TJ's has a Mousse cake that is seasonal.
it seems to be the same basic cake in different forms.
Ive had it at Christmas , Valentine's day and Easter.
I might have appeared at Thanksgiving but I missed it if it did
its not around long , which in this case is a good thing
it delicious , and plan for possibly eating the entire unit w an ice cold glass of milk
