Start with store-bought strawberry cake mix and fix it up with simple ingredients you most likely already have on hand—staples like eggs, butter, sugar, and milk. Then top the cookies with festive icing and sprinkles. (Better yet, ask little kitchen helpers to do it as a fun afternoon activity.) While these make the perfect Valentine's Day treat, they work just as well when customized to fit your vision. Make the cookie shape, icing, and sprinkles match whichever party theme you have in mind. These Heart Cookies are a surefire way to make your party spread look oh-so pretty—and tasty to boot!
