How to Make It
Preheat your oven to 350°F (175°C).
Pour the mixed berries into a baking dish.
In a bowl, combine the oats, brown sugar, flour, and cinnamon.
Pour in the melted butter and mix until crumbly.
Spread the oat mixture evenly over the berries.
Bake for 25-30 minutes until golden and bubbly.
Serve
People love to scoop this warm berry crumble straight from the dish, maybe with a scoop of ice cream on the side. The juices from the berries pool at the bottom, making each bite a delicious treat.
