Begin by preheating your oven to 350°F (175°C). Prepare a muffin tin by lining it with paper liners or greasing each cup with butter or a non-stick cooking spray.
In a large mixing bowl, combine the pumpkin puree, vegetable oil, brown sugar, and granulated sugar. Use a whisk to mix these ingredients until the mixture is smooth and well blended.
Incorporate the eggs into the mixture one at a time, ensuring each egg is fully integrated before adding the next. Stir in the vanilla extract and mix until combined.
In a separate bowl, sift together the all-purpose flour, baking powder, baking soda, ground cinnamon, ground nutmeg, ground ginger, and salt. This step aerates the dry ingredients and enhances the flavor.
Gradually add the dry ingredients to the wet mixture, stirring gently with a spatula or wooden spoon until the batter is just combined. Avoid overmixing to keep the muffins light and fluffy.
Gently fold in the chocolate chips, making sure to reserve a handful of chips for garnishing the tops of the muffins before baking.
Evenly distribute the batter among the prepared muffin cups. Fill each cup about 2/3 full to allow space for rising. Sprinkle the reserved chocolate chips on top of the batter in each cup.
Place the muffin tin in the preheated oven and bake for 18-22 minutes. Check for doneness by inserting a toothpick into the center of a muffin; it should come out clean when they are ready.
Once baked, let the muffins cool in the pan for about 5 minutes. After that, carefully transfer them to a wire rack to cool completely.
Notes
For an extra touch of elegance, serve the muffins warm with a light dusting of powdered sugar on top.
