Chef Whitney was inspired by one of her favorite tart treat, Key Lime Pie for this cookie. One bite and you will agree that it tastes just like a slice of key lime pie. It's sweet, tart, creamy, chewy and crunchy. Our Key Lime Pie cookie begins with a buttery graham cracker cookie dough that is stuffed with a creamy lime filling. Once baked, the filling firms up slightly, creating a creamy, gooey center that's bursting with tangy lime flavor. It's finished with a drizzle of lime infused white chocolate.
