Key Lime Pie Bars

I LOVE key lime pie…it’s my favorite pie of all time! The sweet and tart filling gets me every time! These key lime pie bars are simply the bar version of the classic dessert and are just as delicious. The sweet graham cracker crust is baked to perfection and then topped with a layer of smooth key lime pie filling. The filling is my favorite because it’s creamy, tangy, and loaded with zesty lime flavor. And any dessert recipe that uses sweetened condensed milk is a win in my book!

If you love key lime anything like I do, then I have some incredible recipes for you to try! This no-bake key lime pie is an easy summer dessert to make. I also love this cheesecake and my kids always request this key lime poke cake.
