Barry's Bakery of Tolleson, AZ makes a product called "Mini Peaks".

They're shipped in bags with the words, "100 Calories per bag" because each Mini Peak contains only 1 calorie.

They come in two varieties, vanilla and chocolate.

A Mini Peak looks similar in shape to a Hershey's Kiss, but is a simple concoction of sugar and egg whites, along with some salt and "cream of tartar". You can scarf down a whole bag and not add too much to your circumference.

They've been out for awhile now, and are available in stores across the country. Visit the company's store locator: http://www.barrysbakery.com/locator/
