I miss your cookies. I haven’t tasted none like yours before.
I miss your cookies. I haven’t tasted any like yours before.
None already has a negative meaning, so do not use it after a negative verb such as haven’t.
After a negative verb, use any: ‘I haven’t tasted any like yours before.’
We can use none with an affirmative verb: ‘I have tasted none like yours before.’ However, this sounds more formal.
