Ingredients
- 1 1/2 cups all-purpose flour

- 1/3 cup fresh lemon juice

Instructions
- Step 1: Preheat oven to 350°F. In a large bowl, combine 1 1/2 cups all-purpose flour, 1/4 cup granulated sugar, and 1/2 tsp baking powder. Cut in 3/4 cup cold cubed unsalted butter with a pastry cutter until mixture is crumbly. Press half the mixture into a greased 8x8-inch baking pan to form a crust.
- Step 2: In another bowl, whisk together 3 large eggs, 1/3 cup fresh lemon juice, 1 tbsp lemon zest, and 1/2 cup granulated sugar until smooth. Gently fold in 1 cup fresh blueberries.
- Step 3: Pour the lemon-blueberry mixture evenly over the crust in the pan.
- Step 4: Sprinkle the remaining crumb mixture evenly over the top as a streusel.
- Step 5: Bake for 35-40 minutes until the top is golden and the filling is set but slightly jiggly in the center.
- Step 6: Let cool completely in the pan for 1 hour, then dust with powdered sugar. Cut into 12 bars and serve.
