Preheat your oven to 350°F (175°C) and line a muffin tin with paper liners or grease it with cooking spray.
In a mixing bowl, combine the pumpkin puree, cream cheese, and sugars. Beat until smooth and well combined.
Add the eggs, one at a time, mixing well after each addition.
In another bowl, whisk together the flour, baking soda, cinnamon, and any other spices you choose to use.
Gradually add the dry ingredients to the wet ingredients, stirring gently until just combined. Avoid overmixing.
Fill each muffin cup about 2/3 full with batter.
Bake in the preheated oven for 20-25 minutes, or until a toothpick inserted in the center comes out clean.
Once baked, allow the muffins to cool in the tin for 5 minutes before transferring them to a wire rack to cool completely.
