How to Make Key Lime Pie Bars
Step 1: Preheat the Oven
Preheat your oven to 350°F (175°C). This ensures that your crust bakes evenly.
Step 2: Prepare the Crust
- In a food processor, combine the finely ground vanilla wafer cookies, melted butter, and light brown sugar.
- Pulse until well mixed.
- Press this mixture firmly into the bottom of your greased baking dish to create an even layer.
Step 3: Bake the Crust
Bake in your preheated oven for about 10 minutes or until lightly golden. Remove from oven and allow it to cool slightly.
Step 4: Make the Filling
- In a mixing bowl, whisk together the lime zest, egg yolks, and sweetened condensed milk until smooth.
- Gradually add in freshly squeezed lime juice while continuing to whisk until fully combined.
Step 5: Pour Filling Over Crust
Pour the filling mixture over your cooled crust. Spread it evenly using a spatula.
Step 6: Bake Again
Return to the oven and bake for another 15-20 minutes. The filling should be set but still slightly jiggly in the center.
Step 7: Cool & Chill
Allow bars to cool at room temperature before refrigerating for at least two hours or until fully chilled.
Step 8: Prepare Whipped Cream Topping
- In a separate bowl, beat heavy whipping cream with powdered sugar until soft peaks form.
- Spread this whipped cream over your chilled key lime pie bars before serving.

Chill and Serve
- Serve the bars straight from the fridge for the best flavor. The coolness complements their tangy taste perfectly.
Garnish with Whipped Cream

How to Perfect Key Lime Pie Bars
Perfecting key lime pie bars is all about attention to detail. Here are some tips to ensure your bars turn out just right.
- Use fresh limes: Freshly squeezed lime juice gives the best flavor compared to bottled juice, enhancing the tartness.
- Don’t overbake: Keep an eye on your baking time; the center should still have a slight jiggle when you take it out of the oven.
- Cool completely: Allow the bars to cool at room temperature before chilling in the fridge. This helps set their texture perfectly.
- Chill overnight: For optimal flavor and firmness, let your bars chill overnight before slicing and serving.
- Cut with care: Use a sharp knife warmed under hot water for clean slices, which makes for better presentation.
- Store properly: Keep any leftovers in an airtight container in the fridge to maintain freshness.

Common Mistakes to Avoid

- Not using fresh lime juice: Bottled juice lacks flavor. Always use freshly squeezed juice for the best taste.
- Skipping the chilling time: These bars need time to set. Allow them to chill in the fridge for several hours before serving.
