These Irresistible Key Lime Pie Bars are just that—irresistible! Made with the perfect graham cracker crust, a creamy, zesty filling, and a dusting of powdered sugar, they’re the perfect cool and refreshing dessert for summer.
Spray an 8-inch or 9-inch square pan with cooking spray and line with parchment paper.
Combine graham cracker crumbs, butter, and sugar in a small bowl and stir until combined.
Press the graham cracker crumb mixture into the bottom of the prepared pan and press down firmly. Use the bottom of a measuring cup to really pack it in.
Bake the graham cracker crust for 7 minutes. Remove from the oven and let cool.
