- Key lime juice (1/2 cup): The star ingredient that brings that bright, tangy kick.

How to Make Key Lime Pie Bars Recipe
Step 1: Prepare the crust
Start by preheating your oven to 350°F (175°C) and lining an 8×8-inch baking dish with parchment paper, leaving an overhang to lift the bars out easily later. Mix the graham cracker crumbs, sugar, and melted butter until your mixture is evenly moistened. Press it firmly and evenly into the bottom of your pan—this crust will be the wonderful crunchy base that supports the filling beautifully. Bake it for 10 minutes to set and slightly brown, then let it cool a bit while you make the filling.
Step 2: Whisk together the filling
In a separate bowl, whisk the egg yolks until smooth, then add the sweetened condensed milk, key lime juice, and lime zest. Whisk until the mixture is fully combined and silky. The vibrancy of the lime zest and juice in this step gives you that signature tartness we all love in a Key Lime Pie Bars Recipe.
Step 3: Bake the bars
Pour the luscious filling evenly over the cooled crust. Bake the entire pan for about 15 to 18 minutes, or until the center is just set. It should jiggle slightly but not be liquid. Remove from the oven and let it cool completely at room temperature.
Step 4: Chill thoroughly
Once cooled, place the bars in the refrigerator for at least 2 hours. Chilling is critical—not only does it enhance the flavors, but it also helps the bars firm up enough for clean slicing. Patience here pays off with perfect bites every time!
Step 5: Serve and enjoy
Use the parchment paper to lift the bars out of the dish, then cut into squares. Top with whipped cream and a sprinkle of extra lime zest, if you like. This finishing touch adds a creamy note and a pop of color that makes your Key Lime Pie Bars Recipe even more inviting!
How to Serve Key Lime Pie Bars Recipe
Garnishes
Adding a dollop of freshly whipped cream and a light dusting of key lime zest instantly elevates the appearance and flavor of your bars. For a bright contrast, thin slices of lime or a few fresh mint leaves make an elegant garnish that’s sure to impress.
Side Dishes
These bars shine as a stand-alone treat but pair wonderfully with a scoop of vanilla ice cream or a refreshing fruit salad. A lightly sweetened berry compote adds a lovely color and complements the tartness perfectly, making your dessert plate feel truly special.
Creative Ways to Present
Try serving the bars in colorful mini cupcake liners for individual portions at parties. Alternatively, arrange them on a pretty platter with a drizzle of raspberry sauce or a sprinkle of toasted coconut for a tropical twist. Presentation can be as fun and bright as the dessert itself!
Make Ahead and Storage
Storing Leftovers
Keep any leftover Key Lime Pie Bars Recipe covered in an airtight container in the refrigerator. They will stay fresh and delicious for up to 4 days, making them a convenient and delightful treat to enjoy later.
Freezing
If you want to store them longer, these bars freeze beautifully. Slice them first, place the pieces separated by parchment paper in an airtight freezer bag or container, and freeze for up to 2 months. Thaw in the refrigerator before serving.
Reheating
Since this is a chilled dessert, reheating isn’t recommended. Instead, allow frozen bars to thaw completely in the fridge for clean slices and the best texture. Serve cold or at room temperature for maximum enjoyment.
FAQs
Can I use regular lime juice instead of key lime juice?
Absolutely! While key lime juice gives the bars their distinct authentic flavor, regular lime juice is a fine substitute that still provides a delicious tartness. Just expect a slightly different but still refreshing taste.
Why do I need to chill the bars before slicing?
Chilling solidifies the filling so it holds together when cut. Without proper chilling, the bars may be too soft or messy, making it tricky to get clean, neat squares.
Is there a way to make the crust gluten-free?
You can swap the graham cracker crumbs with gluten-free graham cracker crumbs or crushed gluten-free cookies. Just be sure to keep the sugar and butter amount the same for the best crust texture.
Can I prepare Key Lime Pie Bars Recipe ahead of time for a party?
Definitely! These bars are fantastic make-ahead desserts. You can prepare and bake them the day before your event, chilling overnight for incredible flavor and convenience.
What’s the best way to zest limes efficiently?
Use a fine Microplane zester to get vibrant lime zest without the bitter pith. Zest only the green part of the skin and avoid the white underneath for the best flavor.

Description
These Key Lime Pie Bars combine a buttery graham cracker crust with a tangy, creamy key lime filling for a refreshing dessert perfect for summer or any citrus lover. Topped optionally with whipped cream and extra lime zest, these bars are easy to prepare and chill for a delightful treat with a smooth, balanced sweet-tart flavor.
Ingredients
Crust
- 1 and 1/2 cups graham cracker crumbs
- 1/4 cup granulated sugar
- 1/2 cup unsalted butter, melted
Filling
- 4 large egg yolks
- 1 can (14 ounces) sweetened condensed milk
- 1/2 cup key lime juice (fresh or bottled)
- 1 tablespoon key lime zest
Topping (Optional)
- Whipped cream for topping
- Extra lime zest for garnish
Instructions
- Prepare the Crust: Preheat your oven to 350°F (175°C) and line an 8×8-inch baking dish with parchment paper, leaving an overhang on the sides for easy removal. In a medium bowl, mix the graham cracker crumbs, granulated sugar, and melted butter until the crumbs are evenly moistened. Press this mixture firmly and evenly into the bottom of the prepared pan to form the crust.
- Bake the Crust: Place the crust in the preheated oven and bake for 10 minutes to set. Once baked, remove it from the oven and allow it to cool slightly while you prepare the filling.
- Make the Filling: In a separate bowl, whisk together the egg yolks, sweetened condensed milk, key lime juice, and key lime zest until the mixture is smooth and fully combined. This creates the tangy, creamy filling that defines the bars.
- Assemble and Bake: Pour the filling over the slightly cooled crust, spreading it evenly. Return the pan to the oven and bake for 15 to 18 minutes, or until the center is just set but still slightly jiggly. This ensures a creamy texture once chilled.
- Cool and Chill: Remove the bars from the oven and let them cool to room temperature. Then refrigerate for at least 2 hours or until fully chilled and firm enough to slice cleanly.
- Serve: Using the parchment paper overhang, lift the bars out of the pan and cut into 9 squares. Optionally, top each bar with whipped cream and sprinkle extra lime zest for a fresh garnish before serving.
Notes
- For a stronger lime flavor, consider increasing the lime zest to 1 and 1/2 tablespoons.
- If fresh key limes are unavailable, bottled key lime juice or regular lime juice can be used, though the flavor will be slightly different.
- Chill bars thoroughly before slicing to ensure clean, neat cuts.
- Store any leftovers in the refrigerator for up to 4 days to maintain freshness and texture.
