Kitchen Tools You’ll Need
- Baking dish
- Mixing bowls
- Whisk
- Measuring cups
- Measuring spoons
- Rubber spatula
Ingredients
- 1 ½ cups graham cracker crumbs (provides structure and texture)
- ½ cup unsalted butter, melted (adds richness and moisture)
- ⅓ cup granulated sugar (sweetens and enhances flavors)
- 2 large eggs (binds ingredients and creates structure)
- 1 can (14 oz) sweetened condensed milk (adds creaminess and sweetness)

- Zest of 2 limes (adds aromatic flavor)
- ¼ teaspoon salt (enhances overall taste)
How to Make Key Lime Pie Bars
Step 1. Begin by preheating your oven, ensuring the temperature is set before you start mixing ingredients. This helps create a consistent baking environment, essential for your bars to set properly.
Step 2. In a mixing bowl, combine the graham cracker crumbs, melted butter, and granulated sugar. Stir until the mixture resembles wet sand. The crumbs should hold together when squeezed, creating a solid base for your pie bars.
Step 3. Press this crumb mixture into the bottom of a prepared baking dish. Ensure it’s evenly distributed and firmly packed, which will give your bars a sturdy crust that holds up nicely after baking.
Step 4. Bake the crust in the preheated oven until it begins to brown slightly around the edges. This indicates that the crust is set and developing flavor, which creates a solid base for the filling.
Step 5. While the crust cools, combine the eggs, sweetened condensed milk, lime juice, lime zest, and salt in a clean bowl. Whisk everything together until smooth. A consistent mixture without lumps is key to achieving a creamy filling.
Step 6. Pour the lime filling over the cooled crust. Spread it evenly using a rubber spatula, ensuring it covers the crust completely. This step sets you up for a balanced taste in every bite of your Key Lime Pie Bars.
Step 7. Return the baking dish to the oven and bake until the filling is just set, which may take a little longer than the crust. Look for a slight jiggle in the center when you gently shake the pan—this means it’s ready to come out.
Step 8. Once baked, allow the bars to cool at room temperature before refrigerating. Cooling helps the filling firm up further, resulting in cleaner slices when you cut them.
Step 9. Finally, chill the bars in the refrigerator for a couple of hours. This step enhances their texture and allows the flavors to meld together, making every bite a delightful experience.
Serving Suggestions

Pro Tips for Best Results
- Make sure your butter is fully melted, but not hot, to avoid overcooking the crumb mixture.
- Use freshly squeezed lime juice for the best flavor—bottled options often lack that vibrant punch.
- Allow the filling to cool before refrigerating for better texture and easier slicing later.
- For even squares, use a sharp knife and clean cuts between each slice.
- Letting the bars chill overnight can enhance flavor and texture, making them even more delightful.
- Store any leftovers tightly covered to maintain freshness.
Common Mistakes to Avoid
- Not pressing the crust firmly enough: If the crust isn’t compact, it may crumble when cutting the bars. Make sure to use the back of a measuring cup or a similar tool to pack it down well.
- Overbaking the filling: If the filling is cooked too long, it can become rubbery. Watch for that slight jiggle to ensure it’s just right.
- Using bottled lime juice: This can result in a less flavorful outcome. Freshly squeezed lime juice provides the vibrant taste these bars shine with.
- Skipping the chilling step: Not allowing them to set properly can lead to messy slices and a softer texture. Be patient, as this makes a difference.
- Using cold ingredients: Cold eggs and condensed milk may not blend as smoothly. Allow them to come to room temperature for a consistent mixture.
- Not measuring accurately: Baking is a science, so be precise with measurements to ensure the right balance of flavors and textures.
Variations & Substitutions
For a different take, consider adding a layer of whipped cream on top after chilling for an extra creamy finish. You might also sprinkle some toasted coconut for added texture and flavor. If you prefer a less sweet option, reduce the sugar in the filling slightly to balance the tartness of the lime juice.
Storage & Reheating
Store any leftover bars at room temperature for up to a few hours or refrigerate them in an airtight container for up to a week. If you’d like to keep them longer, they can be frozen for up to three months. To thaw, simply leave them in the fridge overnight. Avoid reheating in the oven, as this can alter the texture; they’re best enjoyed chilled.
