Preheat your oven to 350 °F (175 °C) and line a muffin tin with paper liners.
In a large bowl, combine the pumpkin puree, sugar, vegetable oil, eggs, and vanilla extract. Mix until smooth and creamy.
In another bowl, whisk together the flour, baking soda, baking powder, cinnamon, and salt.
Gradually add the dry mixture to the wet mixture, stirring gently until just combined.
Fold in the chocolate chips, ensuring they’re evenly distributed throughout the batter.
Spoon the batter into the prepared muffin tin, filling each cup about 2/3 full.
Bake in the preheated oven for 18 to 20 minutes, or until a toothpick inserted into the center comes out clean.
Let the muffins cool in the pan for about 5 minutes before transferring them to a wire rack.
Serve warm, or store in an airtight container for up to a week.
