Are chocolate chip cookies a compound?

* Compounds are formed when two or more elements chemically combine in a fixed ratio. For example, water (H₂O) is a compound because it's always made of two hydrogen atoms and one oxygen atom.

* Mixtures are combinations of substances that are not chemically bonded. They can be separated by physical means.

Chocolate chip cookies are made up of various ingredients like flour, sugar, butter, eggs, chocolate chips, etc. These ingredients retain their individual properties even when mixed together. You can separate the chocolate chips from the cookie dough, for instance. Therefore, a chocolate chip cookie is a mixture, not a compound.
