Is it cream filled?

It is Mardi Gras season in Louisiana and this means that we are headed to Mardi Gras balls and eating lots of King Cake. I decided to bring a large King Cake up north to Virginia to share with my co-workers and I decided to carry it on the plane. It is its own separate box in my carry on entourage. Passing through airport security this morning was interesting as a result. As you probably know, liquids or gels are not allowed. So when I asked the TSA official if the cake was ok, her response was: "Is it cream filled?"
