Preheat oven to 350 degrees F. Add 12 cupcake liners to a cupcake pan and set aside.
Add eggs, sugar, applesauce, and vanilla extract to the bowl of an electric mixer. Mix on medium until combined.
In a small bowl, add flour pumpkin pie spice, baking powder, baking soda and salt. Whisk to combine. Add dry ingredients to the mixing bowl and mix on low until combined.
Use a cookie scoop to fill each cupcake liner halfway full with the batter. There should be enough batter for exactly 12 cupcakes.
Bake for 18-21 minutes or until a toothpick inserted in the center of a cupcake comes out clean. Allow cupcakes to cool to room temperature before frosting.
For the Cream Cheese Frosting:
Add softened cream cheese, butter, vanilla extract and pumpkin pie spice to the bowl of a mixer. Mix until ingredients are combined.
Add 1 cup of powdered sugar to the mixing bowl at a time, mixing until incorporated. Repeat this process until all 4 cups of powdered sugar have been added to the frosting.
Frost cupcakes once cooled, and top with a light sprinkle of pumpkin pie spice if desired.
Notes
Notes: These cupcakes are best stored in the refrigerator and consumed within 3-4 days, though they may last up to a week when stored in an airtight container.
