Can I use bottled lime juice instead of fresh?

While technically possible, I really don't recommend it. Fresh lime juice has a vibrant brightness that bottled juice simply can't match. Plus, you'll need fresh limes for the zest anyway, which is crucial for that intense lime flavor. The few extra minutes it takes to squeeze fresh limes will be well worth it in the final taste.

Why did my filling crack on top?

A few small cracks are normal and will be hidden by the confectioners' sugar. However, significant cracking usually happens when the bars cool too quickly. Try turning off the oven, opening the door slightly, and letting the bars cool more gradually for the first 10 minutes before removing them completely.

Can I make these bars gluten-free?

Absolutely! Simply substitute the all-purpose flour with a 1:1 gluten-free baking flour blend in both the crust and filling. Many bakers report excellent results with this simple swap. Just make sure your blend contains xanthan gum for proper binding.

How do I know when the filling is properly set?

The filling should look set around the edges with a slight jiggle in the center when you gently shake the pan. It will continue to set as it cools, so don't worry if it seems a bit soft in the middle. If you bake until completely firm, the texture may become too rubbery rather than silky.

Instructions

Prepare the Pan: Preheat oven to 350°F (175°C). Lightly spray an 8×8-inch baking dish with nonstick cooking spray to prevent sticking and ensure easy removal of bars.
Make the Crust: In a medium bowl, mix together the softened butter, all-purpose flour, and granulated sugar until the mixture is crumbly but holds together when pressed. This forms the buttery base of your bars.
Press the Crust: Firmly and evenly press the crust mixture into the bottom of the prepared pan, using your fingers or the bottom of a measuring cup to create an even layer.
Bake the Crust: Bake the crust for 15 to 20 minutes, or until the edges are a light golden brown. Remove from oven but keep oven on for the next step.
Prepare the Filling: While the crust bakes, in a medium bowl, whisk together the lightly beaten eggs, granulated sugar, flour, baking powder, fresh lime juice, and lime zest until the mixture is smooth and well combined.
Add the Filling: As soon as the crust comes out of the oven, pour the lime filling over the hot crust, spreading it evenly.
Bake the Bars: Return the pan to the oven and bake for an additional 15-20 minutes, or until the filling is just set in the center, and the edges are lightly golden.
Finish and Cool: Remove from oven and immediately dust the top with confectioners’ sugar. Allow the bars to cool completely to room temperature, then refrigerate overnight for best texture and flavor.
Serve: Cut the chilled bars into squares and serve. Enjoy your refreshing lime dessert!

Notes

For best lime flavor, use freshly squeezed lime juice and fresh lime zest.
Refrigerating overnight helps the bars set and enhances flavor.
Bars can be stored in an airtight container in the refrigerator for up to 5 days.
If desired, add extra lime zest on top for added color and zing before serving.
