How to Make It
Preheat your oven to 350°F (175°C).
Spread the mixed berries evenly in a baking dish.
In a bowl, combine oats, brown sugar, flour, and cinnamon.
Pour the melted butter over the oat mixture and stir until combined.
Sprinkle the crumble mixture over the berries in the baking dish.
Bake for 25-30 minutes until the top is golden and the berries are bubbly.
Serve
Enjoy warm, spooning it directly from the dish. It pairs perfectly with a scoop of vanilla ice cream or whipped cream on top!
