Discovered on another site, this is a specialty recipe served at the Greenwoods Gate Bed and Breakfast Inn in Norfolk, Connecticut. I haven't yet tried it, but given my love of cranberries I know I'll be making this soon!
In a medium bowl, thoroughly whisk eggs. Slowly add the flour, whisking all the while to prevent lumps. Gradually add the milk and whisk to form a smooth batter. Set aside.
In a medium skillet, melt 2 tablespoons of butter, then add the sliced apples, cranberries, cinnamon, and sugar. Cook over medium heat until fork tender, about 15 minutes.
In a 9-inch oven-safe pie plate, melt 2 tablespoons of butter, taking care to not burn it (or spray pan with a non-stick cooking spray). Fill the plate with the cooked apple mixture, and top with the prepared batter. Bake for 15 to 20 minutes or until puffed and golden.
Top the pancake with a sprinkling of lemon juice, if desired, and finish off with a liberal dusting of powdered sugar. Slice into portions and serve immediately.
