Ingredients You’ll Need
Simple ingredients form the foundation of this recipe, each playing a vital role to balance the texture and flavor of your key lime pie bars. From the crumbly crust to the silky filling, everything comes together beautifully.
- 1 ½ cups graham cracker crumbs: Provides the perfect crunchy base with a subtle sweetness.
- ¼ cup granulated sugar: Adds gentle sweetness to enhance the crust’s flavor.
- 6 tablespoons unsalted butter, melted: Binds the crust together and delivers buttery richness.
- 2 (14 oz) cans sweetened condensed milk: Gives the filling its creamy, velvety texture and sweetness.
- 4 large egg yolks: Adds richness and helps thicken the filling while baking.
- ½ cup key lime juice (fresh or bottled): Infuses the bars with authentic tangy citrus brightness.
- 1 tablespoon key lime zest (optional): Intensifies lime aroma and adds a fresh, zesty punch.
- Whipped cream and extra lime zest for topping (optional): For a delightful finishing touch that complements the tartness perfectly.
How to Make Easy 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 or 9×9-inch baking pan with parchment paper, making sure to leave some overhang. This overhang will make it super easy to lift out your bars later. Combine the graham cracker crumbs, sugar, and melted butter in a bowl, mixing until everything is evenly moistened. Firmly press this mixture into the bottom of your prepared pan to form a smooth, even crust. Pop it into the oven for 8 to 10 minutes until it turns a light golden brown. This short bake ensures a crisp base that won’t get soggy once the filling is poured on.
Step 2: Whisk the Filling
While your crust is cooling slightly, whisk together the sweetened condensed milk, egg yolks, key lime juice, and optional lime zest in a separate bowl. The mixture should be smooth and glossy, promising sweet and tangy magic to come. This filling is where the creamy texture and citrus punch really shine, so be sure it’s well blended for even flavor throughout.
Step 3: Bake the Key Lime Filling
Pour the luscious filling evenly over your cooled crust, using a spatula if needed to smooth the top. Bake at 350°F for about 15 to 18 minutes. You want the filling to be set but still have a little jiggle in the center—that’s the signature silky texture that melts in your mouth. Let it cool completely at room temperature first, then move the pan to the fridge to chill for at least three hours or, better yet, overnight for best results.
Step 4: Slice and Serve
Once chilled, use the parchment paper overhang to lift out the slab of pie bars. Slice them carefully into squares, about 16 in total. If you want to take these bars from delicious to dazzling, top with whipped cream and sprinkle on additional lime zest for a pop of color and flavor that will have everyone asking for seconds.
How to Serve Easy Key Lime Pie Bars Recipe
Garnishes
Whipped cream is a classic companion to these bars, adding a light creaminess that balances the tart lime perfectly. Sprinkle a bit of fresh lime zest or even thin slices of lime on top for a pretty presentation and a burst of fresh aroma that invites smiles before the first bite.
Side Dishes
These bars shine beautifully on their own but can also be paired with refreshing sides like a scoop of vanilla ice cream or a simple mixed berry salad to enhance their bright citrus notes. Fresh mint leaves can add another layer of freshness on the side, creating an elegant dessert plate.
Creative Ways to Present
Try serving your key lime bars in mini jars for a fun, portable dessert or use cookie cutters to create festive shapes for parties. For a more decadent treat, drizzle some white chocolate over the tops or sprinkle a handful of toasted coconut flakes for a tropical twist that delights all the senses.
Make Ahead and Storage
Storing Leftovers
These key lime pie bars hold up wonderfully in the refrigerator for up to four days. Keep them in an airtight container to maintain their fresh texture and tangy flavor, making them a handy dessert ready whenever a citrus craving hits.
Freezing
If you want to keep these bars longer, they freeze beautifully. Wrap individual bars tightly with plastic wrap and then foil to protect them from freezer burn. When you’re ready, thaw them overnight in the refrigerator for a no-fuss, make-ahead dessert solution.
Reheating
Although these bars are best enjoyed cold, if you prefer them slightly warmer, let them sit at room temperature for 10 to 15 minutes before serving. Avoid microwaving, which can affect the texture of the creamy filling and the crisp crust.
FAQs
Can I use regular lime juice instead of key lime juice?
Absolutely! While key lime juice provides a unique and slightly more floral tartness, regular lime juice works just fine and will still give you that refreshing citrus flavor in the bars.
Is it necessary to bake the crust before adding the filling?
Yes, baking the crust first helps it set firmly and prevents it from becoming soggy once the filling is added. It also brings out the buttery flavor and adds a nice, subtle crunch.
Can I make these bars dairy-free or vegan?
This recipe relies on sweetened condensed milk and butter, which are dairy products, so it would require substitutions. There are dairy-free condensed milk alternatives and vegan butter you could try, but the texture might be slightly different.
Why do the bars need to chill overnight?
Chilling allows the filling to fully set and the flavors to meld beautifully. It also makes slicing easier and ensures a pleasant, firm texture when you bite in.
How can I add more lime flavor without making the bars too tart?
Using lime zest is a great way to amplify lime aroma without increasing acidity. You can also experiment with a bit more sweetened condensed milk to balance extra lime juice if you’re concerned about tartness.

This Easy Key Lime Pie Bars Recipe is a keeper in every sense—bright, creamy, and incredibly simple to make.
