Preheat oven to 350°F (175°C) and line a 12-cup muffin pan with paper liners.
In a bowl, combine flour, baking soda, baking powder, salt, and spices. Set aside.
In another bowl, whisk pumpkin puree, granulated sugar, brown sugar, oil, eggs, and vanilla.
Add dry ingredients to wet ingredients and stir until just combined.
Fold in chocolate chips gently.
Divide batter evenly into the muffin cups.
Bake for 18–22 minutes or until a toothpick inserted into the center comes out clean.
Cool for 5 minutes in the pan, then transfer to a wire rack to finish cooling.
