Is a chocolate chip cookie heterogenous mixture?

A heterogenous mixture is a mixture in which the components are not uniformly distributed throughout the mixture. This means that different parts of the mixture may have different compositions. For example, a salad is a heterogenous mixture because the different vegetables and dressing are not evenly distributed throughout the salad.

A chocolate chip cookie, on the other hand, is a homogenous mixture. This means that the chocolate chips are evenly distributed throughout the cookie dough, so that every bite of cookie will have about the same amount of chocolate chips.
