Why You’ll Love This Recipe
These Key Lime Pie bars are not just a taste of sunshine; they are an embodiment of convenience and sophistication. Easy to prepare with a handful of ingredients, they offer all the lusciousness of a classic key lime pie without the fuss of a pie crust. They are perfect for casual gatherings, picnics, or simply indulging in a quiet moment. Their ability to capture a creamy texture with just the right amount of zestiness makes them a standout dessert.
Ingredients Notes
To achieve the signature tartness, fresh key limes are the star of the show. If they’re not available, Persian limes can be a good substitute. Use Sweetened Condensed Milk for the creamy filling, and remember, the quality of your graham crackers influences the crust’s texture. For a gluten-free option, almond flour combined with sugar makes an excellent crust substitute.
Recipe Steps
Step 1
Preheat your oven to 350°F (175°C). Line an 8×8 inch baking dish with parchment paper, leaving an overhang on all sides for easy removal later.
Step 2
Prepare the crust by crushing graham crackers until fine. Mix with melted butter and sugar, pressing the mixture evenly into the bottom of the prepared dish. Bake for 10 minutes and set aside to cool.
Step 3
In a bowl, whisk the egg yolks and lime zest until pale. Slowly mix in the sweetened condensed milk, followed by the lime juice. Keep mixing until smooth and creamy.
Step 4
Pour the filling over the cooled crust, spreading it evenly. Return the pan to the oven and bake for about 15 minutes, or until the filling has just set.
Step 5
Allow the bars to cool to room temperature, then refrigerate for at least 2 hours. Once chilled, use the parchment overhang to lift the bars out and slice into squares to serve.
Storage Options
Store any leftover bars in an airtight container in the refrigerator for up to a week. For longer storage, wrap each bar individually with plastic wrap and place in a freezer-safe bag. They can be frozen for up to two months; simply thaw in the fridge overnight or leave at room temperature for a couple of hours before serving.
Variations & Substitutions
For a twist on traditional flavors, try replacing lime juice with lemon or a mix of citrus juices. To make a vegan version, use Coconut Cream in place of sweetened condensed milk and egg substitutes for thickening.
Serving Suggestions
These bars are perfect for a summer brunch or as a refreshing conclusion to a hearty BBQ. Serve them chilled with a dollop of whipped cream and a sprig of mint for an elegant touch. They pair beautifully with iced tea or a crisp, cool Chardonnay.
Frequently Asked Questions
Can I use bottled lime juice instead of fresh? While you can use bottled lime juice, fresh lime juice offers a more vibrant flavor that’s worth the extra effort. The zest from fresh limes also adds an additional depth of lime essence.
What should I do if the filling doesn’t seem set? Ensure that you bake the filling until it’s just set—it should slightly jiggle but not be liquidy. Allow it to cool completely to help it firm up. If issues persist, check your oven temperature with a thermometer to ensure accuracy.
How can I make these bars healthier? Consider reducing the sugar in the crust and exploring low-sugar sweetened condensed milk options. Alternatively, substituting some of the condensed milk with Greek yogurt can offer a lower calorie and protein-rich alternative without sacrificing creaminess.
