How to make Irresistible Key Lime Crack Bars
Step 1: Prepare the oven and pan.
Preheat oven to 350°F (175°C). Line a 9×13 inch baking pan with parchment paper, leaving an overhang on the sides for easy removal.
Step 2: Make the crust.
In a medium bowl, combine graham cracker crumbs, melted butter, and granulated sugar. Press the mixture firmly into the bottom of the prepared pan to form a crust.
Step 3: Bake the crust.
Bake the crust for 10 minutes. Remove from oven and let cool slightly.
Step 4: Prepare the filling.
In a large bowl, whisk together sweetened condensed milk, key lime juice, and key lime zest until smooth and well combined.
Step 5: Assemble and bake.
Pour the key lime mixture over the partially baked crust, spreading evenly.
Step 6: Bake the bars.
Bake for 15-20 minutes, or until the filling is set but still slightly jiggly. The edges should be lightly golden.
Step 7: Cool and chill.
Let the bars cool completely in the pan on a wire rack. Then, refrigerate for at least 2 hours before cutting into squares. Dust with powdered sugar before serving, if desired.
Chef’s Tip: Don’t overbake the filling; a slight jiggle ensures a creamy texture after chilling.
Tips for Success
- Use fresh key lime juice for the most authentic and vibrant flavor.
- Press the graham cracker crust firmly and evenly for a sturdy base.
- Allow the bars to cool completely before refrigerating to prevent a soggy crust.
- For easier cutting, use a warm, wet knife.
