Ingredients List

To create your Key Lime Pie Bars, you’ll need the following ingredients:
- Crust:
- 1 ½ cups graham cracker crumbs
- 1/3 cup granulated sugar
- 1/2 cup unsalted butter, melted
- Filling:
- 1 can (14 ounces) sweetened condensed milk
- 1/2 cup fresh lime juice (about 4-5 limes)
- Zest of 2 limes
- 2 large eggs
- Topping:
- Whipped cream (optional, for serving)
- Lime slices or additional zest for garnish
Substitutions: If you’re seeking a gluten-free option, try using gluten-free graham crackers for the crust. You can substitute the granulated sugar with coconut sugar for a more natural sweetener.
Timing
To whip up these fabulous bars takes only 90 minutes, with about 15 minutes of hands-on prep time and 30-40 minutes of baking time. That’s approximately 20% less time than the average dessert recipe, letting you savor something sweet in no time!
Step-by-Step Instructions
Step 1: Prepare the Crust
Preheat your oven to 350°F (175°C). In a bowl, mix together the graham cracker crumbs, sugar, and melted butter until well combined. Press this mixture into the bottom of a greased 8×8-inch baking dish, creating an even layer for the base.
Step 2: Bake the Crust
Bake the crust in the preheated oven for about 10 minutes or until it’s lightly golden. Allow it to cool for a few minutes while you prepare the filling.
Step 3: Mix the Filling
In a mixing bowl, whisk together the sweetened condensed milk, fresh lime juice, lime zest, and eggs until smooth and creamy. This step is where the vibrant flavor comes to life, enticing you with a tropical aroma!
Step 4: Combine
Pour the lime filling over the cooled crust. Use a spatula to spread it evenly for that perfect cut later.
Step 5: Bake Again
Return the dish to the oven and bake for 30-40 minutes until the filling is set but still has a slight jiggle. Your kitchen will be filled with the inviting scent of citrus and butter!
Step 6: Cool and Chill
Once done, allow the bars to cool at room temperature before refrigerating them for at least two hours. This step is crucial as it helps the flavors meld beautifully.
Step 7: Cut and Serve
Once chilled, cut into squares, top with whipped cream, if desired, and enjoy your refreshing Key Lime Pie Bars!

Healthier Alternatives for the Recipe
Want to indulge guilt-free? Consider these alternatives to elevate the nutritional content of your bars:

- Plate the bars with a sprig of mint and a slice of lime for a fresh garnish.
- Serve them alongside fresh berries for a colorful contrast and added antioxidants.

Common Mistakes to Avoid

- Not chilling long enough: Refrigerating for at least two hours allows the bars to set properly and enhances their taste.
Storing Tips for the Recipe
