Lime Pie Bars Ingredients For the Crust • Graham Crackers – Provide the crust’s structure and crunch; substitute with gluten-free graham crackers for a gluten-free option. • Butter – Adds richness and helps bind the crust ingredients; use vegan butter for a dairy-free alternative. For the Filling • Key Lime Juice – The primary source of tartness; fresh key limes are best, but regular limes can be used in a pinch. • Zest of Key Limes – Enhances flavor with aromatic citrus notes; ensure to zest before juicing the limes. • Sweetened Condensed Milk – Contributes sweetness and creaminess to the filling; a non-dairy version can be used. • Vanilla Extract – Adds depth to the flavor; opt for pure vanilla for the best taste. • Sour Cream or Yogurt – Provides creaminess and balances the acidity; can replace with equal parts cream cheese for a different texture. • Egg Yolks – Helps set the filling; for a vegan option, substitute with additional yogurt, but the bars may not be as firm. For the Topping • Heavy Cream – Used for the topping, whipped to stiff peaks for a light and airy finish; coconut cream can be used for a dairy-free topping. Step‑by‑Step Instructions for Lime Pie Bars Step 1: Preheat and Prepare Preheat your oven to 350°F (175°C). Line a 9×9″ baking pan with parchment paper, allowing some overhang for easy removal later. Gather your equipment: a food processor, mixing bowl, and whisk. This is essential for creating the delicious lime pie bars with a perfect crust. Step 2: Make the Crust In a food processor, pulse graham crackers until finely crushed. Melt butter and mix it into the crumbs until combined. Press the buttery mixture firmly and evenly into the bottom of your prepared pan. Bake for 8-10 minutes or until the crust is golden brown and fragrant, then set aside to cool slightly. Step 3: Mix the Filling While the crust cools, zest and juice your key limes, aiming for vibrant flavor. In a mixing bowl, combine the key lime juice, zest, sweetened condensed milk, vanilla extract, and sour cream. Whisk until smooth and creamy, ensuring each ingredient is well integrated for the luscious filling of your lime pie bars. Step 4: Add Egg Yolks Add the egg yolks to the key lime mixture, whisking until well blended. Taste the mixture and adjust any sweetness if desired, ensuring a balanced flavor profile. Pour this vibrant filling over your cooled crust in the baking pan, smoothing it out with a spatula for an even layer across these delightful lime pie bars. Step 5: Bake the Bars Bake in the preheated oven for 15-20 minutes, or until the center is set but still slightly jiggly. The edges should look firm while the center has a gentle wobble, ensuring that the filling will firm up nicely as it cools. Remove from the oven and let the bars cool completely at room temperature. Step 6: Chill to Set Once cooled, cover the baking pan with plastic wrap and refrigerate the lime pie bars for at least 4 hours, or overnight if possible. This chilling ensures that the flavors meld beautifully and the texture becomes the perfect setting for your creamy dessert. Step 7: Whip the Cream When ready to serve, whip heavy cream in a chilled bowl until stiff peaks form. This will create a light and airy topping for your lime pie bars. Spread the whipped cream evenly over the top or use a piping bag for an elegant finish on this refreshing dessert. Step 8: Slice and Serve Carefully slice the chilled lime pie bars using a sharp knife, cleaning the knife between slices for clean cuts. Serve chilled, garnished with additional lime zest if desired. These delightful lime pie bars are now ready to wow your guests and provide a refreshing treat for any gathering!

Expert Tips for Lime Pie Bars Taste as You Go: Before adding egg yolks to the filling, taste the mixture to adjust sweetness. This ensures a balanced flavor in your Lime Pie Bars. Watch the Bake Time: Avoid overbaking; the bars should have a gentle jiggle in the center. They will firm up perfectly while chilling in the fridge. Perfect Cuts: For cleaner slices, wipe the knife with a damp cloth between cuts. This keeps the layers of your lime pie bars distinct and beautiful.

Make Ahead Options These Lime Pie Bars are perfect for busy home cooks looking to save time without sacrificing flavor! You can prepare the crust and filling up to 24 hours in advance; simply store them separately in the refrigerator (cover tightly to maintain freshness). For optimal results, only bake the bars when you’re ready to chill and serve them. Once baked and cooled, refrigerate for at least 4 hours, or overnight, to allow the flavors to meld beautifully. Remember to whip the cream just before serving to ensure it remains light and fluffy, giving your Lime Pie Bars a delightful finish. Enjoy the convenience of making these delicious treats ahead of time for your next gathering! Lime Pie Bars Recipe FAQs What type of limes should I use for the best flavor? For the most authentic taste, I recommend using fresh key limes. They provide that signature tartness. If key limes aren’t available, you can use regular limes, but you may want to use slightly less juice to keep the balance of flavors. How should I store Lime Pie Bars? To keep your Lime Pie Bars fresh, store them in an airtight container in the refrigerator for up to 3-4 days. This will help maintain their creamy texture and delicious flavor. For longer storage, you can freeze them—just wrap tightly in plastic wrap and place them in a freezer-safe container. Can I freeze Lime Pie Bars? Absolutely! To freeze, first, cut the bars into individual pieces and wrap each piece tightly in plastic wrap. Then, place them in a freezer-safe container. They can be frozen for up to 2 months. When you’re ready to eat them, thaw the bars in the fridge overnight for the best texture. What should I do if my bars are too soft once baked? If your Lime Pie Bars are too soft after baking, it might be because they were not baked long enough. Remember, they should be slightly jiggly in the center when you take them out. If this happens, let them chill in the refrigerator longer. This resting time allows them to set properly. Are there any allergy concerns I should be aware of? When preparing Lime Pie Bars, keep in mind that sweetened condensed milk and egg yolks contain dairy and eggs, which are common allergens. You can use coconut-based sweetened condensed milk and a vegan egg substitute like silken tofu or extra yogurt for a dairy-free and vegan option, which can accommodate those with dietary restrictions. How far in advance can I make these bars? You can make Lime Pie Bars up to 3 days in advance. Just prepare everything, chill them, and then add the whipped cream on top right before serving to keep it light and fluffy. This makes them perfect for entertaining or unexpected guests!
