How to Make Lime Bars
- Preheat the oven to 350°F and line an 11×7-inch baking pan with parchment paper, allowing extra paper to hang over the sides for easy removal later.
- In a medium mixing bowl, combine the flour, powdered sugar, and salt until evenly mixed.
- Add the cold cubed butter into the dry ingredients and pulse with a food processor or cut in using a pastry cutter until the mixture resembles fine crumbs.
- Press the crumb mixture firmly and evenly into the prepared baking pan to create a compact shortbread crust layer.
- Bake the crust for 18 to 20 minutes until lightly golden and firm around the edges while preparing the filling.
- In a large bowl, whisk together the granulated sugar and flour until no lumps remain in the mixture.
- Add the eggs one at a time, whisking thoroughly after each addition to create a smooth and silky custard base.
- Stir in the fresh lime zest and freshly squeezed lime juice until fully incorporated and fragrant.
- Add a small drop of green food coloring if desired to achieve a brighter lime appearance without overpowering the natural look.
- Remove the hot crust from the oven and immediately pour the lime filling evenly over the warm crust for better baking results and a smooth custard layer.
- Return the pan to the oven and bake for another 18 to 20 minutes until the filling is set and no longer jiggles in the center.
- Remove the bars from the oven and allow them to cool completely at room temperature before transferring them to the refrigerator.
- Chill the bars for at least 2 hours to help the filling firm up properly for clean slicing and the best texture.
- Lift the bars from the pan using the parchment overhang and place them on a cutting board for slicing.
- Dust generously with powdered sugar just before serving for a classic bakery-style finish.
