Key Ingredients & Substitutions
Graham Cracker Crumbs: This is the base of your crust. If you don’t have graham crackers, try using crushed digestive biscuits or even Oreo cookies for a twist on flavor. Just adjust the sugar accordingly!
Sweetened Condensed Milk: This is key for the creamy texture. If you’re looking for a dairy-free option, you can use coconut milk combined with a little sugar to mimic the sweetness.
Key Lime Juice: Fresh key limes create the best flavor, but if you can’t find them, regular limes work too. Just remember that key limes are usually sweeter and more aromatic than their larger cousins.
Sour Cream: This adds a nice tanginess. For a lighter version, you can use Greek yogurt instead. It will give you a similar taste with added protein!
How Do I Get the Perfect Crust?
Making the crust is super simple, but you need to press it firmly to avoid it falling apart. Here’s how:
- Mix the graham cracker crumbs with melted butter, sugar, and salt until combined.
- Use the bottom of a measuring cup or your hands to press it evenly into the pan. Make sure it’s packed well!
- Don’t forget to bake it first; this helps set the crust and adds a nice crunch.
What’s the Secret to a Creamy Filling?
To achieve the smooth filling, follow these steps:
- Make sure your eggs are at room temperature; they blend better.
- Whisk the sweetened condensed milk, sour cream, lime juice, zest, and eggs thoroughly until there are no lumps.
- Pour it carefully onto the crust to avoid mixing the layers.
How Do I Get Stiff Peaks in My Whipped Cream?
Creating the perfect whipped cream is all about technique:
- Use chilled heavy cream and a chilled mixing bowl for better volume.
- Start mixing at medium speed and gradually increase; add the powdered sugar when it thickens!
- Watch it closely; once stiff peaks form, stop! Over-whipping can turn it into butter.
With these tips, you’re all set to impress with your Key Lime Pie Bars! Enjoy making them!
How to Make Key Lime Pie Bars?
Ingredients You’ll Need:
For The Crust:
- 1 ½ cups graham cracker crumbs
- ½ cup unsalted butter, melted
- ¼ cup granulated sugar
- ¼ teaspoon salt
For The Filling:
- 1 can (14 ounces) sweetened condensed milk
- ½ cup sour cream
- ½ cup fresh key lime juice (about 4-6 key limes)
- Zest of 2 key limes
- 3 large eggs
For The Topping:

How Much Time Will You Need?
This recipe will take about 15 minutes to prepare, plus 10 minutes for baking the crust and another 15-20 minutes for the filling. After baking, you’ll need to chill the bars for at least 3 hours before serving. So, in total, you’ll be looking at around 4 hours, including cooling and chilling time.
Step-by-Step Instructions:
1. Prepare the Crust:
First, preheat your oven to 350°F (175°C). Take an 8×8 inch square baking pan, grease it, and line it with parchment paper, leaving some extra paper hanging over the sides. This will help you lift the bars out later.
In a medium bowl, mix the graham cracker crumbs, melted butter, granulated sugar, and salt together until everything is well combined. Press this mixture firmly into the bottom of your prepared baking pan to create an even crust. Bake it in the oven for about 10 minutes, then take it out and let it cool slightly.
2. Make the Filling:
While the crust is cooling, grab a large mixing bowl to prepare the filling. Whisk together the sweetened condensed milk, sour cream, key lime juice, key lime zest, and eggs until the mixture is smooth and blended nicely.
Pour this filling over your cooled crust, making sure to spread it evenly. Bake again for an additional 15-20 minutes, or until the filling is set but still has a slight jiggle in the center.
3. Chill and Top:
After the filling is done baking, remove the pan from the oven and let it cool to room temperature. Once it’s cooled, put it in the refrigerator for at least 3 hours to chill thoroughly.
When you’re ready to serve, whip the heavy cream in a mixing bowl with the powdered sugar until stiff peaks form. Spread this delicious whipped cream over the chilled bars and sprinkle on some extra lime zest for a pretty touch.
To serve, carefully lift the bars out of the pan using the overhanging parchment paper. Cut them into nice squares and enjoy your tasty Key Lime Pie Bars!
Can I Use Regular Limes Instead of Key Limes?
Absolutely! While key limes have a unique tart flavor, you can substitute regular limes in the same amount. Just keep in mind that the taste will be slightly different—less tart, but still delicious!
How to Store Leftovers?
Store any leftover Key Lime Pie Bars in an airtight container in the refrigerator for up to 4 days. If you’re layering them, place parchment paper between layers to prevent sticking.
Can I Make These Bars Gluten-Free?
Yes, you can! Simply use gluten-free graham cracker crumbs for the crust. Check the packaging to ensure there are no hidden gluten ingredients, and you’ll have a delicious gluten-free treat!
What If I Don’t Have Heavy Cream for Topping?
No problem! You can substitute with whipped toppings or even use a mixture of Greek yogurt and a bit of sugar for a lighter version. Just be sure to whip it until soft peaks form if you’re using yogurt!
