Turn the dough 90 degrees, roll again to 8 by 20 inches and letter-fold. Chill 30 minutes. Repeat one final roll and fold, then chill 45 minutes so the butter and dough firm evenly.

6. Sugar and shape

   Generously butter a standard 12-cup metal muffin pan. Scatter 1/4 cup sugar over the work surface, roll dough to a 12-by-16-inch rectangle and sprinkle with another 1/4 cup sugar. Cut twelve 4-inch squares. Bring each square's corners to the center and press lightly; place seam-side up in the cups.

7. Proof

   Sprinkle pastries with the remaining 1/4 cup sugar. Cover loosely and proof at cool room temperature for 35 to 50 minutes until visibly puffy but not doubled. If butter begins to melt, refrigerate the pan for 10 minutes.

8. Bake to deep gold

   Heat the oven to 400°F with a rack in the lower-middle position. Set the muffin pan on a rimmed sheet and bake 15 minutes; reduce to 375°F and bake 12 to 16 minutes more until deeply caramelized and 200–205°F in the bready centers.

9. Unmold while warm

   Cool exactly 3 to 5 minutes, then use a thin buttered spatula to lift each pastry onto a rack. Do not leave them in the pan: the caramel will harden and glue the pastries in place. Cool at least 20 minutes before eating.

Why this works

Swaps & notes

Easy swaps

• Use unsalted European-style butter for the block and add an extra 1/4 teaspoon fine salt to the dough.
• Bake in well-buttered 3-inch metal pastry rings on parchment for a straighter bakery shape, watching for caramel leakage.
• Bread flour gives the most support, but all-purpose flour works with slightly more delicate handling and may need 1 tablespoon less milk.

Cook notes

• Total time includes three substantial chilling periods, proofing, baking and cooling; active work is about 65 minutes.
• Use a metal muffin pan, not silicone, for strong caramelization and easier hot unmolding.
• If butter breaks through the dough, dust the spot lightly with flour, chill 20 minutes and continue gently rather than rolling harder.
• Hot caramel causes serious burns. Keep hands clear of pooled sugar and unmold with a utensil onto a heat-safe rack.

Storage

Kouign-amann are best the day they are baked. Store airtight at room temperature up to 2 days and re-crisp in a 325°F oven for 6 to 8 minutes. Freeze cooled pastries up to 1 month; thaw and reheat before serving.
