In a large saucepan, combine all the peaches and 3/4 cup of the sugar. Cook over medium heat, until sugar dissolves and the juice is slightly thickened. About 8-10 minutes.
In a large bowl, whisk together the flour, remaining 1 cup of sugar, baking powder, and salt. Then, add in the milk and mix together thoroughly.
Place the butter in a baking dish and set it in the oven. Preheat the oven to 350 degrees and let the butter melt in the dish. About 5-8 minutes. Take out the dish once the butter has melted fully.
Pour the mixed batter on top of the melted butter in the baking dish. Spoon the peaches and the juices on top of that. Then, sprinkle the ground cinnamon on top.
Bake until the center comes out clean with a toothpick, about 35 minutes. Serve warm with vanilla ice cream on top and enjoy!
