Instructions
- Preheat the oven to 350°F (175°C). Spray an 8×8-inch baking pan with non-stick spray and line it with parchment paper strips.
- In a mixing bowl, combine ¾ cup (150g) granulated sugar and 2 tablespoons lemon zest. Beat on high speed for 1 minute.
- Add 1 cup (227g) salted butter and 1 teaspoon vanilla. Beat on high for 2–3 minutes until light and fluffy.

- Reserve about ⅓ of the dough for the topping and press the remaining ⅔ into the prepared pan.
- In another bowl, combine 3 cups blueberries, 2 tablespoons lemon juice, ¼ cup granulated sugar, and 1 tablespoon cornstarch. Gently toss the blueberries.
- Spoon the blueberry mixture on top of the shortbread base, leaving excess liquid in the bowl.
- Crumble the reserved dough over the blueberry layer.
- Bake for approximately 60 minutes until lightly golden and juices are bubbling at the edges.
- Cool completely in the pan before slicing into squares.
- Whisk ¼ cup powdered sugar with ½ tablespoon lemon juice until smooth and drizzle over cooled bars.
- Slice into 16 squares and enjoy.
Notes
For lower sugar options, reduce the sugar in the filling and use a powdered sugar substitute. Use frozen blueberries without thawing to maintain moisture balance.
