I’d never heard of a Sablé cookie before Animal Crossing (by the way, it’s a French word that’s pronounced “sah-blay”). But kind of randomly on a trip to Taiwan, I came across some Sablé cookies in the shape of Miffy the bunny from Japan. They were so delicious (and they don’t sell them anymore) that I resolved that one day, I would attempt to make my own.
Sablé cookies are also known as “Breton” or “French Butter” cookies. They originated in the town of Sablé-sur-Sarthe in northwestern France around 1670. The word “Sablé” means “sandy”, but don’t let that put you off, as it’s just referring to the texture of the dough, which feels like shortbread dough. The main difference is that in addition to the massive amounts of butter that are in traditional shortbread dough, the French add egg yolks. The result is a delightfully crispy and buttery cookie. They’re as popular in France as chocolate chip cookies are in the US.
An Italian in My Kitchen has one of the best recipes for these cookies. It's a simple recipe that includes butter, sugar, egg yolks, flour, and vanilla. Just follow the recipe to make the dough and then roll it out, not too thick, not too thin.
