Instructions

1. Preheat the oven to 350°F (175°C) and line a 9x9-inch baking dish with parchment paper, allowing some overhang for easy removal later.
2. In a mixing bowl, combine the gluten-free all-purpose flour blend, 1 cup of powdered sugar, and salt. Whisk until well mixed.
3. Add the cold, cubed butter to the dry ingredients. Use a pastry cutter or your fingers to cut the butter into the flour mixture until it resembles coarse crumbs.
4. Press the mixture evenly into the bottom of the prepared baking dish to form a crust.
5. Bake the crust in the preheated oven for 15 minutes, or until lightly golden and fragrant.
6. While the crust is baking, prepare the lemon filling. In a separate bowl, whisk together the eggs, granulated sugar, lemon juice, lemon zest, and baking powder until well combined and smooth.
7. Pour the lemon filling over the baked crust, spreading it evenly.
8. Return the dish to the oven and bake for an additional 20-25 minutes, or until the filling is set and the edges are lightly golden.
9. Remove from the oven and let the lemon bars cool completely in the baking dish on a wire rack.
10. Once cooled, dust the top with powdered sugar before cutting into squares. Serve and enjoy!
