> Unit sales: 60,808,770
> Dollar sales: $65,632,620

> Introduced: 1946
> Company: Hershey

When Almond Joy was first introduced in 1946, it sold for 10 cents a bar. The candy, which includes coconut and almonds, is significantly more popular than Hershey’s similar chocolate bar, Mounds, which does not appear at all in the 20 most popular chocolate brands. In 1988, Hershey purchased Peter Paul’s U.S. operations, which at that point had already merged with those of Cadbury Schweppes.

> Average price per unit: $1.12
> Introduced: 1994
> Company: Hershey

Hershey’s Cookies ‘n’ Creme — a white chocolate bar containing chocolate cookie bits — is the most popular of the company’s recently released products. The chocolate bar debuted in 1994, and it did not take long before it became a national favorite. In the 52 weeks ending March 18, 2012, Hershey sold more than 73 million Cookies ‘n’ Creme units, which was 10% less than the year before.

8. Milky Way
> Unit sales: 80,053,290
> Dollar sales: $76,982,430
> Average price per unit: $0.96
> Introduced: 1923
> Company: Mars

Milky Way Bars — referred to as MARS Bars outside the U.S. — are made of caramel and nougat, wrapped in chocolate. The number of Milky Ways sold in the less than 3.5 oz chocolate category does not fully reflect the candy’s popularity. Milky Way is the fourth-most popular candy in the more than 3.5 oz category, and the fifth-most popular among snack size chocolate candies. The Milky Way Bar, first released in 1923, was Mars’s first candy bar. It is now among the country’s favorites. In 2005, Americans ate more than 200 million Milky Ways.

> Dollar sales: $101,472,500
> Average price per unit: $1.07
> Introduced: 1932
> Company: Mars

The concept behind 3 Musketeers bars is simple enough: light nougat wrapped in milk chocolate. The candy has been a popular choice among Americans for the past 75 years. It sold more than 94 million units in the 52 week period ending March 18 — and that’s only in the less than 3.5 oz category. The brand is also the ninth-most popular in the snack size category, with more than 14 million units being sold in the same 52 week period. Part of the candy’s appeal may be its relatively good nutritional facts. According to Mars, 3 Musketeers has 45% less fat than the average of the leading chocolate brands.

In the 52 weeks that ended March 18, 2012, there were more than twice as many units of Twix sold than Milky Ways. Twix is also the eighth-most popular snack size candy. Twix — named for “twin sticks” — is the second-most expensive candy among the most popular chocolate candies.
