Add eggs and beat with an electric mixer at medium speed for one minute. Add flour, salt, baking powder, milk, and vanilla extract, beat at medium speed for one minute.
Spoon batter evenly into cupcake liners. Bake for 18-20 minutes or until the centres spring back when touched and cupcakes are very lightly browned.
Let cool in the pan on a rack for five minutes. Remove cupcakes from pan onto a rack and cool completely.
Using a teaspoon scoop out a small hole in the center of each cupcake, then fill with the apple pie filling.
FOR THE FROSTING:
Add softened butter and vanilla to the mixing bowl and mix until completely combined.
Add powdered sugar and cinnamon and beat on low until it is incorporated, then move the mixer up to medium-high speed. Scrape sides and bottom of bowl often.
When completely mixed the frosting may appear dry so add the milk a little at a time until frosting is the proper consistency.
Frost each cupcake using a piping bag.
