"Cut off a slice of cake", "cut out a slice of cake" or "cut a slice of cake"?

Question

Which one do I say when I want someone to remove one slice of cake like that

Do I cut it out or cut off or just cut? For example:

Could cut/cut out/cut off one slice of cake for me?

Anyway, is that something a native English speaker would sat?

Answer 1

In that context, we would say cut a slice.

The other phrases exist, but have different uses: neither of them for food, as far as I can think.

Cut off means usually means to cut a piece from the end of something long, usually because the piece is wanted for something.

Cut out means to cut a bad, or rotten, or diseased, portion of something and leave the rest.
