Meanwhile, pat peaches dry, and coarsely chop. Melt 2 tablespoons butter in 10-inch nonstick skillet over medium-high heat. Add peaches, and cook 6 to 8 minutes, stirring frequently, until softened and beginning to brown on edges. Stir in 2 tablespoons of the brown sugar, the vanilla and cinnamon. Continue to cook 30 to 60 seconds, stirring constantly, until sugar melts. Transfer to medium bowl; cover and refrigerate until cooled, about 1 hour.
