Key Lime Bars are an easy, mouthwatering way to get your citrus fix! Made with a buttery shortbread crust and an ooey-gooey layer of lime goodness, you’ll want to make this treat for all your summer get-togethers!
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
