- Active Time: 20 minutes
Crust:
- 1 stick (8 tablespoons) unsalted butter, softened to room temperature
- 1/4 cup granulated sugar
- 1 tablespoon freshly grated lime zest
- 1 cup all-purpose flour
- 1/4 teaspoon kosher salt
Filling:
- 1 large egg plus 3 egg yolks
- 1 tablespoon lime zest plus 1/2 cup freshly squeezed lime juice
- One 14-ounce can sweetened condensed milk
Topping:
- 2 to 3 tablespoons granulated sugar, for sprinkling
- 4 thin lime slices, each cut into quarters
Instructions:
- Preheat your oven to 350F and line an 8-inch square baking pan with foil, leaving a 1-inch overhang on all sides for easy removal.
- Make the crust: In a stand mixer with paddle attachment, beat softened butter, sugar, and lime zest on high until light and fluffy, about 2 minutes. Scrape down sides, add flour and salt, then mix on low until it forms loose crumbs. Press evenly into the prepared pan and bake 15-18 minutes until lightly golden. Cool completely on a wire rack.
- Prepare the filling: Whisk egg, yolks, lime zest, lime juice, and condensed milk in a bowl until smooth and silky. Pour over cooled crust and bake 18-20 minutes until set. Cool on rack, then chill in fridge at least 3 hours until firm.
- Add the topping: Preheat broiler. Lift bars from pan using foil overhang, trim edges if needed, and cut into 16 squares on a foil-lined baking sheet. Sprinkle sugar evenly over tops and broil 1-2 minutes until caramelized and bubbly. Cool slightly, garnish with lime quarters, and enjoy these zesty, creamy treats!
