Preheat the oven to 425°F and prepare a muffin tin with paper liners.
In a bowl, whisk together the flour, baking soda, salt, pumpkin pie spice, and cinnamon.
In a separate bowl, stir the pumpkin puree, granulated sugar, brown sugar, eggs, oil, and vanilla until smooth.
Gently fold the dry ingredients into the wet mixture just until combined.
In a small bowl, whisk the cream cheese with powdered sugar until creamy.
Scoop pumpkin batter into each muffin cup until halfway full, add a dollop of cream cheese, then cover with more batter.
Bake at 375°F for 20-25 minutes, until the muffins are domed and a toothpick comes out clean.
