The most likely do NOT serve PB cookies--the fat content is too hight!. . .
Our kitchen used to bake pre-formed frozen choc chip cookies. When the food changes came in (remember Michelle Obama?), we had to stop selling them and had to wait nearly a year for the cookie to re-formulated to comply with dietary requirements.
The new ones tasted fine, just like the old ones, gooey in the center when not overcooked. You know what they did to make them com? They made them smaller and somewhat thinner!
