A delightful dessert combining the sweetness of mixed berries with a crispy oat topping.
Preheat your oven to 375°F (190°C).
Ensure the oven is fully preheated for even baking.
In a mixing bowl, combine the blueberries, raspberries, cherries, brown sugar, flour, and lemon juice. Mix gently to coat the berries evenly.
Mix gently to avoid crushing the berries.
Transfer the berry mixture into an 11 x 7-inch baking dish, spreading it out evenly.
Use a spatula to spread the mixture evenly.
In another bowl, combine the flour, brown sugar, oats, and cinnamon. Cut in the butter using a pastry blender until the mixture resembles coarse crumbs.
Ensure the butter is cold for a crumbly texture.
Sprinkle the topping evenly over the berry mixture in the baking dish.
Distribute the topping evenly for a uniform crust.
Bake in the preheated oven for 30 minutes, or until the topping is golden brown and the filling is bubbly.
Place the dish on a baking sheet to catch any drips.
Let the crumble cool slightly before serving. Serve warm with a scoop of vanilla ice cream or whipped cream.
Allowing it to cool slightly helps the filling set.
