This Key Lime Pie Yogurt Bark is a family favorite for cooling off on warm afternoons while sneaking in a protein boost. Creamy Greek yogurt makes the bark satisfyingly rich, while fresh lime and crunchy toppings keep every bite exciting. You can whip up a batch in minutes and simply freeze until set for a healthy, delicious treat everyone enjoys.
My family first tried this on a steamy July day. Since then it has become our favorite cool down snack especially after a swim in the backyard.

My youngest always begs to sprinkle on extra coconut It is so fun seeing everyone create their own section on the bark and those lime scented hands are a summer memory in our kitchen
Storage Tips
Always store yogurt bark in a single layer or with parchment between layers in a tightly sealed container in your freezer. The bark stays freshest and crisp for up to two weeks but disappears much faster in my house
Ingredient Substitutions
You can make this bark with full fat or low fat Greek yogurt for your preferred texture. Any dairy free yogurt will work just as well and you can swap honey in for swerve if you want a more classic pie sweetness. Add any nut free granola instead of graham crackers or dried fruit and nuts if you want to change it up
Serving Suggestions
Serve straight from the freezer as a snack or refreshingly healthy dessert. Make a yogurt bark platter as a shareable summer treat for gatherings or bake sales. It is also delicious broken up over a bowl of fruit salad for a quick parfait
Cultural Inspiration
Inspired by classic southern key lime pie this bark recipe brings the tang and zest of fresh key limes without turning on the oven. The toasted coconut and graham bring nostalgic flavors in a modern healthy way. This has become a staple for family BBQs and hot weather parties
