Ingredients
To make delightful Key Lime Pie Bars, you need a few simple ingredients. Here’s the list:
- 1 cup graham cracker crumbs
- ¼ cup granulated sugar
- ½ cup unsalted butter, melted
- 2 large eggs
- 1 can (14 oz) sweetened condensed milk
- ½ cup key lime juice
- Zest of 2 limes
- Pinch of salt

These ingredients create a perfect mix of flavors and textures. The graham cracker crumbs form a sweet and crunchy crust. The sweetened condensed milk gives a creamy base.

Step-by-Step Instructions
Preheat the Oven
First, set your oven to 350°F (175°C). This temperature helps the bars bake evenly. Next, line an 8x8 inch baking dish with parchment paper. This makes it easy to lift the bars out later.
Prepare the Crust
In a medium bowl, mix together 1 cup of graham cracker crumbs and ¼ cup of granulated sugar. Then, add ½ cup of melted unsalted butter. Stir until the crumbs look wet. Press this mixture firmly into the bottom of your prepared dish to form a nice, even layer.
Bake the Crust
Now, place the crust in your preheated oven. Bake it for about 8 to 10 minutes. Look for a light golden color on the crust. Once it’s ready, take it out and let it cool slightly.
Make the Filling
In a large bowl, whisk together 2 large eggs, 1 can (14 oz) of sweetened condensed milk, and ½ cup of key lime juice. Add the zest of 2 limes and a pinch of salt. Mix until it's smooth. This filling is what makes the bars so zesty and tasty.
Combine and Bake
Pour the filling over your cooled crust. Make sure to spread it out evenly. Then, put the dish back in the oven. Bake for 15 to 18 minutes. The filling should be set but still have a slight jiggle in the center.
Cooling and Serving
After baking, remove the dish from the oven. Let it cool down at room temperature for a bit. Then, place it in the fridge for at least 2 hours. This chilling time helps the bars firm up. Once chilled, lift the pie bars out using the parchment paper. Cut them into squares. You can top them with whipped cream and lime slices for a fun touch.
Tips & Tricks
Perfecting the Filling
To get the best filling, focus on a few key points. First, use fresh key lime juice for a bright flavor. If you can’t find it, bottled juice works too, but fresh is best. Whisk the eggs and sweetened condensed milk together well. This helps mix air into the filling, giving it a light texture. The lime zest adds a nice touch, so don’t skip it. When you bake, check for a slight jiggle in the center. This means it’s perfect!
Crust Variations
If you want to mix it up, try different crusts. You can use almond flour for a nutty twist. A chocolate cookie crust is great too. Just crush your cookies and mix them with butter, like you do with graham crackers. You can even try a shortbread crust for a rich flavor. Each crust brings a new taste to your pie bars.
Serving Suggestions
Serving Key Lime Pie Bars can be fun and creative. You can top them with whipped cream to add sweetness. A slice of lime on each bar makes for a pretty touch. For extra flair, dust the bars with powdered sugar. Arrange them on a colorful platter for a great look. Try serving them with a scoop of vanilla ice cream for a treat!
Pro Tips
- Chill for Best Results: Allow the key lime pie bars to chill completely in the refrigerator for at least 2 hours. This helps the flavors meld and ensures a firmer texture.
- Use Fresh Juice: Opt for freshly squeezed key lime juice instead of bottled for a brighter, more authentic flavor in your filling.
- Perfectly Set Filling: Keep an eye on the bars while baking; they should be set around the edges with a slight jiggle in the center when done.
- Garnish Wisely: Top with freshly whipped cream and a slice of lime for an appealing presentation and added flavor contrast.
Variations
Different Citrus Options
You can change the flavor by using different citrus fruits. If you want a twist, try lemons. Lemon bars have a bright and tangy taste. Oranges can also work well. They add a sweet and zesty touch. Each option gives you a new experience. You can keep the same method from the key lime recipe but switch the juice.
Gluten-Free Options
For those who need gluten-free treats, you have choices. You can use gluten-free graham cracker crumbs. There are many brands available now. Almond flour or ground oats can also serve as a crust. Just mix them with sugar and melted butter. Press firmly into the dish like you would with regular crumbs.
Vegan Adaptations
Want to make your bars vegan? It is easy! Instead of eggs, use flaxseed meal. Mix one tablespoon of flaxseed meal with three tablespoons of water. Let it sit until it thickens. Swap the sweetened condensed milk with coconut cream or a dairy-free version. These changes keep the bars creamy and delicious without using animal products.
Storage Info
Best Practices for Storing
To keep your leftover Key Lime Pie Bars fresh, place them in an airtight container. You can also cover them with plastic wrap. Store the bars in the refrigerator. This will help keep their tangy flavor and smooth texture. Make sure they are completely cool before storing. This prevents condensation from forming inside the container.
Freezing Tips
If you want to freeze your Key Lime Pie Bars, follow these steps:
- First, let the bars cool completely.
- Next, cut them into squares.
- Wrap each square tightly in plastic wrap.
- Place the wrapped bars in a freezer bag.
- Label the bag with the date and type.
You can freeze the bars for up to three months. When you're ready to enjoy them, thaw in the fridge for a few hours before serving.
Shelf Life
Key Lime Pie Bars can last in the fridge for about five days. After that, they may lose their taste and texture. Always check for any signs of spoilage before eating. If they look or smell off, it's best to discard them. Keeping them stored properly will help you enjoy these treats longer.
FAQs
How long do Key Lime Pie Bars need to chill?
Key Lime Pie Bars need to chill for at least 2 hours. This time helps the filling set and improves the flavor. If you can wait longer, chilling them overnight works great too. The longer they chill, the better they taste.
Can I use bottled key lime juice?
Yes, you can use bottled key lime juice. It saves time and is easy to find. However, fresh juice tastes better. Bottled juice may lack the bright flavor of fresh limes. If you want true taste, use freshly squeezed juice.
What is the best way to cut the bars?
To cut the bars cleanly, use a sharp knife. Dip the knife in hot water, then wipe it dry. This method helps you get neat squares. Make sure to cut them after they are fully chilled. This way, they will hold their shape well.
