The Transportation Security Administration (TSA) says it was right to confiscate a cupcake late last year because terrorists are creating "novel explosives disguised as common, everyday items."

In a posting on "The TSA Blog" Monday, Bob Burns wrote that the red velvet cupcake confiscated from Rebecca Haines, a 35-year-old university professor, was no ordinary confection.

"I wanted to make it clear that this wasn’t your everyday, run-of-the-mill cupcake," Burns noted. "[U]nlike a thin layer of icing that resides on the top of most cupcakes, this cupcake had a thick layer of icing inside a jar."

He continued: "In general, cakes and pies are allowed in carry-on luggage, however, the officer in this case used their discretion on whether or not to allow the newfangled modern take on a cupcake per 3-1-1 guidelines. They chose not to let it go."

The TSA pointed to two separate plots in 1995 and 2006, where terrorists attempted to use liquid explosives.

"When you think about it, do you think an explosive would be concealed in an ominous item that would draw attention, or something as simple as a cute cupcake jar?" Burns asked.

"This incident may seem like a silly move to many of our critics, but when we can’t be exactly sure of what something is, every officer has the discretion to not allow it on the plane. This is done purely for the safety of everyone traveling."
