Kouign-amann

Kouign-amann is laminated dough folded with butter and sugar and baked until the outside caramelizes into a hard, sticky crust. It's Brittany's butter cake — the name is Breton for "butter cake," plainly — and it's a genuinely different pastry from a croissant, not just a sweeter version of one: the sugar folds directly into the dough's layers rather than being dusted on top afterward.

What it actually is

A yeasted wheat flour dough laminates with butter the same way croissant dough does, folded repeatedly to build up thin alternating layers. What sets it apart is that a generous layer of sugar folds in alongside the butter during those final folds, so the sugar sits baked into the dough itself rather than on its surface. As it bakes at high heat, that internal sugar caramelizes against the pan, turning the outside into a hard, deeply browned, faintly burnt-sugar crust while the inside stays soft and buttery in flaky layers.

The caramelized crust is the specific point of the dish, not a byproduct to avoid. A version pulled from the oven before that crust fully forms is under-baked kouign-amann, not a lighter version of it — the contrast between the hard, sticky outside and the soft layers within is what the pastry is built around.

How it's served

• Whole or cut into individual portions, warm or at room temperature.
• As a breakfast or snack pastry, alongside croissants and other viennoiserie.
• Without extra glaze or filling, since the caramelized sugar crust already carries the sweetness.

Writing it on a menu

• Flag gluten and dairy; the flour and butter lamination carry both.
• Say that it's not the same as a croissant, since the sugar folded into the layers and the caramelized crust make it a distinctly different pastry.
• Note that it's rich and quite sweet, more so than a plain croissant, given the sugar baked directly into the dough.
• Mention if it's made in individual portions or a larger cake cut to order, since both are traditional.
