These lemon bars make a lovely dessert for any occasion and are easy to make and turn out so beautifully. They need at least 3 hours to cool and then chill before serving.



Shortbread Crust

  • 2 cups gluten-free flour mix*
  • 1 cup dairy-free buttery spread, melted
  • 1/2 cup sugar
  • 2 teaspoons vanilla
  • 1/2 teaspoon salt

Lemon Filling

  • 2 cups sugar
  • 6 large eggs
  • 3/4 cup fresh lemon juice (4 lemons)
  • 1/3 cup of gluten-free flour*

powdered sugar for dusting 


  • Preheat oven to 325°. Prepare a 9×13 baking pan by lining it with parchment paper or grease with cooking spray.
  • In a medium bowl mix together the non-dairy butter, vanilla, flour, sugar, and salt.
  • Press the batter into the prepared pan and bake for 20-24 minutes until the edges are browned.
  • While the shortbread bakes prepare the lemon custard by whisking together the eggs, lemon juice,sugar, and flour.
  • When the shortbread is finished baking poke some holes along the top side of the crust with a fork. Next, pour the lemon mixture over the warm shortbread crust and then bake for around 25 minutes until the center is not jiggly. 
  • Remove from the oven and set on a wire rack to cool. Let the lemon bars cool for one hour and then chill in the refrigerator for at least two hours before serving.
  • Dust the top with powdered sugar before serving.
  • Store lemon bars covered in the refrigerator for up to one week.


*My favorite gluten-free & dairy-free flour blends to use are Pamela’s Artisan Blend and Better Batter.

**My favorite non-dairy butter is Plant-Based Country Crock or Smart Balance. If you don’t need to make these dairy-free you can substitute with real butter.
