Bread, cake, cookies, crackers, and the like, all fall into the category of “Pat Akum,” bread of a Non-Jew, which is more lenient than the cooked food of a Non-Jew, “Bishul Akum.”
Bread of a Non-Jew, even though it is from only Kosher ingredients, is not permitted when baked by a private person, but is permitted from a restaurant, bakery, and of course packaged in a supermarket. These are termed “Pat Palter.”
