It's a digital representation of the digits from 1 to 9. Each dot represents the corresponding line in the traditional digital representation.

This can be clearly seen in the following image:

So the number 9 is represented by:

    $\begingroup$ @O.Rares the dots directly correspond to a seven-segment display, like what you'll find on many digital clocks. If you stretch the dots out so that they look more like those clocks' displays, it should be easier to spot the pattern. $\endgroup$

    $\begingroup$ This seems to make sense to be, besides what is supposed to be the "4". Unless its rotated... $\endgroup$

I see a pattern as a tool to make cookies

enter image description here

So we need to find a new cookie type.
At begin I saw there wasn't the one white dot and the white dot pattern in the center only.

As I looked closer at all patterns I can say that all can be rotated to change the black dots position in order to give a different perspective to the cookie lovers in order to sell them.

As I write this answer I see second pattern of first and second row are the same.That maybe,maybe not ,can confirm the rotation rule.

My guess is


I eliminated each time a black dot and created different patterns and compared with the existing one to get those
