Ingredients

For the Crust:

1 ½ cups graham cracker crumbs
½ cup unsalted butter, melted
¼ cup granulated sugar

For the Filling:

1 can (14 oz) sweetened condensed milk
½ cup fresh key lime juice (about 4-6 key limes)
3 large egg yolks
Zest of 2 key limes

Optional Toppings:

Whipped cream
Key lime wedges
Lime zest

Step-by-Step Instructions

Creating your very own Key Lime Pie Bars is simpler than you might think. Just follow these easy steps:

Preheat Your Oven: Start by preheating your oven to 350°F (175°C).
Make the Crust: In a medium bowl, mix the graham cracker crumbs, melted butter, and sugar together until well combined. Press the mixture into the bottom of an 8×8-inch baking dish, creating an even layer. Bake for 10 minutes until slightly golden.
Prepare the Filling: While the crust is baking, whisk together the sweetened condensed milk, key lime juice, egg yolks, and lime zest in a large mixing bowl until smooth.
Combine and Bake: Once the crust is done, remove it from the oven and pour the key lime filling over the warm crust. Return it to the oven and bake for an additional 15-20 minutes, or until the filling is set and just slightly jiggly in the center.
Cool and Chill: Once baked, let the bars cool at room temperature for about 30 minutes. Then, cover the dish with plastic wrap and refrigerate for at least 2 hours before slicing into squares.
Serve: Cut into squares and serve chilled, optionally topped with a dollop of whipped cream, lime zest, or a small wedge of key lime for garnish.

Helpful Tips

Juicing Key Limes: Fresh key limes can be a bit tricky to squeeze. Try using a citrus juicer for the best results or roll the limes on a countertop before juicing to get more juice out.
For a Thicker Base: If you prefer a thicker crust, add a bit more graham cracker crumbs or butter.
Chill Time: Don’t skip the chilling step! This allows the bars to set properly and enhances the flavors.

Variations of Key Lime Pie Bars

Feel free to get creative! Here are a few exciting variations you might want to try:

Coconut Lime Bars: Add shredded coconut to the crust or filling for a tropical twist.
Berry Swirl: Create a beautiful presentation by swirling in a berry puree (like raspberry or strawberry) into the filling before baking.
Chocolate Drizzle: Drizzle melted dark chocolate on top before serving for a decadent touch.

Common Mistakes to Avoid

Even the best bakers can run into a few pitfalls. Here are some common mistakes to steer clear of:

Overbaking: Keep a close eye on the filling during the last few minutes of baking. Overbaking can lead to a tough texture.
