Ingredients

Scale

For the Crust

  • 1½ cups gluten free flour (222g)
  • ½ cup granulated sugar (100g)
  • ½ cup salted butter (113g, cold and cut into pieces, dairy-free butter works well)
  • 2 tbsp water (28 ml)

For the Filling

  • 1½ cups granulated sugar (300g)
  • ½ cup lemon juice (118ml, from 4 lemons, Meyer lemons preferred for sweeter flavor)
  • 2 tbsp grated lemon zest (12g, from 2 lemons)
  • 4 large eggs (lightly beaten)
  • ¼ cup gluten free flour (37g)

For Garnish

  • Powdered sugar (optional, for sprinkling)

Instructions

  1. Preheat Oven: Preheat your oven to 350°F (175°C). Prepare a 9×9-inch baking pan by spraying it with nonstick spray. Optionally, line the pan with foil before spraying to make removing the bars easier after baking.
  2. Make the Crust: In a medium bowl, combine the gluten-free flour and granulated sugar. Use a fork or knives to cut the cold butter into the dry ingredients until the mixture becomes crumbly. Slowly add the water a tablespoon at a time while mixing to form a dough.
  3. Press and Bake Crust: Press the crust mixture evenly into the bottom of the prepared pan. Bake in the preheated oven for about 25 minutes, or until the crust is slightly golden and set.
  4. Prepare the Filling: In a large bowl, whisk together the granulated sugar, lemon juice, lemon zest, eggs, and gluten-free flour until the mixture is completely smooth and well combined.
  5. Pour Filling Over Crust: While the crust is still hot, pour the lemon filling mixture evenly over the crust in the pan.
  6. Bake Lemon Bars: Return the pan to the oven and bake for 22-26 minutes, or until the filling is set in the middle but still slightly jiggly.
  7. Cool Completely: Remove the pan from the oven and allow the lemon bars to cool completely on the counter for at least 2 hours. This helps the filling firm up for clean slicing.
  8. Slice and Serve: Once cooled, cut the bars into squares. Optionally, sprinkle with powdered sugar before serving for an elegant touch.

Notes

  • Use Meyer lemons if possible for a sweeter, less acidic filling.
  • For easier removal, lining the pan with foil before spraying is recommended.
  • Dairy-free butter can be used to make this recipe suitable for those avoiding dairy.
  • Ensure the lemon bars are fully cooled before slicing to avoid crumbling.
  • Powdered sugar is optional but adds a nice visual and subtle sweetness on top.
