Combine pumpkin, brown sugars, milk, oil, egg and vanilla in a large bowl; stir to blend. Add flour, baking powder, cinnamon, nutmeg and salt; stir until just combined. Scoop heaping tablespoons into prepared muffin cups.
Bake 11-12 minutes or until toothpick inserted into centers comes out clean. Cool in pans 5 minutes. Remove to wire rack.
