Preheat oven to 375 and spray a square baking dish with nonstick spray (or use butter).
In a large bowl, mix together the dry ingredients. In another, smaller, bowl, whisk together the milk, melted butter and honey.
Pour the wet ingredients into the dry ingredients and mix until JUST combined - then fold in the berries.
Spread the mixture into your prepared pan and bake for 25-30 minutes until golden.
I prefer this cornbread after it has had some time to rest a bit --- a few hours after it's baked. Of course if you can't wait it's totally fine and delicious right away but I do find the flavor improves as it sits.
