Ingredients
  

For the Crust

  • 1 1/2 cups crushed Ritz crackers A buttery twist for the crust; substitute with regular saltines if needed.
  • 1/2 cup graham cracker crumbs For added texture; whole-grain options can be used for a healthier option.
  • 1/3 cup brown sugar Adds a rich flavor that balances the tartness.
  • 1/2 cup unsalted butter, melted Ensure it's at room temperature for easier mixing.

For the Filling

  • 1 cup sweetened condensed milk Recommended brands include Eagle Brand and Carnation.
  • 1/2 cup key lime juice Freshly squeezed for authentic flavor or bottled if short on time.
  • 3 large eggs Use room-temperature eggs for better incorporation.
  • 1 teaspoon zest of lime Adds depth of flavor; don’t skip this step!

Topping

  • Whipped cream Optional; can be homemade or store-bought.

Instructions
 

Preparation

  • Preheat your oven to 350°F (175°C) for even baking.
  • In a mixing bowl, combine the crushed Ritz crackers, graham cracker crumbs, brown sugar, and melted butter. Stir until combined and crumbly.
  • Press the crust mixture into the bottom of a greased 9×9-inch baking dish to create an even layer, ensuring it’s packed tightly.

Making the Filling

  • In another bowl, whisk together the sweetened condensed milk, key lime juice, eggs, and lime zest until smooth, ensuring no lumps remain.
  • Pour the key lime filling over the crust, spreading it evenly with a spatula.

Baking

  • Bake for 20-25 minutes, or until the filling is set but still slightly jiggly in the center.

Cooling and Chilling

  • Allow the bars to cool at room temperature for about 30 minutes, then refrigerate for at least 2 hours before slicing.

Serving

  • Serve chilled, topped with whipped cream if desired.

Notes

These bars can be stored in the refrigerator for up to a week or frozen for up to three months. You can also prepare the crust a day in advance.
