Ingredients
For the Shortbread Crust
For the Filling
Instructions
- Step 1
Preheat oven to 350 degrees. Line an 8×8" baking dish with parchment paper or foil.
- Step 2
Prepare the crust. In a large bowl, beat the butter and 1/4 cup powdered sugar till light and fluffy, about 2-3 minutes. Add flour and salt, and beat on low speed until just incorporated.
- Step 3
Scrape the dough into the prepared pan and spread evenly with an offset spatula. Bake on the middle rack of the oven 20-25 minutes, or until lightly golden. Remove from the oven and cool on a wire rack while you prepare the filling.
- Step 4
Prepare the filling. In a medium bowl, whisk the eggs and granulated sugar until well incorporated. Add the 3 tablespoons of flour and whisk until combined, then whisk in the lime juice and zest.
- Step 5
Pour the filling over the cooled crust, and bake 20-25 minutes longer, or until the filling has set. The filling will not "wiggle" when the pan is moved gently back and forth. Remove from heat and cool completely on a wire rack.
- Step 6
Once the key lime bars have cooled, cut into squares with a sharp knife, wiping the knife clean in between slices. Dust with powdered sugar, serve and enjoy!
