Equipment

  • 8×8-inch Baking Pan
  • Mixing Bowl
  • Whisk
  • Parchment Paper
  • Spatula

Ingredients
  

For the Lemon Blueberry Bars

  • 0.75 cup granulated sugar
  • 2 tbsp lemon zest
  • 1 cup salted butter regular or plant-based, softened
  • 1 tsp vanilla extract
  • 2.33 cups gluten-free 1:1 flour blend
  • 0.5 tsp fine sea salt

For the Blueberry Filling

  • 3 cups blueberries fresh or frozen
  • 2 tbsp lemon juice freshly squeezed
  • 0.25 cup granulated sugar
  • 1 tbsp cornstarch

For the Lemon Glaze

  • 0.25 cup powdered sugar
  • 0.5 tbsp lemon juice for glaze

Instructions
 

  • Preheat the oven to 350°F (175°C). Line an 8×8-inch pan with parchment paper in both directions and lightly spray with non-stick spray.
  • In a large bowl, rub sugar and lemon zest together. Add butter and vanilla. Mix until pale and fluffy.
  • Add gluten-free flour and sea salt. Mix on low speed until a crumbly dough forms.
  • Press two-thirds of the dough into the prepared pan to form the crust. Set aside remaining dough.
  • In a separate bowl, toss blueberries with sugar, lemon juice, and cornstarch. Gently spread over the crust layer.
  • Crumble the reserved dough evenly over the berry layer. Bake for about 60 minutes or until the top is golden and the filling is bubbling at the edges.
  • Cool completely in the pan. Whisk powdered sugar and lemon juice for the glaze, and drizzle over cooled bars before slicing.

Notes

For best results, let the bars cool and chill briefly before slicing. They store well and can be made ahead — perfect for summer brunches, picnics, or a nostalgic afternoon tea treat.
