Ingredients:
- 1 ½ cups graham cracker crumbs: For a crunchy base that complements the creamy filling.
- ½ cup unsalted butter: Melted, to bind the crust together.
- ½ cup granulated sugar: Adds sweetness to the crust.
- 2 large eggs: Essential for the filling’s structure.
- 1 can (14 oz) sweetened condensed milk: Provides creaminess and richness.
- ½ cup fresh key lime juice: The star ingredient that gives these bars their signature tartness.
- Zest of 2 key limes: Enhances the flavor with a burst of citrus aroma.
- Powdered sugar: For dusting, optional but adds a nice touch.
Suggested Substitutions:

Step-by-Step Instructions
Step 1: Preheat the Oven
Preheat your oven to 350°F (175°C). This ensures the crust bakes evenly and sets nicely.
Step 2: Prepare the Crust
In a medium bowl, combine 1 ½ cups of graham cracker crumbs, ½ cup of melted unsalted butter, and ½ cup of granulated sugar. Mix until well combined. Press this mixture firmly into the bottom of a greased 8×8-inch baking dish to form an even layer.
Step 3: Bake the Crust
Bake the crust in the preheated oven for 8-10 minutes or until it’s lightly golden. This step enhances the flavor and texture of the crust.
Step 4: Make the Filling
In a separate bowl, whisk together 2 large eggs, 1 can (14 oz) of sweetened condensed milk, ½ cup of fresh key lime juice, and the zest of 2 key limes until smooth and well combined.
Step 5: Pour the Filling
Once the crust is done baking, remove it from the oven and pour the key lime filling over the hot crust. Spread it evenly with a spatula.
Step 6: Bake Again
Return the baking dish to the oven and bake for an additional 10-12 minutes. The filling should be set but will continue to firm up as it cools.
Step 7: Cool and Chill
Allow the bars to cool at room temperature for about 30 minutes, then refrigerate for at least 2 hours before slicing. This chilling period is crucial for achieving the perfect texture.
Step 8: Serve
Once chilled, dust with powdered sugar if desired, slice into squares, and serve chilled. Enjoy the refreshing taste of your homemade Key Lime Pie Bars!
