  • 1 ¾ cups all-purpose flour
  • 1 cup salted butter
  • cup powdered sugar
  • ¼ cup cornstarch
  • ¼ teaspoon salt


  • 2 ½ cups granulated sugar
  • ½ cup all-purpose flour
  • 2 Tablespoons lemon zest
  • 1 cup fresh lemon juice
  • 8 large egg yolks
  • Powdered sugar for dusting


  • Preheat oven to 350 degrees F. Line a 9x13" pan with a parchment paper sling.
  • In a food processor, add the flour, powdered sugar, cornstarch, salt, and butter. Pulse until the butter is cut in really well, then press the mixture into the prepared pan.
  • Bake the crust for 15-20 minutes until just barely starting to brown around the edges.
  • While crust bakes, prepare the lemon filling by whisking together the sugar, flour, and lemon zest in a large bowl. Add the lemon juice and eggs, whisking well until combined.
  • Pour the filling over the crust, then decrease oven heat by 25 degrees to 325 degrees F and bake for another 22-26 minutes until the lemon bars are set and no longer jiggling in the center. Remove from oven and cool completely.
  • Dust with powdered sugar, then cut into squares. Store in fridge until ready to serve.


  • Smaller Batch: You can halve the recipe and bake in an 8- or 9-inch square pan if you only want 9-12 lemon bars. You can decrease the baking time for the filling to about 20 minutes if you decide to take this approach.
