Ingredients:
– 15 sheets graham crackers, (or 30 squares)
– 2 tablespoons sugar
– pinch salt
– 6 tablespoons unsalted butter, (melted)
– 6 ounces cream cheese, (room temperature)
– 1 (14-ounce) can sweetened condensed milk
– 4 egg yolks

– ½ teaspoon vanilla extract
How to Make Key Lime Pie Bars
Step 1: Preheat the Oven
Preheat your oven to 350°F. Line a 9×9-inch pan with aluminum foil or parchment paper, making it easier to remove the bars later.
Step 2: Prepare the Crust
In a food processor or large Ziploc bag with a rolling pin, crush the graham crackers until fine crumbs form.
Step 3: Mix the Crust Ingredients
In a medium mixing bowl, combine the crumbs, sugar, salt, and melted butter. Mix until everything is well combined. Press the mixture evenly into the bottom of the lined pan. Place it in the oven and bake for 10 minutes.
Step 4: Make the Filling
While the crust is baking, beat the cream cheese in a large mixing bowl until smooth. Add the sweetened condensed milk and mix until fully combined.
Step 5: Incorporate Eggs & Flavorings
Add egg yolks one at a time, mixing well after each addition. Then add lime zest, key lime juice, and vanilla extract. Mix until everything is well blended.
Step 6: Bake Again
Pour the filling over your hot baked crust. Return it to the oven and bake for 15-18 minutes or until set—make sure not to let it brown on top.
Step 7: Chill & Serve
Remove from oven and chill in the refrigerator for at least 2 hours before serving. Once chilled, cut into bars and enjoy! Store any leftovers in an airtight container in the refrigerator for up to 5 days.

How to Perfect Key Lime Pie Bars
To make your key lime pie bars truly exceptional, consider these helpful tips.
-
Use Fresh Ingredients: Using fresh key limes instead of bottled juice will provide a more robust flavor.
-
Chill Properly: Allowing the bars to chill for at least 2-4 hours ensures they set properly and enhances their flavor.
-
Don’t Overbake: Keep an eye on the baking time; overbaking can lead to a dry filling. It should be just set but not browned.
-
Add More Zest: For an extra zing, feel free to add more lime zest than the recipe calls for. It enhances both aroma and taste.
-
Choose Quality Graham Crackers: Opt for high-quality graham crackers for the crust to achieve that perfect buttery base.

Common Mistakes to Avoid
When making key lime pie bars, it’s easy to run into a few common pitfalls. Here are some mistakes to steer clear of for a delicious outcome.
- Using stale graham crackers: Fresh graham crackers yield a better crust. Check the expiration date before use.
- Overmixing the filling: Mixing too much can incorporate air, leading to cracks. Mix just until combined for a smooth texture.
- Not chilling adequately: Skipping the chill time results in a gooey filling. Always chill for at least 2 hours before serving.
- Ignoring oven temperature: An oven that is too hot can brown the top. Use an oven thermometer to ensure accuracy.
- Cutting bars too soon: Cutting before they set can make a mess. Wait until they are fully chilled for clean slices.
