How to Make It
Preheat your oven to 350°F (175°C).
Spread the mixed berries evenly in a greased baking dish.
In a bowl, whisk together the flour, sugar, baking powder, and salt.
Add the milk, melted butter, and vanilla extract to the dry ingredients and stir until combined.
Pour the batter over the berries in the baking dish.
Bake for 30-35 minutes, or until the top is golden brown and the berries are bubbling.
