Pre-heat oven to 350° F, and grease or line your muffin tins.
Mix together the butter and sugar.
Then mix in the eggs, vanilla extract, and pumpkin.
In a separate mixing bowl, whisk together the dry ingredients, including the flour, salt, baking soda, baking powder, pumpkin pie spice, and ground cloves.
Then just mix the dry ingredients into the wet ingredients.
Scoop the batter into prepared muffin tins.
Sprinkle the top of each muffin with a little bit of cinnamon sugar.
Bake the muffins at 350° F for about 25 minutes, or until a cake tester or toothpick inserted into the center comes out clean.
Allow the muffins to cool in the muffin tins for about 10 minutes.
Then remove them to a wire rack to finish cooling.
Serve with butter and enjoy!
