Whisk the dry ingredients in a bowl. Beat the wet ingredients together.
Alternately add half the liquid and half the flour mixture to the bowl while beating on low. Beat on medium for 2 minutes.
Remove the pan from the oven and allow to cool for 10 minutes. Remove the cupcakes from the pan to cool completely on a wire rack.
While cupcakes are cooling, mix the Pumpkin Spice Frosting together.
Frost the cooled Pumpkin Cupcakes with the frosting using a pastry bag and tip if desired.
Decorate the Pumpkin Cupcakes with sprinkles and a pumpkin shaped piece of candy if desired.
