Airheads is celebrating their 30th birthday and they're throwing a cake party. The taffy-like candy has been around for three decades and, in celebration of this, is releasing a limited-edition Birthday Cake flavor.

Customers can also win themselves some free birthday swag, including cash, by entering here.

You can find the Birthday Cake Airheads at participating retailers in both a pack of six or a pack of ten.

Our personal favorite was always the white mystery flavor. You just never know with that one...
