Preheat the Oven and Prepare the Muffin Tin
Preheat your oven to 350°F (175°C) and line a 12-cup muffin tin with paper liners or lightly grease it.
Mix Dry Ingredients
In a large bowl, whisk together the flour, baking soda, baking powder, salt, cinnamon, nutmeg, and ginger. Set aside.
Mix Wet Ingredients
In another bowl, combine the pumpkin puree, eggs, vegetable oil, sugar, and vanilla extract. Use a whisk or a hand mixer to beat until the mixture is smooth and well combined.
Combine Wet and Dry Ingredients
Gradually add the dry ingredients to the wet ingredients, stirring until just combined. Avoid overmixing, as it can result in dense muffins.
Add Optional Ingredients
If you’re using chocolate chips, nuts, or any other add-ins, fold them into the batter now.
Fill Muffin Tin
Evenly divide the muffin batter among the 12 muffin cups, filling each cup about 2/3 full.
Bake
Bake for 18–22 minutes, or until a toothpick inserted into the center of a muffin comes out clean. Be sure to check, as oven temperatures can vary
Cool and Serve
Allow the muffins to cool in the tin for 5 minutes before transferring them to a wire rack to cool completely
