Preheat oven to 350 degrees.
Grease a muffin tin or line with liners.
Whisk together egg, brown sugar, maple syrup, vanilla and pumpkin.
In a separate bowl, whisk together flours, baking soda, baking powder, salt and cocoa powder. Mix into wet ingredients. Fold in chocolate chips.
If desired, top with additional chocolate chips (and really, why wouldn't you?).
Bake at 350 for 24-25 minutes or until toothpick inserted in the middle of a muffin comes out clean.
Cool in pan for five minutes before transferring to a wire rack.
