How To Make Key Lime Bars
1. The first step is to preheat oven to 350 degrees F and prep your baking pan with parchment paper and cooking spray.
2. Then throw together that flaky shortbread crust. Combine flour, sugar, butter, and a dash of salt, chill for 15 minutes, then bake until barely golden brown.
3. For that scrumptious lime layer, all you need are eggs, sugar, flour, key lime juice, and lime zest. Mix together, pour into crust, then bake again for 25 minutes to 30 minutes. Regular limes can also be used if you can’t find key limes.
4. After the bars have cooled, sprinkle a little bit of powdered sugar on top. That’s it!
I never leave recipe reviews, but I had to, these are amazing! I made it to the letter and it came out perfect. I used the juice and zest of four limes and it hit the spot. It’s super punchy and packed with lime flavor yumm!

Can Lime Bars Be Frozen?
Yes, they certainly can. In fact, they are actually really great frozen. To freeze them, simply allow the bars to cool completely and wrap tightly in plastic wrap or aluminum foil and freeze for up to 3 months.

Steps
Shortbread Crust
Preheat the oven to 350°F. Line a 9x13-inch baking pan with a sheet of parchment paper, then grease well and set aside.
With a hand mixer or in a stand mixer, cream the butter for 2-3 minutes until pale and fluffy. Add the sugar and flour and mix well.
Transfer the dough to the prepared baking pan. Spread it into an even layer with your fingers. Chill for 15 minutes, then bake in preheated oven for 15-20 minutes until just barely golden brown. Cool.
Lime Custard
In a large bowl, whisk together all ingredients until well incorporated. Pour the mixture over the cooled crust.
Bake for 25 to 30 minutes at 350°F until the custard is set. Remove from the oven and let cool before slicing and serving. Dust with powdered sugar as desired and serve. You may also chill the bars and serve them cold.
Notes
- Shelf Life: Room temperature if served the day they are made, otherwise, store in the refrigerator for up to 4 days.
- To Freeze: Allow the bars to cool completely and wrap tightly in plastic wrap or aluminum foil and freeze for up to 3 months.
- Key Lime Pie Bars: If you really want to get fancy, just add a layer of meringue, toast, and enjoy.
- No Key Limes? That's okay, this recipe is still delicious when made with traditional limes
