How to Make It
Preheat your oven to 350°F (175°C).
Spray a baking dish with non-stick cooking spray.
Spread the mixed berries evenly in the bottom of the dish.
In a bowl, combine the flour, sugar, baking powder, and salt.
Add the milk, melted butter, and vanilla to the dry ingredients, mixing until smooth.
Pour the batter over the berries, spreading it evenly.
Bake for 30-35 minutes until golden brown and a toothpick comes out clean.
