This doesn't make sense. Are some words missing or something?
The subject (muffins) is certainly plural, but it's not first person.

1st: I,we
2nd: you
3rd, he,she,it,they

Given that, what does it have to do with tenses?
Well, I guess it does in this case. As far as I recall, the verb "to be" is the only one where the past tense differs between singular and plural. Person still doesn't matter.
Third person plural. " the muffins are fresh. THEY(3rd person plural) were made an hour ago."
