Preheat oven to 350°F and grease a muffin tin.
Mix the milk and vinegar in a small bowl and set aside.
Mix the flour, salt, baking soda, baking powder, cinnamon, nutmeg and cloves in a mixing bowl and set aside.
Add the sugars, pumpkin purée, oil, vanilla and milk mixture to a large mixing bowl. Mix until smooth. Add in the flour mixture and mix until just combined.
Evenly distribute the batter into the muffin tin, filling all 12 cavities.
Bake for 20-24 minutes, until a toothpick comes out clean or with only crumbs.
Allow to cool slightly and serve! These are delicious plain or with a bit of vegan butter or pumpkin butter.
