Preheat your oven to 350°F. Grease muffin tins to prepare for the batter.
In a stand mixer, or large mixing bowl, cream the sugar, butter, and eggs together.
Add the pumpkin puree to the mixture.
Add in the flour, baking soda, salt, baking powder, cinnamon, and pumpkin spice to the mixture and mix it on a low speed.
Add the water and mix. Gently fold in the chocolate chips.
Add the pumpkin muffin batter to the muffin tins, filling ¾ of each muffin section. Leave some room for the muffins to rise.
Bake for 20 minutes, or until a toothpick comes out clean when inserted into the middle of a muffin.
