Mallomars

Extracted from the Wikipedia article Chocolate-coated marshmallow treats.
United States
Mallomars are generally available from early October through to April. They are not distributed during the summer months, supposedly because they melt easily in summer temperatures, though this is as much for marketing reasons as for practical ones. Devoted eaters of the cookie have been known to stock up during winter months and keep them refrigerated over the summer, although Nabisco markets other chocolate-coated cookie brands year-round. (Those brands include Pinwheels, which also combines chocolate, cookie, and marshmallow.) Eighty-five percent of all Mallomars are sold in the New York metropolitan area. They are produced entirely within Canada, at a factory in Scarborough, Ontario.
