These Key Lime Pie Bars are a refreshing treat that combines a zesty, creamy lime filling with a crumbly graham cracker crust. They are cool, tangy, and oh so delightful!
I love how easy these bars are to whip up. Perfect for summer picnics or just a sweet snack at home. Plus, they make you feel like you’re on a tropical vacation! 🌴
Key Ingredients & Substitutions
Graham Cracker Crumbs: Essential for the crust, these crumbs provide a lovely crumbly base. If you don’t have them, crushed digestive biscuits, vanilla wafers, or even crushed pretzels can work for a twist in flavor!
Sweetened Condensed Milk: This gives your filling its creamy texture and sweetness. If you’re looking for a dairy-free option, coconut cream or a plant-based condensed milk can be a great substitute.
Key Lime Juice: Fresh key limes are perfect for that tart kick. If you can’t find them, regular limes will do, but they’ll offer a slightly different flavor. Just make sure to adjust the sweetness if using a sweeter lime.
Heavy Whipping Cream: Use this for a rich topping. If you’re after a lighter option, whipped coconut cream is a tasty alternative that also offers a dairy-free option!
How Can I Get the Perfect Crust for My Key Lime Pie Bars?
The crust is the foundation of these delicious bars, and getting it right is key. Here’s how to ensure a perfectly golden crust:
- Mix the graham cracker crumbs with melted butter and sugar until it’s like wet sand.
- Press the mixture firmly into the baking dish to avoid a crumbly crust after baking.
- Bake until it’s lightly golden. This step adds flavor and helps it set up nicely.
Let it cool slightly before pouring in the filling—this helps the layers stay distinct!

How Much Time Will You Need?
This delightful recipe takes about 15 minutes of hands-on preparation, along with an additional 3 hours to chill in the fridge. You’ll have a little baking time too, making a total of around 3 hours and 30 minutes from start to finish. Perfect for a tasty treat!
Step-by-Step Instructions:
1. Preparing the Crust:
Start by preheating your oven to 350°F (175°C). Take an 8×8-inch baking dish and line it with parchment paper, making sure to leave some paper hanging over the edges for easy lifting later. In a medium bowl, mix the graham cracker crumbs, melted butter, and granulated sugar until everything is well combined. Press this mixture evenly into the bottom of your prepared baking dish. Bake it for about 10 minutes or until it’s lightly golden. After baking, take it out and let it cool slightly.
2. Making the Filling:
In another bowl, whisk together the sweetened condensed milk, sour cream, fresh key lime juice, lime zest, egg yolks, and salt until the mixture is smooth. Make sure everything is fully incorporated, so you get that delicious tangy flavor.
3. Pouring the Filling:
Carefully pour the filling over the cooled crust and spread it evenly. Bake in the oven for about 15-20 minutes. The filling should be set but still a little jiggly in the center. Once done, take it out and let it cool to room temperature. After cooling, pop it into the fridge for at least 3 hours, or until it’s nice and firm.
4. Preparing the Topping:
When you’re ready to serve, prepare the topping. In a mixing bowl, whip the heavy cream, powdered sugar, and vanilla extract together until you see stiff peaks form. This means your whipped cream will be nice and fluffy!
5. Final Touches:
Spread the whipped cream over the chilled key lime filling generously. For a little extra flair, garnish with some lime zest on top. Now, take a moment to admire your work!
6. Serving:
Using the parchment paper overhang, carefully lift the bars out of the baking dish. Slice them into squares, plate them up, and serve chilled. Enjoy your refreshing Key Lime Pie Bars with friends and family!
Can I Use Different Citrus Juice for the Filling?
Absolutely! While key limes give the bars their signature flavor, you can substitute regular lime juice or lemon juice if needed. Just keep in mind that the taste will change slightly, but it will still be delicious!
Can I Make the Crust in Advance?
Yes, you can prepare the crust a day ahead! Simply follow the instructions to bake and cool it, then cover it tightly with plastic wrap and store it at room temperature. Just make sure it’s completely cool before wrapping to prevent it from getting soggy.
How Should I Store Leftover Key Lime Pie Bars?
Store any leftovers in an airtight container in the refrigerator. They will keep well for up to 5 days, and are best enjoyed chilled. You can enjoy them cold or let them sit at room temperature for about 15 minutes before serving for a softer texture.
Can I Freeze Key Lime Pie Bars?
Yes, these bars freeze well! Once they are fully chilled, slice them into squares and wrap each piece tightly in plastic wrap, then place them in a freezer-safe container. They can be frozen for up to 2 months. Thaw them in the fridge before serving, and add fresh whipped cream just before serving for the best experience!
