Ingredients
- 1 cup gluten-free all-purpose flour

- 1/4 teaspoon salt
- 1/2 cup unsalted butter, melted
- 1 cup granulated sugar
- 3 large eggs
- 1/3 cup fresh lemon juice
- 1 tablespoon lemon zest
- 1/4 cup gluten-free all-purpose flour
- Powdered sugar for dusting

Directions
Prepare the Shortbread Crust
Preheat your oven to 350°F (175°C). In a medium bowl, mix together the gluten-free flour, powdered sugar, and salt. Stir in the melted butter until well combined. Press the mixture evenly into an 8×8 inch baking pan lined with parchment paper. Bake for 20 minutes or until lightly golden.

Make the Lemon Filling
While the crust is baking, whisk together the granulated sugar, eggs, lemon juice, lemon zest, and flour in a large bowl until smooth. Pour the mixture over the hot crust once it’s done baking.
Bake the Lemon Bars
Return the pan to the oven and bake for an additional 20-25 minutes, or until the filling is set. Allow the bars to cool completely, then dust with powdered sugar before cutting into squares.
