This is not a homework question, but I was just wondering, why can't a uniform electric field be described by the formula $$E=\frac{kq}{r^2}$$ ?

When we have to case of a uniform electric field, it means that the field is constant in a region of space. In the definition of the above electric field, what happens to the electric field as r increases and decreases.
