Preheat oven to 375℉. Arrange paper liners in standard 12 count muffin pan.
In medium sized bowl, measure out flour, sugars, soda, salt and spices. Whisk dry ingredients together and set aside for now.
In a separate bowl, add eggs, pumpkin, coconut oil, and vanilla. Whisk wet ingredients together and pour into dry ingredients. Mix together just until all ingredients are incorporated. Do not over mix.
For best results, use an ice cream scoop to pour batter into each muffin liner. Batter will be evenly distributed that way.
Bake for 22-27 minutes or until toothpick inserted into center of muffin comes out clean.
Once muffins have cooled, combine glaze ingredients in small bowl. Pour glaze into small sealable plastic bag and cut one of the corners out of the bag to easily pour glaze over muffins.
