How to Make It
Preheat your oven to 350°F (175°C).
In a large bowl, combine the mixed berries and sprinkle a bit of sugar over them.
In another bowl, mix the oats, flour, brown sugar, and cinnamon.
Pour the melted butter into the oat mixture and stir until crumbly.
Spread the berry mixture in a baking dish and top with the crumble mixture.
Bake for 30 minutes or until golden brown and bubbly.
Serve
Let it cool for a few minutes, then scoop it into bowls. Perfect on its own, or serve with a scoop of ice cream for a treat!
