Heat oven to 325 F. Peel, pit and thinly slice peaches. Grease a 10.5-inch cast iron skillet, and arrange peaches in the bottom. Sprinkle pecans over the peaches.
In a small bowl, melt 1/2 cup butter, and mix in the brown sugar. Pour mixture over the peaches and pecans.
Melt the remaining 1/2 cup butter and add to a large bowl with the cake mix, milk, eggs and cinnamon. Mix well.
Pour cake batter over the peaches and brown sugar mixture.
Bake 45 to 50 minutes or until a toothpick inserted in the center comes out clean. Immediately cover pan with a platter and invert. Serve warm. Top with whipped cream or ice cream, if desired.
