Ingredients
  

Crust Ingredients

  • 1 cup unsalted butter, melted adds richness and moisture
  • 1/2 cup granulated sugar provides sweetness and structure
  • 1 teaspoon pure vanilla extract enhances overall flavor
  • 1/2 teaspoon salt balances sweetness
  • 2 cups gluten-free all-purpose flour with xanthan gum gives structure and texture

Filling Ingredients

  • 6 large eggs provides stability and moisture
  • 2 cups granulated sugar adds sweetness for the filling
  • 1 cup lemon juice (about 4 lemons) gives a fresh, tangy flavor
  • 1/2 teaspoon pure vanilla extract adds depth to the filling
  • 1/2 cup gluten-free all-purpose flour with xanthan gum thickens filling
  • powdered sugar for dusting adds sweetness and visual appeal

Instructions
 

Preparation

  • Preheat your oven and prepare the baking pan (greased or lined with parchment paper).
  • In a mixing bowl, combine the melted butter with 1/2 cup of granulated sugar, whisking until smooth.
  • Stir in the vanilla extract and salt until well combined.
  • Gradually add 2 cups of gluten-free all-purpose flour, gently combining until a cohesive dough forms.
  • Press the crust mixture evenly into the bottom of your prepared baking pan.
  • Bake the crust in the preheated oven for about 20–25 minutes until lightly golden.

Filling Preparation

  • While the crust is baking, whisk together the eggs in a clean mixing bowl until frothy.
  • Add 2 cups of granulated sugar to the eggs, whisking until smooth.
  • Stir in the lemon juice and the additional vanilla extract until well mixed.
  • Gradually mix in the 1/2 cup of gluten-free all-purpose flour until fully combined.

Final Baking

  • Once the crust is done and slightly cooled, pour the lemon filling over it.
  • Return the pan to the oven and bake for another 20–25 minutes until the filling is set but slightly jiggles in the center.
  • Cool the lemon bars to room temperature in the pan before slicing.
  • Dust with powdered sugar before serving.

Notes

For best results, let the crust cool slightly before adding the filling. Always use freshly squeezed lemon juice for optimal flavor.
