These Heart Shaped Valentine's Day Junior Mints are the best! Junior Mints are, first off, the yummiest drugstore candy. Or actually the second best after the glorious and unbeatable Reese's Peanut Butter Cup. In this holiday version, the Junior Mint is super festive in the shape of a heart. In addition, some are filled with the classic white peppermint and others are filled with a surprising and jewel-like red filling. (I've written about these enthralling secret colored fillings previously). It's a fantastic treat!
