In a bowl, combine the flour, pumpkin pie spice, baking soda and salt.
In a second bowl, combine the pumpkin puree, brown sugar, eggs, oil, maple syrup and vanilla; mix well.
Stir the wet ingredients into the dry ingredients just until moistened.
Fold in chocolate chips and pecans.
Fill greased or paper-lined muffin wells ½ to ¾ full. A silicone muffin pan also works great.
Bake at 375°F for 17-21 minutes or until toothpick inserted in the center comes out clean.
Cool for 10 minutes; remove from pan to a wire rack to cool completely.
