Ingredients

• 1.5 cups Gluten-free all-purpose flour
• 0.5 cup Powdered sugar
• 0.75 cup Unsalted butter, melted
• 0.25 teaspoon Salt
• 1.5 cups Granulated sugar
• 4 Eggs
• 1 tablespoon Lemon zest
• 0.75 cup Freshly squeezed lemon juice
• 0.25 cup Gluten-free all-purpose flour
• 0.5 teaspoon Baking powder
• 2 tablespoons Powdered sugar for dusting

Directions

Step 1

Preheat your oven to 350°F (175°C). Grease a 9x13-inch baking pan with cooking spray or line it with parchment paper.

Step 2

In a medium bowl, combine 1.5 cups of gluten-free all-purpose flour and 0.5 cup of powdered sugar. Add 0.75 cup of melted butter and 0.25 teaspoon of salt, then stir until the mixture is crumbly.

Step 3

Press the flour and butter mixture into the bottom of the prepared pan, spreading evenly to form the crust.

Step 4

Bake the crust in the preheated oven for 15-18 minutes, or until the edges are lightly golden.

Step 5

While the crust is baking, prepare the lemon filling. In a large mixing bowl, whisk together 1.5 cups of granulated sugar and four eggs until well combined.

Step 6

Add 1 tablespoon of lemon zest and 0.75 cup of freshly squeezed lemon juice to the egg mixture, whisking until smooth.

Step 7

In a separate small bowl, combine 0.25 cup of gluten-free all-purpose flour and 0.5 teaspoon of baking powder. Gradually whisk this mixture into the lemon filling until no lumps remain.

Step 8

Once the crust is done baking, pour the lemon filling over the hot crust.

Step 9

Return the pan to the oven and bake for 18-20 minutes, or until the lemon filling is set and the edges are firm.

Step 10

Remove from the oven and let the lemon bars cool completely in the pan on a wire rack.

Step 11

Once cool, dust the top generously with 2 tablespoons of powdered sugar.

Step 12

Cut into 16 squares and serve. Store leftover bars in an airtight container in the refrigerator.
