Preheat your oven to 350°F (175°C) and line a muffin tin with paper liners.
In a large bowl, whisk together the pumpkin puree, vegetable oil, and sugar.
Add the eggs one at a time, mixing well after each addition.
In another bowl, combine the flour, baking soda, baking powder, cinnamon, nutmeg, and salt.
Gradually add the dry ingredients to the wet mixture, stirring until just combined.
Scoop the batter into the prepared muffin tin, filling each cup about 2/3 full.
Bake in the preheated oven for 20-25 minutes, or until a toothpick inserted comes out clean.
Remove from the oven and let cool in the tin for 5 minutes.
Transfer muffins to a wire rack to cool completely.
Enjoy your delicious pumpkin muffins fresh or store for later!
