Is short bread a kind of cake or biscuit?

Here's why:

* Biscuit is a broader term encompassing baked goods that are typically unleavened or lightly leavened, firm, and often crisp.

* Cake is a baked good that is typically leavened with baking powder or baking soda, has a soft and spongy texture, and often contains frosting or other decorations.

While shortbread can be quite rich and buttery, it's generally not considered a cake because it lacks the leavening agents and soft, spongy texture that cakes are known for.
