This has been a favourite weekend breakfast of ours since our children were in elementary school.
It is baked in the oven so there is no need to stand and flip pancakes while everyone else is eating. You could call it an "Upside Down Pancake" It looks amazing and is so tasty with the caramelized apples. Cut into wedges, it will serve 6-8 people depending on the size of your pan.
Note: This past weekend I tried this with blueberries and it was terrific. I melted the butter and brown sugar together in the cast iron skillet and then sprinkled fresh blueberries on top before adding the pancake batter and baking. I'm sure frozen berries would work just as well.
