Preheat oven to 350 degrees F. Line two 12-cup muffin tins with paper muffin cups or grease with non-stick spray.
In a medium bowl, combine flour, sugar, cinnamon, ginger, cloves, nutmeg, baking soda, baking powder and salt. Whisk together, then set aside.
In a separate large bowl, combine the eggs, pumpkin and melted butter. Beat on low speed until just combined. Gradually beat in the dry ingredients, just until moistened. Do not over mix.
Stir in the white chocolate chips. Scoop batter into the muffin tins 2/3 full. Bake 18 to 20 minutes, or until toothpick inserted in center comes out clean. Cool muffins in tins.
