The peanut butter blossom cookie goes way back to the late 1950s when it was first created as a simple peanut butter cookie, rolled in granulated sugar and topped with chocolate candy. While rumor has it that an Ohio home baker used the Hershey's Kisses to top these cookies as a creative substitute for chocolate chips, one thing's for sure - these soft and chewy cookies "blossom" into pillowy mounds of deliciousness when baked, ideal for placing your favorite Hershey's Kisses in the center while still warm!
