Preheat the oven to 375? F. Drop the butter into a 9?13 inch baking dish and place the dish in the oven to melt, about 10 minutes.

In a bowl, stir together the flour, 3/4 cup brown sugar, baking powder, cinnamon, and salt. Add the milk and vanilla, and mix until just combined.

In another bowl, toss the peaches with 1/4 cup brown sugar and the maple syrup.

Layer half of the peaches over the melted butter. Then, pour over the batter, do not stir. Layer the remaining peaches over the batter.

Bake for 50-55 minutes, until the center is just set and the edges begin to brown.

Meanwhile, mix the butter and maple syrup in a pan. Boil for 2 minutes, then remove from the heat.

Serve the cobbler warm or at room temperature with ice cream and drizzle the maple butter on top.
