Ingredients for Key Lime Pie Bars
Complete Ingredient List with Measurements
- 1 cup graham cracker crumbs
- 1/4 cup sugar
- 1/2 cup unsalted butter, melted
- 1 can (14 oz) sweetened condensed milk
- 1/2 cup key lime juice (fresh or bottled)
- 3 large egg yolks
- Zest of 1 lime
- Whipped cream (for serving)
Each ingredient plays a crucial role in building the flavor profile of these Key Lime Pie Bars. The buttery crust supports the rich filling, while the lime juice and zest give that iconic tangy taste we crave.
Substitutes and Alternatives
If you’re looking for alternatives due to dietary needs or preferences, there are several options. For example, you can use gluten-free graham crackers instead of traditional ones if you’re catering to a gluten intolerance. Coconut oil can replace unsalted butter for a dairy-free option while maintaining that rich flavor you’d expect. Moreover, if key limes aren’t available, standard limes can do the trick, though they may alter the taste slightly.
How to Make Key Lime Pie Bars – Step-by-Step Directions
Step 1 – Prepare Ingredients
Before you start, gather all your ingredients. Ensure your butter is melted and your limes are juiced and zested for efficiency. Preheating the oven to 350°F (175°C) will prepare your space for baking.
Step 2 – Cook the Base
In a mixing bowl, combine graham cracker crumbs, sugar, and melted butter. Stir until the mixture is evenly moistened. Press this mixture firmly into the bottom of a greased 8×8 inch baking dish. This step helps form a solid crust for your bars.
Step 3 – Create the Filling
In a separate bowl, whisk together the sweetened condensed milk, key lime juice, egg yolks, and lime zest. Mix until smooth and thoroughly combined. This will create the rich and tangy filling that characterizes these Key Lime Pie Bars.
Step 4 – Assemble the Dish
Pour the key lime filling over the prepared crust. Spread it evenly to ensure every bite is delicious. The filling should be smooth and creamy, covering every bit of the crust.
Step 5 – Bake
Place the baking dish in the preheated oven. Bake for 15-20 minutes, or until the center is set but still slightly jiggly. This means your bars will be soft and luscious after cooling.
Step 6 – Cool Down
Once baked, remove the dish from the oven. Allow it to cool at room temperature for about 30 minutes. This cooling step is crucial for the flavors to settle.
Step 7 – Refrigerate
After cooling, place the pan in the refrigerator for at least two hours. Chilling allows the bars to firm up properly, making them easier to cut and serve.
Step 8 – Cut into Bars
Once chilled, use a sharp knife to cut the dessert into squares or rectangles. A clean cut will enhance the presentation, making it more appealing for serving.
Step 9 – Serve
Before serving, top your Key Lime Pie Bars with whipped cream. This adds a delightful creaminess that complements the tartness of the lime.
Step 10 – Enjoy
Serve these bars at your next gathering or keep them for a tasty treat at home. Each bite will be a burst of flavor.

How to Store Key Lime Pie Bars Properly
Best Storage Practices
To keep your Key Lime Pie Bars fresh, store them in the refrigerator. Use an airtight container to protect them from absorbing odors. Bringing them in contact with foil or plastic wrap can also help maintain their quality.
For longer storage, you can freeze the bars. Just wrap them tightly in plastic wrap, then place them in a freezer-safe container. They will keep well for up to three months in the freezer.
Reheating and Freezing Tips
If you choose to freeze your Key Lime Pie Bars, thaw them in the refrigerator overnight or at room temperature for a couple of hours before serving. Avoid microwaving them, as this can change the texture of the filling.
