Asked by Susie Frost

Is the sentence Cookies are my Kryptonite an allusion or a metaphor?

It's both. "Kryptonite" alludes to the Superman stories (an allusion), and the sentence uses that allusion to make a direct comparison—cookies = a personal weakness—so it functions as a metaphor.

You can call it an allusive metaphor (or idiom): a metaphor grounded in a cultural reference.
