Ingredients
Main Ingredients for Key Lime Pie Bars
- 1 ½ cups graham cracker crumbs
- ½ cup unsweetened coconut flakes
- ½ cup granulated sugar
- ½ cup unsalted butter, melted
- 2 large eggs
- 1 can (14 oz) sweetened condensed milk
- ½ cup fresh key lime juice (or regular lime juice)
- Zest of 2 key limes
- ½ teaspoon vanilla extract
Key lime pie bars need a few key ingredients. First, graham cracker crumbs form the base. I use unsweetened coconut flakes to add flavor and texture. Sweetened condensed milk provides creaminess and sweetness. Fresh key lime juice gives that zesty kick. I also add lime zest for extra brightness.
Optional Toppings
- Whipped cream
- Lime slices
For a fun touch, I recommend whipped cream on top. A slice of lime adds color and flair. These toppings make the bars even more appealing. They enhance the flavors and make each bite more special. You can mix and match based on your taste!
Step-by-Step Instructions
Preparation Steps
- Preheat the oven to 350°F (175°C).
- In a bowl, mix 1 ½ cups of graham cracker crumbs, ½ cup of unsweetened coconut flakes, ½ cup of granulated sugar, and ½ cup of melted unsalted butter. Stir until all crumbs are coated.
Baking Instructions
- Press the mixture firmly into the bottom of a greased 9x9 inch baking dish to form a crust. Bake in the oven for about 10 minutes. The crust should turn lightly golden. Take it out and let it cool.
- In another bowl, whisk 2 large eggs until frothy. Add one can of sweetened condensed milk, ½ cup of fresh key lime juice, the zest of 2 key limes, and ½ teaspoon of vanilla extract. Whisk until smooth and combined.
- Pour this lime mixture evenly over the cooled crust. Bake for 15-18 minutes. The center should not jiggle too much when done.
Final Steps
- Let the bars cool to room temperature. Then, refrigerate for at least 2 hours to set completely.
- Once chilled, slice the bars into squares. Top with whipped cream and a slice of lime for garnish.
Tips & Tricks
Perfecting the Crust
To make a great crust, the right crumb consistency matters. You want fine crumbs to hold together well. Use a food processor to crush the graham crackers and coconut flakes into small pieces. If you use large chunks, your crust may not hold together.
When pressing the crust into the pan, use the bottom of a measuring cup. This helps create an even layer. Press firmly but gently to avoid breaking the crumbs. Make sure to cover the bottom fully for a nice base.
Enhancing Flavor
Fresh key lime juice makes a big difference. It adds brightness and a tart kick. Bottled juice can work, but it often lacks the same fresh taste. If you want to boost the flavor, add lime zest. The zest gives extra zing and aroma, making your bars even more delightful.
Baking Time
To tell if your bars are done, look for a slight jiggle in the center. They should not wobble too much. Overbaking will dry them out, so keep an eye on them. The bars should bake for 15 to 18 minutes. Check them around the 15-minute mark to avoid drying them out.
Pro Tips
- Use Fresh Limes: For the best flavor, always use fresh key limes or limes instead of bottled juice.
- Chill Thoroughly: Allow your bars to chill fully in the refrigerator for at least 2 hours to achieve the right texture and firmness.
- Customize the Crust: You can add crushed nuts or different flavored cookies to the crust for a unique twist.
- Perfectly Set Bars: Ensure the bars are set by checking that they jiggle slightly in the center but are not overly wobbly.
Variations
Flavor Variations
You can switch up the flavor of your key lime pie bars. One tasty option is coconut key lime pie bars. Just add unsweetened coconut flakes to the filling. This twist gives your bars a tropical taste. If you want the classic flavor, skip the coconut. The traditional key lime pie bars are still zesty and fresh.
Alternative Sweeteners
You might prefer to use natural sweeteners like honey or maple syrup. These can replace granulated sugar in the crust or filling. They add a nice touch of flavor too. If you are watching your carbs, try low-carb options for the crust. Almond flour or coconut flour works great. These alternatives keep your bars delicious while fitting your diet.
Serving Suggestions
When serving key lime pie bars, think about pairing them with fruit. Fresh berries or sliced mango add color and taste. You can also serve them with a scoop of sorbet. This makes a refreshing dessert. For gatherings, cut them into small squares. Arrange them on a platter with whipped cream and lime slices. This creates a beautiful and inviting spread.
Storage Info
Short-Term Storage
To keep your key lime pie bars fresh, use an airtight container. This prevents moisture from getting in. Store the bars in the fridge. The ideal temperature is below 40°F (4°C). This keeps them cool and tasty for a few days.
Long-Term Storage
You can freeze key lime pie bars for later enjoyment. First, cut the bars into squares. Wrap each square in plastic wrap or foil. Then, place them in a freezer bag. They can last up to three months in the freezer. To thaw, move them to the fridge overnight. Enjoy them chilled!
Shelf Life
In the fridge, these bars last about one week. Look for signs of spoilage before eating. If the bars have an off smell or a change in color, it’s best to throw them away. Fresh is always best!
FAQs
What is the difference between key lime pie and key lime pie bars?
Key lime pie is a classic dessert in a pie form. It has a flaky crust and creamy filling. Key lime pie bars, on the other hand, are more like dessert squares. They have a thicker crust and are easier to serve. You can cut them into neat squares. This makes them perfect for parties or picnics.
Can I make these bars vegan?
Yes, you can make vegan key lime pie bars! Substitute eggs with flax eggs. A flax egg is one tablespoon of ground flaxseed mixed with three tablespoons of water. Let it sit for a few minutes to thicken. Use coconut cream instead of sweetened condensed milk. This will keep the rich flavor and creamy texture.
How can I tell when the bars are done baking?
To check if the bars are done, look for a firm center. They should not jiggle too much. A slight wiggle is okay. The edges may also start to pull away from the pan. Let them cool completely and chill in the fridge for the best taste.
What can I substitute for key lime juice?
If you can't find key lime juice, regular lime juice works well. You can also use lemon juice for a different flavor. Just make sure to taste the filling and adjust the sugar. The goal is to keep that zesty and tangy flavor that makes these bars shine!
