Reese's Cups are made by The Hershey Company.

Key points:

• Reese’s Peanut Butter Cups were created by H. B. Reese and later became part of Hershey when the Reese company was acquired.

• The Hershey Company has since marketed and produced Reese’s products worldwide, making Reese’s one of its flagship brands.
