Potato chip cookies are traditional American cookies that are especially popular in New England and the mid-Atlantic. The cookies are usually made with a combination of crushed potato chips, flour, butter, sugar, salt, egg yolks, and vanilla extract.
Butter, sugar, egg yolks, and vanilla are beaten until fluffy, and then mixed with flour, potato chips, and salt. The dough is rolled into balls that are flattened with the bottom of a drinking glass. The cookies are baked until lightly browned on the bottom, then cooled and served.
