APPLE CUPCAKES from Cupcake Project

This recipe is from Cupcake Project and it's excellent. I recommend it highly. I made half and got 8 using 1/4 c. batter per cupcake. They baked in 17 minutes. I omitted all spices except cinnamon. The recipe doesn't call for salt so I added 3/8 t. but it needs more. I used one large apple, finely diced. I made my own thick glaze for this. 

Edit- I made half the recipe twice since the first time, using milk in place of the 1/4 c. sour cream and 1/2 t. fine salt and they turned out great!
