Preheat oven to 400 degrees Fahrenheit. Grease a 12-cup muffin pan or line with paper liners.
In a medium bowl, whisk together sugar, eggs, and oil until combined. Stir in pumpkin and water until well combined.
In a large bowl, whisk together flour, baking powder, baking soda, cinnamon, nutmeg, cloves, and salt.
Pour pumpkin mixture into flour mixture and stir until just combined — do not overmix. Fold in chocolate chips.
Divide batter evenly among muffin cups, filling each about two-thirds full. Press extra chocolate chips into the tops.
Bake 20 to 25 minutes until a toothpick inserted in the center comes out clean.
Cool in pan a few minutes, then transfer to a wire rack.
