Love key lime desserts? These key lime pie bars are a creamy sweet treat! Made with fresh key lime juice, sweetened condensed milk, and a graham cracker crust, these Summer dessert bars are sweet, light, and absolutely delicious.
Preheat oven to 350℉ (175℃). Line an 8×8-inch baking dish with parchment paper, leaving an overhang for easy removal.
MAKE THE CRUST
In a mixing bowl, combine the graham cracker crumbs, sugar, and melted butter. Stir until evenly combined.
Use your hands or a flat bottomed glass to press the crust mixture firmly into the bottom of the prepared pan, ensuring you press into the sides and corners.
Bake the crust in the oven for 8-10 minutes until lightly golden. Remove from the oven, leave the oven on.
MAKE THE FILLING
In a large bowl, whisk the sweetened condensed milk, egg yolks, key lime juice, and lime zest until smooth and fully incorporated. Pour mixture on top of the crust in the pan and spread evenly.
Bake in the oven for 15-18 minutes, or until the filling is just set and still has a slight jiggle in the center.
Remove from the oven and leave to cool completely in the pan. Once cooled, refrigerate for at least 2 hours (or overnight) until fully set.
When ready to serve, lift the bars out of the pan using the parchment paper. Slice into squares. Garnish as desired and serve chilled.
Notes
Graham crackers: If purchasing whole graham crackers, you’ll need around 12 full graham crackers to make 1 1/2 cups of cracker crumbs. Use a food processor to make the fine crumbs.Lime Juice: Bottled or fresh key lime juice can be used in this recipe. Lime juice and lime zest can be used instead of key lime juice.Garnish: A dollop of whipped cream and a little extra zest or a thin slice of lime are good garnish options.
Storage: Store leftover dessert bars in an airtight container in the refrigerator for up to 5 days.
