About Gâteau Breton
Gâteau Breton is a traditional butter cake associated with Lorient and Port-Louis in Brittany. This profile follows the plain four-ingredient version made from wheat flour, semi-salted butter, sugar and egg yolks.
Semi-salted butter dominates the flavour, giving the cake a rich dairy character sharpened by a gentle savoury edge. Sugar supplies a clean sweetness, while egg yolks add depth without extra flavourings or fillings.
The cake is round, thick and deeply golden, with a fork-scored crosshatch across its firm top. Inside it is dense, tender and crumbly like a rich shortbread cake rather than light or aerated sponge.
