Candy brand with a Big Cup variety

REESES

This peanut butter-filled treat comes in shapes like trees and eggs, and its classic cups are wrapped in orange. Look for the name that starts with a double letter.

This clue points to Reese’s, the well-known candy brand famous for its peanut butter cups. The "Big Cup" part refers to one of their product varieties—a larger version of their classic peanut butter cup. Since the clue names both the brand and a specific type, the answer is simply the brand’s name, spelled as REESES (with two E’s at the end, as it appears on packaging). It’s a straightforward reference with no hidden wordplay.
