Preheat the oven to 375°F and line a 12 cup muffin tin with liners.
In a bowl, sift together the flour, baking soda, baking powder, cinnamon, pumpkin pie spice, and salt. Set aside.
Whisk together the oil, granulated sugar, brown sugar, pumpkin puree, eggs, and whole milk in a bowl.
Gently fold in the dry ingredients with the wet ingredients until combined. Do NOT overmix. Mix in the chocolate chip morsels.
Using 1/3 measuring cup, scoop the muffin batter into the muffin tins, evenly dividing the liners. Make sure you don't over fill the muffin liners, fill up to about 2/3 full.
Bake the muffins at 375°F for 20-25 minutes or until toothpick runs clean through the muffins. Remove and allow to cool on a cooling rack.
