Pre-heat oven to 350 degrees. Melt butter in 9x13 inch baking dish while oven is pre-heating. Mix together all dry ingredients plus milk. Take baking dish out of oven with melted butter. Pour batter mixture over butter, then pour peaches over batter. Place back in oven and bake for 35-40 minutes, or until top is browned. Let cool slightly, then serve with vanilla ice cream. Enjoy!
