Preheat your oven to 350°F (175°C) and line a muffin tin with paper liners.
In a large bowl, whisk together the pumpkin puree, eggs, sugar, and vegetable oil until smooth.
In a separate bowl, mix the dry ingredients: flour, baking soda, pumpkin pie spice, and a pinch of salt.
Gradually add the dry ingredients to the pumpkin mixture, gently stirring until just combined. Do not overmix!
Fold in the chocolate chips until evenly distributed throughout the batter.
Divide the batter evenly among the muffin cups, filling each about two-thirds full.
Bake in the preheated oven for 18-20 minutes or until a toothpick inserted into the center comes out clean.
Let the muffins cool in the tin for about 5 minutes before transferring them to a wire rack to cool completely.
