Whippet cookies are produced in Montreal, Quebec, Canada.
They consist of a biscuit base topped with marshmallow-like filling and then coated in a hard shell of pure chocolate.

Whippet cookies first came to the market in 1927, although they had been produced and distributed by Viau under the name "Empire" as early as 1901.
Today, the cookies are still produced in Montreal at the east end of the Viau factory, which is now owned by Dare Foods.
They are currently available with both dark chocolate and milk chocolate coatings, and with several flavors of artificial fruit jam filling inside the marshmallow-like filling.

The cookies are similar to Mallomars of New York City.
They also bear a striking resemblance to Tunnock's Tea Cakes as well as Krembos.
However, the Tunnock tea cake does not have the same kind of chocolate and a different type of filling.

The Whippet cookie is a distinct part of Montreal culture because it does not travel well outside its area of production.
This is partly because the pure chocolate melts very easily (compared with compound chocolate) and therefore they require refrigerated transport in summer.
Furthermore, the combination of the hard chocolate shell and the air-filled inner marshmallow make them self-destruct when placed in the unpressurised or semi-pressurised cargo section of an airplane.
However, they are currently available at various grocery locations throughout Canada and the US.

Though usually known by their proper trade name "Whippets", these biscuits are also popularly referred to in the Montreal area as "Nun's Farts" in the Anglophone community.
Though they bear absolutely no resemblance to the Quebec pastry confections called pets de soeurs, it has been suggested that the combination of dark chocolate coating and white marshmallow filling is evocative of the black and white habits of certain orders of Quebec nuns.
This, in conjunction with their light and airy texture, may have given rise to the cheeky Anglo-Quebecois moniker.
It is not used by the francophone community.

An episode of the Canadian science program How It's Made showed the production process behind the cookie.
However, many aspects of the production process (the amount of marshmallow filling, the ingredients, etc.)
were not revealed.
 The show's narrator described these aspects as "classified information".
As Canadian law requires an ingredient list on each package, the amount of confidential information involved is limited.

Another Canadian cookie, "Viva Puffs", is produced by Dare Foods in five flavours.
Viva is a trade name; these confections have been known in (English) Canada for at least 50 years as "chocolate puffs".
