Ingredients
  

  • 1 cup graham cracker crumbs
  • 1 quarter cup granulated sugar
  • 1 half cup unsalted butter, melted
  • 2 large eggs
  • 1 14 oz can sweetened condensed milk
  • 1 half cup fresh key lime juice (or regular lime juice)
  • 2 zest limes
  • 1 quarter teaspoon salt
  • none whipped cream (for topping)
  • none lime slices (for garnish)

Instructions
 

  • Preheat the Oven: Begin by preheating your oven to 350°F (175°C) to ensure it’s at the right temperature when you’re ready to bake.
  • Prepare the Crust: In a medium-sized mixing bowl, combine the graham cracker crumbs, granulated sugar, and melted butter. Stir well until the mixture is fully combined and resembles wet sand.
  • Form the Crust: Take the prepared crumb mixture and firmly press it into the bottom of a greased 8x8-inch baking pan. Use the back of a measuring cup or your fingers to create an even layer. Bake in the preheated oven for approximately 10 minutes, or until the crust is golden brown and emits a fragrant smell.
  • Make the Filling: In a separate mixing bowl, whisk together the eggs, sweetened condensed milk, key lime juice, lime zest, and salt. Whisk until the mixture is smooth and well integrated, ensuring there are no lumps.
  • Combine and Bake: Carefully pour the lime filling over the previously prepared crust, spreading it evenly with a spatula. Return to the oven and bake for an additional 15 to 20 minutes, or until the filling is set around the edges but remains slightly jiggly in the center.
  • Cool and Chill: Once done baking, remove the pie bars from the oven and let them cool at room temperature for about 30 minutes. Afterward, refrigerate them for at least 2 hours to allow the bars to firm up completely.
  • Slice and Serve: Once chilled, use the edges of the parchment paper (if lined) to lift the bars from the pan. Cut them into squares or bars using a sharp knife. Top each bar with a luscious dollop of whipped cream and place a lime slice on top for garnish.

Notes

For added flair, sprinkle a touch of extra lime zest over the whipped cream.
