Preheat your oven to 350°F (175°C). Prepare a muffin tin by lining it with paper liners or lightly greasing it with cooking spray.
In a large mixing bowl, combine the pumpkin puree, granulated sugar, brown sugar, vegetable oil, eggs, and vanilla extract. Using a whisk, mix these ingredients together until the mixture is smooth and fully integrated.
In a separate bowl, whisk together the all-purpose flour, baking powder, baking soda, ground cinnamon, ground nutmeg, ground ginger, and salt until well combined.
Slowly add the dry ingredient mixture to the pumpkin mixture. Gently stir until just combined, being careful not to overmix which can make the muffins dense.
Fold in the semi-sweet chocolate chips, ensuring they are evenly distributed throughout the batter without overworking it.
Using a spoon or an ice cream scoop, fill each muffin cup about three-quarters full with the batter, which allows room for rising while baking.
Place the muffin tin in the preheated oven and bake for 18-20 minutes. Check for doneness by inserting a toothpick into the center of a muffin; it should come out clean or with a few moist crumbs attached.
Once baked, remove the muffins from the oven and allow them to cool in the tin for approximately 5 minutes. Afterward, transfer them to a wire rack to cool completely.
Notes
Serve warm or at room temperature. Dust with powdered sugar or drizzle with chocolate glaze for an elegant touch.
