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, applesauce, maple syrup (or honey), melted coconut oil, eggs, and vanilla extract. Whisk until smooth and creamy.
In another bowl, whisk together the whole wheat flour, baking soda, baking powder, pumpkin pie spice, and salt until well mixed.
Gradually incorporate the dry ingredients into the wet mixture, stirring gently until just combined.
If desired, fold in the chopped walnuts or pecans and dark chocolate chips.
Evenly distribute the batter among the muffin cups, filling each about three-quarters full.
Bake in the preheated oven for 18-22 minutes until a toothpick inserted comes out clean.
Allow the muffins to cool in the pan for 5 minutes before transferring them to a wire rack to cool completely.
Notes
Display the muffins on a charming platter and sprinkle a light dusting of cinnamon on top for an inviting, seasonal touch.
