Preheat oven to 350°F (175°C). Line a muffin tin with cupcake liners.
In a mixing bowl, combine pumpkin puree, sugar, vegetable oil, and eggs. Mix until smooth.
In another bowl, whisk together flour, baking powder, baking soda, salt, cinnamon, ginger, and cloves.
Gradually add the dry ingredients to the wet ingredients, mixing until just combined.
Divide the batter evenly among the cupcake liners, filling each about two-thirds full.
Bake for 20 minutes or until a toothpick inserted into the center comes out clean. Let cool completely before frosting.
