01 - Preheat oven to 350°F (175°C). Line mini muffin pans with paper liners or lightly grease each well.
02 - Whisk together flour, baking soda, baking powder, salt, cinnamon, and nutmeg in a medium bowl until well combined.
03 - In a large mixing bowl, beat eggs lightly, then stir in pumpkin puree, granulated sugar, brown sugar, vegetable oil, and vanilla extract until smooth.
04 - Gradually add the dry ingredients to the wet mixture, folding gently until just incorporated. Do not overmix.
05 - Gently fold chocolate chips into the batter until evenly distributed.
06 - Spoon batter into prepared mini muffin cups, filling each about three-quarters full. Bake for 12 to 15 minutes until a toothpick inserted in the center comes out clean or with a few moist crumbs.
07 - Allow muffins to cool in the pan for 5 minutes, then transfer to a wire rack to cool completely before serving.
