For the Shortbread Crust:
- ¾ cup (150g) granulated sugar
- 2 tablespoons lemon zest
- 1 cup (227g) salted butter, room temperature (regular or plant-based)
- 1 teaspoon vanilla extract
- 2 ⅓ cups (280g) gluten-free flour 1:1 baking blend
- ½ teaspoon fine sea salt
For the Blueberry Filling:
- 3 cups (444g) fresh blueberries
- 2 tablespoons (30ml) lemon juice
- ¼ cup (50g) granulated sugar
- 1 tablespoon (8g) cornstarch
For the Lemon Glaze:
- ¼ cup (30g) powdered sugar
- ½ tablespoon lemon juice
- Preheat and Prepare Pan: Preheat your oven to 350ºF (175ºC). Spray an 8×8-inch baking pan with non-stick baking spray and line it with two pieces of parchment paper placed crisscrossed for easy removal.
- Mix Sugar and Lemon Zest: In a stand mixer bowl or a large mixing bowl using an electric mixer, beat the granulated sugar and lemon zest on high speed for 1 minute to release the citrus oils and infuse the sugar.
- Add Butter and Vanilla: Incorporate the room temperature butter and vanilla extract into the sugar mixture. Beat on high speed for 2 to 3 minutes until the mixture turns light and fluffy, indicating air incorporation.
- Add Flour and Salt: Lower the mixer speed to low and add the gluten-free flour blend along with the fine sea salt. Mix until a crumbly dough forms, ensuring everything is well combined but do not overmix.
- Form the Base: Take two-thirds of the dough and press it evenly into the prepared baking pan, forming the shortbread crust. Set aside the remaining dough for the topping.
- Prepare Blueberry Filling: In a small bowl, combine the fresh blueberries, granulated sugar, lemon juice, and cornstarch. Gently toss until the blueberries are coated evenly with the mixture.
- Assemble Bars: Spoon the blueberry filling evenly over the shortbread crust, taking care to leave any excess liquid behind so the base doesn’t get soggy.
- Add Crumble Topping: Crumble the reserved dough over the blueberry filling evenly to create the topping layer.
- Bake: Place the pan in the preheated oven and bake for approximately 60 minutes or until the topping is lightly golden and the filling is bubbling around the edges.
- Cool Completely: Remove the bars from the oven and allow them to cool completely in the pan to fully set the filling and crust, about 1 to 2 hours.
- Prepare Lemon Glaze: In a small bowl, whisk together the powdered sugar and lemon juice until smooth and drizzle-able.
- Glaze and Serve: Drizzle the lemon glaze over the cooled bars, slice into squares, and serve. Enjoy the zesty, fruity treat!
- Storage: Store any leftovers in an airtight container refrigerated for up to 5 days or freeze for up to 3 months. Thaw before serving for best texture.
Notes
- Ensure the butter is at room temperature for easy mixing and fluffy texture.
- Use fresh blueberries for best flavor and texture; frozen berries may release too much moisture.
- Press the dough evenly and firmly to form a sturdy base that holds up to the juicy filling.
- Monitor baking time closely; ovens vary and overbaking can dry out the bars.
- For a vegan version, use plant-based butter and ensure your gluten-free flour blend contains no animal products.
- The glaze is optional but adds a nice tangy sweetness to complement the berries.
- Use parchment paper to lift bars easily from the pan after baking.
