Preheat your oven temperature to 425°F (218°C). Then, grease your muffin pan with non-stick cooking spray or line it with paper liners!
Mix the flour, cinnamon, baking soda, ginger, pumpkin pie spice, and salt in a big bowl until creamy. Set that bowl aside for a second.
Mix the oil, brown sugar, granulated sugar, eggs, pumpkin puree, and milk in another bowl until combined. Pour this mixture into your bowl of dry ingredients (from Step 2). Gently fold everything in until you have a smooth batter without flour pockets!
Grab your muffin liners and fill them with the pumpkin muffin batter you just made.
Let them bake in the preheated oven for about 5 minutes. Then, dial the baking temperature to 350°F (177°C) and keep baking for another 16 to 20 minutes until a toothpick stuck in the middle comes out mostly clean 21 to 26 minutes in total)
Let them rest in the pan for about 5 minutes before you dig in. Enjoy!
