I think it should be:

Do you keep making it?

and

Are you still making it?

I hope this could help. :)

I'm not really sure how to explain it, but I will do my best😊. I will explain the comment by Jose, where the sentences are "Do you keep making it?" and "Are you still making it?"

"Do you keep making it?" is a question that means to ask if you make something regularly or always. It results due to frequency. For example, an employee at a cafe breaks a glass. She was forgiven for her mistake, but she kept on making the same mistake over and over again in that day. It means that she keeps on doing it.

"Are you still making it?" is a question that asks if you are still making something that you did a while ago. For example, a mother is cooking something and her daughter asks what she was making. The mother answered that she was making pancakes. After asking the girl went upstairs to play. After 15 minutes the girl went to her mother again and saw that her mother is not finished cooking. That's when she asks "Are you still making it?"

Basically it all falls down to "still" and "keep". "Still" is limited by the time of the doer of the verb. On the otherhand, "Keep" is not limited ti time since it is related to frequency.  Please correct me if I'm wrong😅

I agree with most of the other comments.  The root of the confusion can be from the various definitions of "to keep"--to have/retain possession (to keep all of your money) and to continue a condition/position/action (to keep/continue to argue; to keep/continue waving a flag; to keep/to continue to have your door open). 

1)  If you want help to determine if your usage is correct for retaining possession, try replacing "keep" with "maintain possession of " or "retain".  For example, Why are you (KEEPING/RETAINING/MAINTAINING POSSESSION OF) that old car?

1) When you are trying to determine if your usage is correct for continuing a condition/position, try to replace "keep" with "continue".  For example,  "Why do you KEEP/CONTINUE making cookies/errors/music videos"; "You KEEP/CONTINUE driving quickly".  When referring to continuing a position/status (to keep your store open or your mouth closed), you have to make some other changes when you use CONTINUE (e.g. To KEEP your store open becomes To CONTINUE TO HAVE/MAINTAIN your store open; to KEEP your mouth closed becomes To CONTINUE TO HAVE/MAINTAIN your mouth closed).  This is because this use is the same as "CONTINUE TO MAINTAIN".  

I hope this helps. Feel free to message me if you want to see if your usage is correct.  

What is the context of your sentence?  You are probably confusing to do and to make.

When your mother asks you to stop yelling inside the house, do you keep doing it?
