Key Lime Shortbread Bars Recipe
Description
This Key Lime Shortbread Bars recipe begins with a classic shortbread crust made from butter, flour, and confectioner’s sugar pressed into a pan and baked until lightly golden. After cooling, a filling is prepared by whisking egg yolks with sweetened condensed milk, key lime juice, lime zest, lemon juice, and granulated sugar.
The egg whites are beaten separately with sugar until soft peaks form, then folded gently into the filling to add lightness. This mixture is spread over the cooled crust and baked at a lower temperature until set but still tender. The bars are then chilled thoroughly, which firms the citrus layer for clean slicing.
These bars offer a balance of rich, buttery shortbread and bright, tart key lime filling, making them a refreshing dessert option. They are typically served cold and garnished with whipped cream and lime slices or zest for visual appeal and enhanced flavor.
