Step-by-Step Instructions
1
Preheat your oven to 375°F (190°C). Line an 8-inch square baking dish with parchment paper or aluminum foil, leaving some overhang for easy removal.
2
In a medium bowl, whisk together the flour, granulated sugar, and salt. Add the cold butter and use a pastry blender or your fingers to work it into the dry ingredients until the mixture resembles coarse crumbs.
3
Press the mixture evenly into the prepared baking dish. Bake for 20-25 minutes, or until the crust is lightly golden brown.
4
In a large bowl, whisk together the confectioners' sugar, cornstarch, and cinnamon. Add the blackberries and toss to coat. Let it sit for about 15 minutes, until the berries start to release their juice and the mixture becomes syrupy.
5
In another bowl, mix together the rolled oats, brown sugar, and a pinch of salt. Add the cold butter and use your fingers or a pastry blender to work it into the dry ingredients until the mixture resembles coarse crumbs.
6
Spread the blackberry mixture over the baked crust. Top with the oat mixture, spreading it evenly to cover the entire surface.
7
Bake for an additional 35-40 minutes, or until the topping is golden brown and the filling is bubbly. Let it cool completely in the pan before cutting into bars and serving.
