Preheat your oven to 350°F (175°C) and line an 8x8-inch baking dish with parchment paper, leaving some overhang for easy removal.
In a large mixing bowl, combine the all-purpose flour, granulated sugar, and salt. Mix well.
Add the cold, cubed butter to the flour mixture. Using a pastry cutter or your fingers, blend the butter into the dry ingredients until the mixture resembles coarse crumbs.
Press 2/3 of the crust mixture firmly into the bottom of the prepared baking dish. Reserve the remaining 1/3 for the streusel topping.
In a medium bowl, mix the blueberries and chopped strawberries with the lemon juice and cornstarch until evenly coated.
Spread the berry mixture over the prepared crust in an even layer.
To make the streusel topping, stir the brown sugar, rolled oats, and vanilla extract into the reserved crust mixture.
Sprinkle the streusel topping evenly over the berry layer.
Bake in the preheated oven for 35-40 minutes, or until the topping is golden brown and the filling is bubbling.
Allow the bars to cool completely in the pan before lifting them out using the parchment paper overhang. Slice into 12 squares and serve.
