The main reason is was taken away from the passenger was due to the amount of icing (categorized as a gel by the TSA) that falls under the 'liquid' categorization and didn't adhere to 3-1-1 standards. The odd thing is that these cupcakes cleared on one leg of the trip (from my home airport of Boston Logan), but not the other.

I know I would be totally bummed to lose out on one of these beauties. I have to say that I love this cupcake in a jar concept, it looks absurdly delicious and the packaging couldn't be sweeter (I'm a sucker for a mason jar). I'm psyched to know that these are produced right here in Massachusetts at Wicked Good Cupcakes, which I will have to try out very soon. Maybe a 3.4 ounce jarred cupcake is in order for travels? They could name it 'Cupcakegate'!
