How to Make It
Preheat your oven to 350°F (175°C).
Dump your mixed berries into a baking dish.
In a bowl, mix together the oats, flour, brown sugar, and cinnamon.
Pour the melted butter into the dry mixture and stir until crumbly.
Sprinkle the crumble over the berries evenly.
Bake for 25-30 minutes or until the top is golden and the berries are bubbling.
Serve
Let it cool slightly, then scoop warm servings into bowls. It’s great on its own or with a scoop of ice cream on top!
