How do we use the word 'goodness' correctly?

[Eagle]

Hello.

I have a question about this use of goodness:

On a box of cookies, the slogan says: Simply goodness.

What does mean in that expression.

Thanks in advance

You must in general beware of the supposed grammar of advertising slogans. I would have to have a sample cookie to be sure, but this slogan likely means that these cookies contain simple and delicious ingredients and are 100% good, and there is nothing more to be said about them.
