I have. Haydels Bakery makes them. Very light and flaky, topped with pecans and icing. Really rich!
You can click the beginnings of the story underneath the price and it will give you an idea about the name.
They actually make a chocolate doberge cake I like better. My kids love their homemade chewing gum.
If you are familiar with the area they are on Jefferson highway headed towards Harahan from New Orleans.
