Preheat oven to 425°F (218°C). Grease or line a 12-cup muffin tin with paper liners.
In a large bowl, whisk together the flour, baking soda, cinnamon, pumpkin pie spice, ginger, and salt until well combined.
In a medium bowl, whisk the oil, granulated sugar, brown sugar, pumpkin puree, eggs, and milk until smooth.
Pour the wet ingredients into the dry ingredients and fold together with a spatula just until combined. Do not overmix.
Fill each muffin cup to the top. For taller domes, fill every other cup instead of all 12.
Bake at 425°F (218°C) for 5 minutes, then reduce the oven temperature to 350°F (177°C) and bake for an additional 16–17 minutes, or until a toothpick comes out clean.
Let the muffins cool in the pan for 5 minutes before transferring to a wire rack to cool completely.
Store cooled muffins in an airtight container lined with paper towels for up to one week at room temperature.
