Preheat the oven to 350℉. Add paper cupcake liners to the cupcake pan.
In a medium sized bowl, add the flour, pumpkin pie spice, cinnamon, salt, baking powder, and baking soda. Whisk to blend thoroughly. Set aside.
In the bowl of your electric mixer (using paddle attachment if using a stand mixer), add softened butter and sugar. Mix for 3-5 minutes, until lightened in color and fluffy.
Next, add the eggs, one at a time, mixing after each until the yellow of the yolk has blended in.
Add the canned pumpkin and vanilla. Mix on low speed to blend.
With the mixer on low speed, and beginning and ending with the flour mixture, add the flour mixture alternately with the milk. We did a total of three additions of the flour mixture and two additions of the milk. Mix just until incorporated. Makes approximately 7.5 cups of cake batter. Scoop the pumpkin cake batter into the paper liners. We use a ¼ cup scoop for this. This recipe will make about 30 or so cupcakes.
Bake at 350℉ for 15-18 minutes. They are done when an inserted toothpick comes out clean or with just a few moist crumbs attached. The centers should also spring back when lightly touched.
After removing the cupcake pans from the oven, remove the cupcakes so that they will not continue to bake. We like to sit them on cooling racks for even cooling.
