Preheat the oven to 375°F. Line a muffin tin with liners or lightly grease it with coconut oil.
Dry Ingredients: Whisk the all-purpose flour, whole wheat flour, baking soda, cinnamon, ginger, nutmeg, and salt in a bowl.
Wet Ingredients: In another bowl, whisk the eggs, coconut sugar, coconut oil (melted and cooled slightly), pumpkin puree, and maple syrup. Add vanilla extract if using.
Fold in chocolate chips or nuts if desired.
Divide the batter evenly among the muffin cups, filling them about ¾ full.
Bake for 20-22 minutes or until a toothpick inserted into the center of a muffin comes out clean.
Cool in the tin for 5 minutes, then transfer to a wire rack to cool completely.
