Preheat the oven to 350°. Spray a standard 12-cup muffin tin with cooking spray. In a large bowl, whisk the flour with the sugar, baking powder and salt. In a large measuring cup, whisk the milk with the oil, eggs and vanilla. Fold the egg mixture into the dry ingredients just until incorporated; do not overmix. Gently fold in the raspberries, dried peaches and candied ginger.
