Key Lime Pie Bars
Serves: 16
Cook Time: 3hr 53mins
These Key Lime Pie Bars are the perfect blend of tangy and sweet, with a buttery crust that crumbles just right.

For the Crust:

2 Cups Graham Cracker Crumbs

5 Tbsp Unsalted Butter, Melted

2 Tbsp Light Brown Sugar

For the Filling:

1 Tbsp Lime Zest

5 Large Egg Yolks

22 Oz Sweetened Condensed Milk 

1 Cup Freshly Squeezed Lime Juice

For the Topping:

1 Cup Heavy Whipping Cream

2 Tbsp Confectioner Sugar


1. Preheat Your Oven 

Preheat your oven to 350°F. Then, line a 9x9-inch baking pan with parchment paper, leaving some overhang for easy removal.

2. Make the Crust 

In a medium bowl, combine graham cracker crumbs, sugar, and melted butter. Mix until well combined, and press the mixture firmly into the bottom of the prepared pan. 
Bake for 10 minutes until lightly golden, then let it cool slightly.

3. Prepare the Filling

Using a stand mixer, whisk the egg yolks and key lime zest until the mixture has thickened. Then, add the key lime juice and sweetened condensed milk. Continue to whisk until the mixture is smooth and well combined.

4. Bake the Bars 

Pour the filling over the baked crust, spreading it evenly. Bake for 15-20 minutes until the filling is set, but still wiggles as a whole when you shake the pan. 
Let it cool completely at room temperature, then refrigerate for at least 3 hours to set.

5. Whip the Topping 

In a large bowl, whip the heavy cream and powdered sugar until stiff peaks form. Spread the whipped cream over the chilled bars, and refrigerate for 20 minutes, or until ready to serve. 

6. Serve 

Lift the bars out of the pan using the parchment overhang. Cut into squares and enjoy! Garnish with extra lime zest if desired.


1. Use Fresh Key Lime Juice

Fresh key lime juice gives the best flavor, but bottled key lime juice works in a pinch.

2. Make Ahead

These bars can be made a day ahead and stored in the fridge. Perfect for prepping before a party or gathering!

3. Add Extra Crunch

Add a sprinkle of graham cracker crumbs on top of the whipped cream for a satisfying crunch.
