Preheat the oven to 350 degrees. Either grease the pans or use muffin wrappers.
In a large bowl, mix together the pumpkin, oil, sugar and eggs.
Combine the flour, baking powder, baking soda, salt, cinnamon, nutmeg and cloves. Stir the dry ingredients into the pumpkin mixture until well blended. Divide the batter evenly between the prepared pans.
Bake in preheated oven for 17 minutes for mini muffins, 30 minutes for regular size muffins or an hour for a loaf of bread.
Top with powdered sugar and ENJOY!
