Preheat oven to 375°F (190°C). Line a 12-cup muffin tin with paper liners or grease it well.
In a large bowl, whisk together the flour, baking soda, cinnamon, nutmeg, cloves, and salt. Set aside.
In a separate large bowl, beat together the sugar and eggs until well combined. Stir in the pumpkin puree and vegetable oil until smooth. Then, stir in the milk.
Gradually add the dry ingredients to the wet ingredients, mixing until just combined. Do not overmix.
Gently fold in the chocolate chips.
Divide the batter evenly among the prepared muffin cups, filling each about two-thirds full.
Bake for 18-22 minutes, or until a toothpick inserted into the center of a muffin comes out clean.
Let the muffins cool in the tin for a few minutes before transferring them to a wire rack to cool completely.
Notes
These muffins are best enjoyed fresh but can be stored in an airtight container at room temperature for up to 3 days.
