I had a hankering for Lemon bars and thought why not shake it up and make Key Lime Bars? I had a bowl of limes just begging to be used and you know how I just can’t leave a recipe alone.
Key Lime Bars with Lime Zest Recipe
Give me a dessert that makes me pucker, like my Strawberry Lemonade Cake or these Pina Colada Bars and I’m a happy girl!
Of course, that doesn’t mean I’m not happy when someone gives me something with chocolate like my Dark Chocolate Fruity Nut Bites. And we all know my obsession with Peanut Butter and Chocolate together! Now I’m craving my Peanut Butter and Chocolate Layered Dessert! Dang it! I’ll be heading back to the kitchen. 
There are so many recipes out there for Lemon Bars and Lime Bars… some are creamy lemon bars and some have frosting… or a graham cracker crust. I decided to take a basic lemon bar recipe, but use key lime juice and zest instead.
I was inspired by an old recipe from one of my Taste of Home magazines. Love those!
Can I use Lime Juice Instead?
Yes, of course. Key Lime juice or fresh juice would be better of course, but don’t let that get in your way of baking this delicious bar recipe.
I took their Bake Sale Lemon Bars and turned them into my Key Lime Bars with Lime Zest. Simple!
How to Make Key Lime Bars
Their recipe called for a 13 x 9 pan, but if I were to make them again, I may try using a smaller baking dish for thicker Key Lime Bars. But then again… maybe not, because they really were the perfect amount for a treat.
The crust was flaky and the top had a very slight crunch before biting into the soft middle. So dang good!
