Preheat the oven to 375°F (190°C).
Line a 12-cup muffin tin with paper liners or lightly grease the cups.
In a medium bowl, whisk together the flour, baking soda, baking powder, salt, pumpkin pie spice, and cinnamon.
In a large bowl, whisk together the eggs, pumpkin puree, brown sugar, granulated sugar, vegetable oil, and vanilla extract until smooth.
Gradually add the dry ingredients to the wet ingredients and stir until just combined. Do not overmix.
Divide the batter evenly among the prepared muffin cups, filling each about three-quarters full.
Bake for 18 to 22 minutes, or until a toothpick inserted into the center comes out clean.
Allow the muffins to cool in the pan for 5 minutes before transferring them to a wire rack.
Serve warm or at room temperature.
