Why isn't sweet dough flaky?

Sweet dough isn't flaky because it typically contains a higher fat content and more sugar, which creates a tender, soft texture rather than a layered, flaky one. The fat in sweet dough is often mixed in thoroughly, resulting in a uniform structure rather than the distinct layers found in flaky doughs like puff pastry. Additionally, sweet dough usually includes eggs and other ingredients that contribute to its richness and moisture, further preventing flakiness.
