4. Flat bread made from dough:[1]

All dough made from five grain flour which is baked, irrelevant of thinness, has the same status as baked bread and hence one is to recite Hamotzi on any amount of it that one consumes and recite Birchas Hamazon if he ate a Kezayis within Achilas Peras.

• Examples: For lunch, Yaakov bakes a traditional flatbread from regular dough. Since this is just like ordinary bread, before eating a piece the size of a Kezayis, Yaakov recites Hamotzi and, after eating, says Birchas Hamazon.
