All of the cupcakes have been eaten by Stephen Curry and me.Simple PresentPresent PerfectPresent Progressive

The sentence "All of the cupcakes have been eaten by Stephen Curry and me" is in the Present Perfect tense.

Here's why:

1. The Present Perfect tense is used to describe an action that happened at an unspecified time before now. The exact time is not important.

2. The structure of the Present Perfect tense is: Subject + have/has + Past Participle. In this case, "All of the cupcakes" is the subject, "have been" is the auxiliary verb (have/has), and "eaten" is the past participle of the verb "to eat".

3. The sentence also includes "by Stephen Curry and me", which is a prepositional phrase indicating who performed the action. This doesn't change the tense of the sentence.

So, the sentence is in the Present Perfect tense.
