01 - Preheat the oven to 175°C.
02 - In a large mixing bowl, combine the pitted and halved cherries with granulated sugar and lemon juice. Toss gently to coat, then transfer mixture into a greased 20-centimeter square baking dish.
03 - In a separate bowl, stir together rolled oats, all-purpose flour, brown sugar, cinnamon, and salt. Add melted butter and mix until the topping forms coarse, crumbly clusters.
04 - Evenly distribute the oat crumble over the prepared cherry filling in the baking dish.
05 - Bake for 30 minutes, until the topping is golden brown and the cherry filling is bubbling.
06 - Allow to cool slightly before serving for best texture.
