Toss 3 sliced peaches with 1 tablespoon brown sugar and 1/2 teaspoon vanilla extract; set aside until juicy, about 30 minutes. Whip 1 cup heavy cream until it thickens, then beat in 4 teaspoons brown sugar. Add 4 teaspoons bourbon and beat until soft peaks form. Layer the peaches and cream in dessert glasses; top with toasted pecans.
