Look no further for a delicious and simple recipe for Key Lime Pie Bars. My mom makes this Key Lime Pie every year and everyone raves over it. Simple ingredients, fresh, light and creamy. Perfect for a summer treat. 

I decided to make her famous-to-us recipe for Key Lime Pie into a simple bar dessert. Easy to make and easy to cut and easy to serve. 

What is the difference between a Key Lime and a regular Lime?

Although they may seem to only have a size difference, Key Limes are actually a little more on the sweet side while regular limes are on the tart side. That’s why Key Limes make a perfect fruit for a sweet (and tiny bit tart) dessert. 

What are the ingredients for Key Lime Pie?

Key Lime Pie is made of only a few ingredients. The crust, oh man, the crust. Guess what, two ingredients. Graham Cracker Crumbs and my favorite Hiland Dairy Butter. Nothing better than the quality Hiland products for all my recipes. They make a difference, trust me. 

Then the filling. Three ingredients for this. Okay, 4 if you count the lime zest. You can juice a key lime yourself or just grab some bottled key lime juice. Make your life easy. 

I shouldn’t play favorites, but a homemade whipped topping is alway on top of my list. Homemade whipped cream is key to this recipe for Key Lime Pie so grab some Hiland Dairy Heavy Cream while you are at the store picking up ingredients.
