Which candy bar has the same name as our galaxy?

The candy bar with the same name as our galaxy is Milky Way.

The Milky Way bar was created by Frank C. Mars in the United States and introduced nationally in the 1920s. The American version consists of soft nougat topped with caramel and covered in milk chocolate. Its name sounds astronomical, but the candy was actually associated with the popular malted-milk beverage of the era, not directly named for the galaxy.

The Milky Way name can cause regional confusion. In the United Kingdom and some other countries, a Milky Way bar is a lighter, whipped-nougat product, while the American version is closer in concept to what is sold internationally as a Mars bar. The recipes and branding therefore vary by market.

The galaxy itself is called the Milky Way because, from Earth, its dense band of stars appears as a pale, milky strip across the night sky. The candy borrowed the familiar phrase, making the answer a wordplay connection between astronomy and confectionery.
