Blackberry cobbler

With fresh blackberries from my mom's backyard, right off the vine.

3 cups blackberries
1 cup sugar
1 cup flour
2 teaspoons baking powder
1/2 teaspoon salt
1 cup milk
1/2 cup butter, melted

Stir together the blackberries and sugar, and let sit for a few minutes. Meanwhile, stir together the flour, baking powder, salt and milk. Add the melted butter and combine. Pour into an ungreased 8 x 8 pan, and spoon the blackberry mixture over the batter. Bake at 375 for 45-55 minutes, or until the batter is puffy and golden.
