Bright Zesty Lemon Bars (Printable Version)

Bright, zesty bars with buttery crust and tangy lemon filling, ideal for dessert or afternoon tea.

# What You Need:

→ Shortbread Crust

01 - 1 cup unsalted butter, softened
02 - 1/2 cup granulated sugar
03 - 2 cups all-purpose flour
04 - 1/4 teaspoon salt

→ Lemon Filling

05 - 1 1/2 cups granulated sugar
06 - 1/4 cup all-purpose flour
07 - 4 large eggs
08 - 2/3 cup freshly squeezed lemon juice
09 - 1 tablespoon finely grated lemon zest

→ Dusting

10 - Powdered sugar for dusting

# How To Make:

01 - Preheat oven to 350°F. Line a 9x13 inch baking pan with parchment paper, leaving an overhang for easy removal.
02 - In a medium bowl, cream together the butter and sugar until light and fluffy. Incorporate flour and salt, mixing just until combined. Press mixture evenly into bottom of prepared pan.
03 - Bake crust for 18 to 20 minutes, until edges turn lightly golden.
04 - While crust bakes, whisk sugar and flour in a large bowl. Add eggs, lemon juice, and lemon zest; whisk until smooth and fully combined.
05 - Pour filling over hot crust. Return pan to oven and bake 15 to 18 minutes, until filling is set and slightly jiggles in the center.
06 - Remove pan from oven and cool completely on wire rack. Refrigerate at least 2 hours for clean slicing.
07 - Lift bars from pan using parchment overhang. Dust generously with powdered sugar and cut into 16 squares.

# Expert Advice:

01 -
  • The crust stays buttery and tender even after days in the fridge—no stale, crumbly disappointments here.
  • Fresh lemon juice and zest mean you actually taste the citrus, not just a vague lemony idea of lemon.
  • These come together faster than you'd think, perfect for when you want homemade dessert without spending your whole afternoon in the kitchen.
02 -
  • Don't skip the chilling step—I learned this the hard way when I tried to cut warm bars and ended up with a delicious but structurally unfortunate mess on a plate.
  • Fresh lemon juice makes an absolute difference; if you use bottled, the bars taste vaguely citrusy instead of actually tasting like lemon, and that's the whole point.
  • Slightly underbaking the filling is better than overbaking it—that gentle jiggle in the center means it's going to be creamy and perfect, not dense and rubbery.
03 -
  • Use a microplane to zest your lemons—it captures all that fragrant yellow oil without the bitter white pith underneath, and it makes a real difference in the final flavor.
  • Room temperature eggs blend smoothly into the filling without creating those little flecks of cooked egg white that show up when cold eggs hit the hot crust.
  • If your lemon bars are browning around the edges too quickly, tent the pan loosely with aluminum foil for the last few minutes of baking.
