Key Ingredients & Substitutions
Graham cracker crumbs: These give the crust its unique flavor and texture. If you don’t have graham crackers, you can substitute with crushed digestive biscuits or even vanilla wafer cookies for a twist.
Unsalted butter: This helps bind the crust ingredients together. You could use coconut oil or vegan butter if you’re looking for a dairy-free option.
Egg yolks: Four large egg yolks create a rich and creamy filling. For a vegan alternative, you can use silken tofu blended until smooth or unsweetened applesauce to keep the texture creamy.
Key lime juice: The star of the filling! If key limes aren’t available, regular limes work just fine. You can also use bottled key lime juice in a pinch, but fresh is always best for taste.
Heavy whipping cream: This is essential for a fluffy topping. If you’re looking for a lighter option, use coconut cream, or for a dairy-free alternative, opt for whipped coconut cream.
How Do You Get the Perfect Whipped Cream Topping?
Creating a fluffy whipped cream topping is a key part of this recipe. To get it just right, follow these steps:
- Start with cold heavy whipping cream. Chilling your mixing bowl too helps.
- Use a mixer on medium-high speed. This is where you’ll incorporate air into the cream.
- Slowly add powdered sugar while mixing. This helps sweeten and stabilize the cream.
- Keep whipping until you see stiff peaks form. Be careful not to overwhip, or it may turn into butter!
With these tips, you’ll achieve the perfect topping for your Key Lime Pie Bars, making them extra special. Enjoy the process!

How Much Time Will You Need?
This recipe takes about 20 minutes of prep time, plus 25-30 minutes of cooking time and at least 2 hours to chill in the fridge. In total, allow for about 2 ½ hours to make and set your Key Lime Pie Bars before serving.
Step-by-Step Instructions:
1. Preheat and Prepare:
Start by preheating your oven to 350°F (175°C). While it’s heating up, take an 8×8 inch baking dish and either grease it or line it with parchment paper. This will help you remove the bars later without any fuss!
2. Make The Crust:
In a medium bowl, combine the graham cracker crumbs, melted butter, and granulated sugar. Use a fork to mix everything together until it’s well combined. Once done, press this mixture firmly into the bottom of your prepared baking dish to create an even layer. Bake the crust in the oven for 10 minutes, then take it out and let it cool slightly.
3. Prepare The Filling:
In a separate bowl, whisk together the egg yolks and sweetened condensed milk until smooth. Then, stir in the fresh key lime juice and lime zest until everything is well mixed together. This will be your tart, zesty filling!
4. Bake The Filling:
Now, pour the tangy filling over the slightly cooled crust. Spread it out evenly using a spatula. Pop the dish back into the oven and bake for another 15-20 minutes, or until the filling is set. After baking, let it cool to room temperature, then refrigerate it for at least 2 hours to chill.
5. Make The Whipped Topping:
Once your bars are chilled, it’s time to whip up the topping. In a mixing bowl, beat the heavy whipping cream, powdered sugar, and vanilla extract on medium-high speed. Keep whipping until stiff peaks form, which should take just a few minutes.
6. Assemble and Serve:
Spread the whipped cream evenly over the chilled key lime filling. For an extra pop of color and flavor, sprinkle some lime zest on top. Finally, cut the bars into squares, serve chilled, and enjoy the refreshing taste of your homemade Key Lime Pie Bars!
Can I Use Regular Limes Instead of Key Limes?
Absolutely! While key limes provide a distinct tartness, regular limes can be used as a substitute. Just make sure to adjust the amount to taste, as regular limes can be a bit more acidic. You’ll still end up with a delicious pie!
Can I Make This Recipe Gluten-Free?
Yes, you can! Simply use gluten-free graham cracker crumbs or a gluten-free cookie alternative for the crust. Check the labels to ensure they’re certified gluten-free, and proceed with the recipe as usual.
How to Store Leftover Key Lime Pie Bars?
Store any leftovers in an airtight container in the refrigerator for up to 3 days. For best results, add the whipped cream topping just before serving to maintain its texture and prevent it from getting soggy.
Can I Freeze Key Lime Pie Bars?
Yes, you can freeze the bars! Before topping with whipped cream, wrap them tightly in plastic wrap and then aluminum foil. They can be frozen for up to 2 months. To serve, thaw in the fridge overnight and add fresh whipped cream before enjoying!
