National Peppermint Pattie Day

Chill out... It's National Peppermint Pattie Day!

For more than 70 years, the chocolate candy with a minty middle has brought smiles to faces.

Back in the 1940s, ice cream maker Henry C. Kessler wanted to expand his company's list of treats so he added the cool candy to his brand.

Now, Hershey's delivers the "sensation" of the smooth dark chocolate pattie with a burst of peppermint in the middle.
