The Wonka Bar is both a fictional candy bar, introduced as a key story point in the 1964 novel "Charlie and the Chocolate Factory" by Roald Dahl, and a type of consumer product candy bar inspired by the fictional confection.
 Wonka Bars appear in both film adaptations of the novel, "Willy Wonka & the Chocolate Factory" (1971) and "Charlie and the Chocolate Factory" (2005), and the play "Charlie and the Chocolate Factory the Musical" (2013) each with different packaging.
The Idaho Spud is a candy bar made by the Idaho Candy Company.
 It has been produced since 1918 and is distributed throughout the Pacific Northwest region of the United States.
 The wrapper of the product bears the slogan "The Candy Bar That Makes Idaho Famous."
 The bar's inventor, Thomas "T.O." Smith founded the Idaho Candy Company in 1901, and went on to create numerous confectionery concoctions such as the Old Faithful Bar (1925) and the Cherry Cocktail Bar (1926).
 These items are still in production today.
Skor is a candy bar produced by The Hershey Company.
 It was first marketed in the United States in 1981 and later launched in Canada in 1983.
 "Skör" (with umlaut dots over the "o") is Swedish for "brickle", and the crown that appears in the product's logo is identical to that found in the Swedish national emblem of "Tre Kronor" ("Three Crowns").
 It was originally intended as the competition for the Heath bar produced by the Heath Company and, later, the Leaf Candy Company.
 Despite Hershey's acquisition of Leaf, Inc., in 1996 and subsequent production of the Heath bar under the Hershey name, the company continues to market the Skor bar.

The Milky Way bar is a chocolate-covered candy bar manufactured and distributed by the Mars confectionery company.
 The American version of the Milky Way bar is made of chocolate-malt nougat topped with caramel and covered with milk chocolate and sold as the Mars bar everywhere else.
 The global Milky Way is a different chocolate candy bar similar to the American 3 Musketeers.
3 Musketeers is a candy bar made in the United States and Canada by Mars, Incorporated.
 It is a chocolate-covered fluffy whipped chocolate bar.
 The 3 Musketeers Bar was the third brand produced and manufactured by M&M/Mars, introduced in 1932.
 Originally, it had three pieces in one package, flavored chocolate, strawberry and vanilla; hence the name, which was derived from the novel "The Three Musketeers".
 Rising costs and wartime restrictions on sugar saw the phasing out of the vanilla and strawberry pieces to leave only the more popular chocolate.
 Costing five cents when it was introduced, it was marketed as one of the largest chocolate bars available, one that could be shared by friends.
Mr. Big is the largest sized candy bar produced by Cadbury in Canada, hence the name.
 The standard bar is made of a layered vanilla wafer coated in caramel, peanuts and rice crisps covered in a brown simulated chocolate-like coating.
 Because of Canada's higher chocolate standards compared to other areas of the world, it is not considered a "chocolate bar" and is labeled instead as a "candy bar".
 The bar is the length of two "standard"-sized bars – around 20 centimeters (8 inches) long.
 Additional varieties include Mr. Chew Big, Mr. Big Fudge, and Mr. Big with Maple.
