Equipment

  • 9x13-inch baking pan
  • Mixing bowls
  • Whisk
  • Zester or grater
  • Measuring cups and spoons
  • Oven

Ingredients
  

For the Crust:

  • 1 cup 2 sticks unsalted butter, softened
  • 2 cups all-purpose flour
  • 1/2 cup granulated sugar
  • Pinch of salt

For the Lemon Filling:

  • 3-4 large lemons juice and zest
  • 4 large eggs
  • 1 1/2 cups granulated sugar
  • 1/4 cup all-purpose flour

For the Crumb Topping:

  • 3/4 cup 1 1/2 sticks unsalted butter, softened
  • 1 cup all-purpose flour
  • 1 cup brown sugar packed
  • Pinch of salt

Instructions
 

  • Preheat oven to 350°F (175°C). Line a 9x13 inch pan with parchment paper, leaving overhang for easy removal.
  • Make the crust: In a mixing bowl, combine butter, flour, sugar, and salt. Mix until crumbly but holds together when pressed. Press firmly into the bottom of the prepared pan. Bake for 10 minutes until just set and lightly golden.
  • Prepare the lemon filling: Whisk together eggs, sugar, lemon juice, lemon zest, and flour until smooth and fully combined.
  • Pour the lemon filling over the warm crust.
  • Make the crumb topping: Combine butter, flour, brown sugar, and salt until crumbly (do not overmix). Sprinkle evenly over the lemon filling.
  • Bake for an additional 30 minutes, or until the topping is golden and the filling has a slight jiggle in the center.
  • Cool completely in the pan on a wire rack. Once cool, refrigerate for at least 2 hours or overnight for best results.
  • Use parchment overhang to lift bars from the pan. Cut into 16 squares and serve. Dust with powdered sugar if desired.

Notes

Use fresh lemon juice and zest for best flavor.
Do not overbake the filling; it should have a slight jiggle.
Let bars cool completely before cutting to avoid a messy filling.
Bars taste better the next day after flavors meld.
Can be stored at room temperature (2-3 days), refrigerated (up to 1 week), or frozen (up to 3 months).
