Preheat oven to 400ºF (Make sure that the oven rack is in the center spot.)
Put a 12-inch cast iron skillet in the oven as it is heating.
In a Nutri-Bullet® or blender, blend together the eggs, milk, flour, vanilla and 2 Tablespoons of the sugar until well mixed. Set aside.
In a medium bowl mix together the remaining 2 Tablespoons sugar, cinnamon, nutmeg and salt.
Peel and core the apples then slice into ⅛" slices.
Put the apple slices into the cinnamon mixture and toss until well coated.
When oven is heated, remove the skillet and add the butter. Let it sizzle and melt. (It's okay if it browns a little.)
Then add the sliced apple mixture and stir until all the apples are well coated with the butter.
Push the apples away from the edge of the skillet so there is about a 1-inch clearance between the apples and the edge of the pan.
Pour the batter into the skillet around and over the apples.
Sprinkle the berries on top.
Return to oven and bake for 20-25 minutes.
When done, place skillet on cooling rack for about 10 minutes then slice and serve with the Ricotta Cream and Cinnamon Sugar.
