- Heat the oven to 350°F (175°C). Line an 8x8-inch pan with parchment, leaving overhang on two sides.
- In a large bowl, stir the flour, oats, brown sugar, baking soda, cinnamon and salt.
- Pour in the melted butter and stir until the mixture forms damp, clumpy crumbs.
- Scoop out 1 cup of the crumbs and set it aside for the topping.
- Press the rest of the crumbs firmly and evenly into the pan with your fingers or the bottom of a measuring cup.
- Bake the base until it is just set and lightly golden at the edges.
- Meanwhile, gently toss the raspberries with the sugar, cornstarch and lemon juice in a bowl.

- Spread the raspberry mixture over the warm base, then scatter the reserved crumbs on top, squeezing some into small clumps.
- Bake until the topping is golden and the filling bubbles thickly around the edges.
- Cool completely in the pan on a rack so the filling sets.
- Lift out by the parchment and cut into 16 bars.
