Who needs a summery dessert for their cookout tomorrow?? These key lime bars are super easy, light, refreshing and perfect to take to your cookout when you don’t want a super heavy dessert out in the heat!
I actually first made these for a friend’s rehearsal dinner years ago. They wanted a variety of dessert bars, and I tested many recipes and these were some of my favorite. They are tart and delicious. They would be perfect for a baby or wedding shower, too!
