– 2 tablespoons sugar
– pinch salt
– 6 tablespoons unsalted butter (melted)
– 6 ounces cream cheese (room temperature)
– 1 (14-ounce) can sweetened condensed milk
– 4 egg yolks
– 1 tablespoon lime zest
– ½ cup key lime juice (or regular lime juice)
– ½ teaspoon vanilla extract
How to Make Key Lime Pie Bars
Step 1: Preheat the Oven
Preheat your oven to 350°F. Line a 9×9-inch pan with aluminum foil or parchment paper, making sure it hangs over the edges for easy removal later.
Step 2: Prepare the Crust
- In a food processor or large Ziploc bag, crush the graham crackers until fine crumbs form.
- In a medium mixing bowl, combine the crumbs with sugar, salt, and melted butter. Mix until well combined.
- Press the mixture evenly into the bottom of the lined pan. Bake in the preheated oven for 10 minutes.
Step 3: Make the Filling
While the crust bakes, prepare the filling:
In a large mixing bowl with a hand mixer or using a stand mixer, beat the cream cheese until smooth and creamy.
Gradually add in the sweetened condensed milk and mix until fully combined.
Incorporate egg yolks one at a time, ensuring each is mixed well before adding the next. Then add lime zest, juice, and vanilla extract. Mix until smooth.
Step 4: Bake Again
Pour the filling over your hot baked crust. Return it to the oven and bake for 15-18 minutes until set; avoid browning on top.
Step 5: Chill and Serve
Remove from oven and let cool at room temperature before chilling in the refrigerator for 2-4 hours. When ready to serve, cut into squares and enjoy! Store leftovers in an airtight container in the refrigerator for up to 5 days.

Top with Fresh Whipped Cream
- A dollop of freshly whipped cream adds a rich and creamy texture that beautifully complements the tartness of the key lime filling.
Garnish with Lime Slices
- Add bright slices of fresh lime on top for an eye-catching presentation and an extra burst of citrus flavor.
Serve with Coconut Flakes

How to Perfect Key Lime Pie Bars
Achieving the perfect key lime pie bars requires attention to detail. Here are some tips to ensure your dessert turns out amazing every time.
- Use Fresh Juice – Whenever possible, use fresh key lime juice instead of bottled juice for a brighter, more authentic flavor.
- Soften Cream Cheese – Make sure your cream cheese is at room temperature before mixing; this prevents lumps and ensures a smooth filling.
- Don’t Overbake – Bake just until set; overbaking can lead to cracks. The filling should slightly jiggle when you take it out.
- Chill Thoroughly – Letting the bars chill for several hours helps them set properly and enhances their flavors.
- Cut Cleanly – Use a sharp knife dipped in hot water to cut clean lines for a beautiful presentation.
- Store Properly – Keep any leftovers in an airtight container in the fridge to maintain freshness for up to 5 days.
Best Side Dishes for Key Lime Pie Bars
Pairing side dishes with key lime pie bars can enhance your dining experience. Here are some tasty options that complement the flavors beautifully.
- Grilled Pineapple – The sweetness of grilled pineapple contrasts nicely with tartness, making it a refreshing addition.
- Coconut Rice – Light and aromatic coconut rice adds a subtle sweetness that harmonizes with the flavors of the key lime pie bars.
- Tropical Fruit Salad – A mix of mangoes, papayas, and kiwi creates a vibrant side dish bursting with flavor that pairs well with dessert.
- Minted Pea Salad – This refreshing salad offers bright notes from mint and peas, balancing out the richness of the bars.
- Spicy Shrimp Skewers – The heat from spicy shrimp skewers provides an exciting contrast to the sweet and tangy dessert.
- Avocado Toast – Simple avocado toast topped with sea salt makes for a savory bite that complements sweet treats perfectly.
Common Mistakes to Avoid
Making key lime pie bars can be simple, but there are common pitfalls to watch out for.
- Using stale graham crackers: Fresh graham crackers yield a better crust. Always check the expiration date.
- Not chilling long enough: For the best texture, chill the bars for 2-4 hours. Rushing this step can result in a runny filling.
- Overmixing the filling: Mix just until combined to avoid incorporating too much air, which can create cracks.
- Skipping the lime zest: Lime zest adds essential flavor. Don’t skip it; instead, use a microplane for fine zesting.
- Not measuring ingredients accurately: Use proper measuring cups and spoons. Accurate measurements lead to consistent results.

Storage & Reheating Instructions
Refrigerator Storage
- Store in an airtight container for up to 5 days.
- Keep the bars separated with parchment paper if stacking.
