This recipe is amazing, great apple cinnamon flavor. I used 3 small apples. Next time, I definitely will use more. Also, I might only make half of the cinnamon swirl. It was a lot and sort of flooded the cake when I poured it on, then when I swirled it, it mixed into it. I'm making it sound bad, but trust me, it's so good, I'm just a perfectionist.
