Ingredients
  

For the crust

  • 1.5 cups 1 1/2 cups gluten-free all-purpose flour blend (with xanthan gum)
  • 0.5 cups 1/2 cup powdered sugar, plus extra for dusting Extra powdered sugar for dusting before serving
  • 0.25 teaspoon 1/4 teaspoon fine salt
  • 10 tablespoons 10 tablespoons unsalted butter, cold and cubed

For the filling

  • 3 large 3 large eggs, room temperature Room temperature for better incorporation
  • 1 cup 1 cup granulated sugar
  • 2 tablespoons 2 tablespoons gluten-free all-purpose flour blend
  • 0.5 teaspoon 1/2 teaspoon baking powder
  • 2 zest Zest of 2 lemons Use fresh for better flavor
  • 0.5 cups 1/2 cup fresh lemon juice (about 2–3 lemons) Fresh juice preferred over bottled

Instructions
 

Preheat and Prep

  • Preheat the oven to 350°F (175°C) and line an 8x8-inch pan with parchment paper, leaving an overhang.

Make the Crust

  • In a medium bowl, whisk together 1 1/2 cups gluten-free flour, 1/2 cup powdered sugar, and 1/4 teaspoon salt.
  • Cut in the cold cubed butter until the mixture resembles coarse crumbs.
  • Press the mixture firmly into the prepared pan in an even layer.
  • Bake for 15–18 minutes or until the edges are lightly golden. Remove and let cool slightly.

Whisk the Filling

  • In a bowl, whisk together the eggs, granulated sugar, 2 tablespoons gluten-free flour, baking powder, lemon zest, and lemon juice until smooth.

Bake Again

  • Pour the lemon filling over the warm crust.
  • Return to the oven and bake for 18–22 minutes, until the filling is set but still slightly jiggly in the center.
  • Cool completely in the pan, then chill for at least 2 hours to firm up for clean slices.

Serve

  • Use the parchment overhang to lift the slab out, dust with powdered sugar, and slice into squares.

Notes

Use fresh lemon juice and zest for the best flavor; room-temperature eggs provide a silky texture. Chill the bars before slicing to achieve cleaner cuts. If your gluten-free flour blend doesn’t contain xanthan gum, add 1/4 teaspoon of xanthan gum for better structure.
