In a bowl, combine the chopped rhubarb with 150g granulated sugar. Let it sit for about 15-20 minutes to release some juice.

In a separate bowl, combine the flour, rolled oats, 75g brown sugar, cinnamon, and salt.

Add the cold, cubed butter to the dry ingredients. Rub the butter into the flour mixture with your fingertips until it resembles coarse breadcrumbs.

Pour the rhubarb mixture (including any released juice) into the prepared baking dish.

Evenly scatter the crumble topping over the rhubarb.

Bake for 30-40 minutes, or until the topping is golden brown and the rhubarb is bubbling around the edges.

Let the crumble cool slightly before serving. It's best served warm.
