The shortcake pieces are imprinted with faces (five types) that have holes where the eyes and mouth would go which allows one to see the filling.

Involved in the original design process was Project and Design Engineer Peter Stitson for the biscuit making machinery in the late 60s or 70s when the company was known as Nabisco Frears.

Happy Face was discontinued as a separate product in the mid 2010s and since were only found in Family Circle biscuit packs until 2020.

It wasn't until May 2023 that McVities confirmed that production of Happy Faces has been resumed and the biscuit has started reappearing on supermarket shelves under the BN Brand.
