Bake at 350°F for 20-22 minutes or until a toothpick inserted into the middle of a center cupcake comes out clean.
Allow cupcakes to cool completely before frosting.
Make Cinnamon Cream Cheese Frosting
Place softened cream cheese and butter into a large mixing bowl. Using either a stand mixer fitted with a paddle attachment or an electric handheld mixer, cream them together on medium-high until smooth, creamy, and lump-free (about 2 minutes).
Mix in cinnamon, vanilla extract, and salt until combined.
On low speed, slowly mix in sifted powdered sugar until completely combined. Then, turn mixer on medium-high and mix for 2 more minutes.
Optional: Once cupcakes are completely cooled, you can fill the centers of each cupcake with frosting by using a piping bag fitted with a filling tip.
Add frosting to the tops of the cooled cupcakes anyway you'd like. I prefer to use a piping bag fitted with a large star tip.
