Lime Pie Bars Ingredients For the Crust • Graham Crackers – An essential for a crunchy texture; consider gluten-free alternatives if necessary. • Butter – This rich component binds the crust together; opt for vegan butter for a dairy-free version. For the Filling • Key Lime Juice – Bringing that signature tang; fresh key limes are preferred for optimal taste. • Zest of Key Limes – Adds aromatic citrus notes that enhance the flavor profile. • Sweetened Condensed Milk – Provides creaminess and sweetness; a non-dairy version is available for those avoiding dairy. • Vanilla Extract – Offers depth to the filling; pure vanilla is recommended for the best flavor. • Sour Cream or Yogurt – Balances acidity while adding creaminess; can substitute with cream cheese for a richer texture. • Egg Yolks – Crucial for setting the filling; for a vegan option, use additional yogurt, though this may affect firmness. For the Topping • Heavy Cream – Whipped to perfection for a light, airy finish; coconut cream serves as a wonderful dairy-free alternative. Now that you have the ingredients at your fingertips, get ready to create those scrumptious Lime Pie Bars that are sure to impress! 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-inch baking pan with parchment paper for easy removal. This will ensure your Key Lime Pie Bars come out of the pan nicely once they are set. Make sure to leave some overhang for easy lifting later. Step 2: Create the Crust In a food processor, pulse about 1 ½ cups of graham crackers until finely crushed. Add ½ cup of melted butter and mix until the texture resembles wet sand. Press this mixture firmly into the bottom of the prepared pan to form an even crust. Bake for 10 minutes or until golden and fragrant, then let it cool slightly. Step 3: Mix the Filling Zest and juice about 4-6 key limes, ensuring to avoid any seeds. In a mixing bowl, combine the key lime juice, zest, one can of sweetened condensed milk, 1 teaspoon of vanilla extract, and ½ cup of sour cream. Whisk until smooth and creamy, letting the fragrant citrus aroma fill your kitchen. Step 4: Add Egg Yolks Gently stir in 4 egg yolks into your creamy filling. Taste the mixture and adjust sweetness if needed before pouring it over the cooled crust. The vibrant key lime filling should be well-blended and luscious, with a zing that promises a delicious outcome. Step 5: Bake the Bars Carefully pour the filling over the crust in the pan and spread it evenly. Bake in the preheated oven for 15-20 minutes, or until the bars are set but still slightly jiggly in the center. This slight jiggle indicates that they will firm up beautifully as they cool. Step 6: Cool and Chill Once out of the oven, allow the Lime Pie Bars to cool at room temperature for about 30 minutes. After cooling, transfer the pan to the refrigerator and chill for at least 2 hours until they are fully set. This chilling step is crucial for achieving that perfect creamy texture. Step 7: Prepare the Topping In a separate bowl, whip 1 cup of heavy cream until stiff peaks form. This fluffy whipped cream will add a delightful lightness to your Lime Pie Bars. If you’re making it dairy-free, use chilled coconut cream instead. Step 8: Assemble and Slice Spread the whipped cream evenly over the chilled bars, creating a luscious topping. Carefully slice the bars into squares or rectangles with a sharp knife, wiping the blade in between cuts for clean edges. Serve your Lime Pie Bars chilled, garnished with additional lime zest if desired. How to Store and Freeze Lime Pie Bars Fridge: Keep the Lime Pie Bars wrapped tightly in plastic wrap or stored in an airtight container for up to 3-4 days. This will maintain their creamy texture and freshness. Freezer: For longer storage, freeze the bars in an airtight container for up to 2 months. Be sure to layer parchment paper between slices to prevent sticking. Thawing: When ready to enjoy, remove from the freezer and thaw in the refrigerator overnight. Re-whip the topping if needed for best results. Serving Tip: Always serve chilled for optimal flavor and texture, making your Lime Pie Bars a delightful refreshment on warm days!

Lime Pie Bars Recipe FAQs What kind of key limes should I use for the bars? I recommend using fresh key limes for the best flavor! They have a unique tartness that really makes these Lime Pie Bars shine. If key limes are not available, regular limes will work, just remember to reduce the amount a bit, as they are more acidic. How should I store leftover Lime Pie Bars? To keep your bars fresh, wrap them tightly in plastic wrap or store them in an airtight container in the fridge for up to 3-4 days. This will maintain their creamy texture and delicious taste, letting you enjoy them for a few days longer! Can I freeze Lime Pie Bars? Absolutely! To freeze, cut the bars into squares and layer them with parchment paper in an airtight container. They can be stored in the freezer for 2 months. When you’re ready to indulge, take them out and let them thaw in the refrigerator overnight. You might want to re-whip the topping to restore that fluffy texture! What if my Lime Pie Bars turn out too runny? If your bars don’t hold together well, it could be due to under-baking or not allowing enough time to chill. The center should be slightly jiggly when you take them out of the oven; they will firm up as they cool. Make sure to chill them for at least 2 hours, or up to overnight, for the best results. Can I make these bars dairy-free? Yes! For a dairy-free variation, simply swap the butter with vegan butter, use non-dairy sweetened condensed milk, and replace heavy cream with coconut cream for the topping. They’ll be just as delicious and creamy! Are these Lime Pie Bars suitable for pets? Lime is not safe for pets, especially dogs. The tartness of key limes can cause gastrointestinal issues. Always keep baking goods with lime away from your furry friends, and share with humans instead!
