How to Make Key Lime Pie Bars

Step 1: Prepare the Crust

Combine graham cracker crumbs, sugar, and melted butter in a bowl until the mixture resembles wet sand. Press this evenly into a greased 9×9-inch baking pan to form the base. Bake for about 10 minutes at 350°F (175°C) until golden and set. Let it cool slightly before adding the filling.

Step 2: Mix the Filling

Whisk together egg yolks and sugar until smooth and pale. Stir in the sweetened condensed milk, fresh Key lime juice, and a pinch of salt. Mix until the filling thickens slightly and is thoroughly combined.

Step 3: Bake the Bars

Pour the filling over the warm crust and spread evenly. Bake the pie bars at 350°F (175°C) again for about 15 minutes or until the edges barely begin to brown and the filling is set but still a bit jiggly in the center.

Step 4: Cool and Chill

Remove from the oven and allow the bars to cool to room temperature before chilling in the refrigerator for at least two hours. Chilling helps the filling to firm up for perfect slicing.

Step 5: Slice and Serve

Use a sharp knife to cut the bars into squares. For cleaner cuts, dip the knife in hot water and wipe between slices. Garnish with whipped cream and lime zest as desired, then dig in!

Pro Tips for Making Key Lime Pie Bars

• Use Fresh Key Limes: Fresh juice has the brightest flavor, but bottled lime juice can be a good substitute if necessary.
• Press Crust Firmly: Packing the crust tightly ensures it holds together and doesn’t crumble when cutting.
• Don’t Overbake: Slightly underbaking the filling keeps it creamy and perfectly smooth instead of dry.
• Chill Thoroughly: Refrigeration is key to getting clean slices and enhancing the flavors.
• Experiment with Texture: Try adding a sprinkle of coarse salt on top for a sweet-salty contrast.

How to Serve Key Lime Pie Bars

Garnishes

Whipped cream is a classic topping that adds lightness and balances tartness. Fresh lime zest sprinkled on top gives bursts of citrus aroma and a visual pop. For a festive feel, add a few fresh berries or mint leaves.

Side Dishes

These bars pair beautifully with a cup of chilled iced tea or a scoop of vanilla ice cream to heighten the creaminess. For a tropical vibe, serve alongside fresh fruit salad or a mango salsa.

Creative Ways to Present

Try serving the Key Lime Pie Bars in mini mason jars for individual portions or cut into bite-sized squares on a dessert platter for parties. Adding edible flowers or drizzles of lime glaze can elevate their charm for special occasions.

Make Ahead and Storage

Storing Leftovers

Store leftover Key Lime Pie Bars covered in an airtight container in the refrigerator for up to 4 days to maintain freshness and texture.

Freezing

Wrap each bar individually in plastic wrap and place in a freezer-safe container. Freeze for up to one month, then thaw overnight in the fridge before serving.

Reheating

Refrigerate leftovers rather than reheating, as warming may affect the creamy filling’s texture. Serve cold or at room temperature for the best experience.

FAQs

Can I use regular lime juice instead of Key lime?

Yes, regular lime juice works, but Key limes have a slightly more floral and tart flavor that makes the bars truly authentic.

Is it necessary to bake these bars twice?

Baking the crust first prevents sogginess, and baking again after adding the filling ensures the custard sets perfectly.

Can these bars be made gluten-free?

Absolutely! Substitute graham crackers with gluten-free alternatives or crushed gluten-free cookies for a safe and delicious crust.

How long do Key Lime Pie Bars last in the fridge?

Stored properly, they stay fresh and tasty for up to 4 days refrigerated.

Can I double the recipe for a larger batch?

Yes, doubling is easy; just use a larger baking dish and adjust baking time as needed, watching closely for doneness.
