These Key Lime Pie Bars are easy and delicious! With a zesty lime filling and a crunchy graham cracker crust, they make a perfect treat for any occasion.
I love how refreshing these bars are, especially on a warm day. Just watch out—they disappear fast when my friends come over! 😄
Key Ingredients & Substitutions
Graham Cracker Crumbs: These are a must for that classic crust. If you can’t find graham crackers, you can use digestive biscuits or crushed vanilla wafers as a substitute for similar crunch and flavor.
Sweetened Condensed Milk: This ingredient provides creaminess and sweetness. If you’re looking for a dairy-free option, try using coconut condensed milk, which adds a nice tropical twist!
Key Lime Juice: Freshly squeezed key lime juice gives the best flavor. If you can’t find key limes, regular limes are fine, but the taste will be a bit different. Just use the same amount.
Egg Yolks: They help to set the filling. If you want an egg-free version, you can use a flaxseed meal or chia seed gel (1 tablespoon mixed with 2.5 tablespoons water) as a substitute per yolk.
How Do I Make Sure My Filling Sets Properly?
Setting the filling is key to getting those perfect bars. Follow these tips to ensure success:
- Whisk the filling ingredients just until they’re combined to avoid introducing too much air. This helps prevent cracks.
- When you pour the filling over the crust, be sure it’s cooled completely. This keeps the crust firm and prevents sogginess.
- Watch the baking time closely! The filling should be set but have a slight jiggle—it will continue to firm up as it cools.

For The Crust:
- 1 1/2 cups graham cracker crumbs
- 1/2 cup sugar
- 1/2 cup unsalted butter, melted
For The Filling:
- 1 (14 oz) can sweetened condensed milk

- 3 large egg yolks
- Zest from 1 lime (for added flavor)
For The Topping:

How Much Time Will You Need?
This recipe will take about 15 minutes to prepare, plus 25-30 minutes of baking time, and finally a chilling time of at least 2 hours. So set aside approximately 2 hours and 45 minutes to enjoy your delicious Key Lime Pie Bars!
Step-by-Step Instructions:
1. Preheat the Oven:
First things first! Preheat your oven to 350°F (175°C). It’s important to get it nice and warm for the perfect bake.
2. Make the Crust:
In a medium bowl, mix together the graham cracker crumbs and sugar. Then, pour in the melted butter. Stir it up until everything is well combined and resembles wet sand. Now, take a 9×9 inch baking dish and firmly press this mixture into the bottom to form an even layer. Place it in the oven and bake for about 10 minutes, or until it’s golden brown. Once done, remove it and let it cool down a bit.
3. Prepare the Filling:
In another mixing bowl, whisk together the sweetened condensed milk, key lime juice, egg yolks, and lime zest. Mix it well until everything is nicely combined and smooth.
4. Bake the Filling:
Now it’s time to pour the key lime filling over the cooled graham cracker crust. Spread it out evenly. Bake it in the oven for an additional 15-20 minutes. It’s done when the filling is set but still has a slight jiggle in the center.
5. Cool and Chill:
After baking, remove the bars from the oven and let them cool at room temperature for a little while. Once they’ve cooled down, transfer them to the refrigerator and chill for at least 2 hours until they’re completely firm.
6. Serve and Enjoy!
Once chilled, take the bars out and cut them into squares. Serve them with a delicious dollop of whipped cream on top and a sprinkle of lime zest for that extra zing! Enjoy your scrumptious Key Lime Pie Bars!
Can I Substitute Regular Limes for Key Limes?
Yes, you can use regular limes instead of key limes, but the flavor will be slightly different. Key limes are smaller and have a more intense, tart flavor. If using regular limes, you may want to adjust the amount of sugar in the filling to balance the tartness.
How Do I Store Leftover Key Lime Pie Bars?
Store any leftovers in an airtight container in the refrigerator for up to 3 days. To maintain the texture of the filling, avoid leaving them out at room temperature for extended periods.
Can I Use Gluten-Free Graham Crackers?
Absolutely! You can substitute regular graham cracker crumbs with gluten-free graham crackers to make this recipe gluten-free. Just make sure to check the label to ensure they’re certified gluten-free.
What’s the Best Way to Ensure My Filling Sets Properly?
Make sure to bake the filling until it’s set but still slightly jiggly in the center. Keep an eye on it, as overbaking can lead to a rubbery texture. Letting the bars cool completely at room temperature before chilling in the fridge is key for achieving the right consistency.
