Bismarck

Directions

1. 1
   Preheat oven to 400 degrees.
2. 2
   Place butter in a cast iron skillet and place in oven to melt.
3. 3
   In a large mixing bowl (or blender), combine eggs with the milk until the mixture is light yellow and not stringy, about 1 minute. Add the flour, sugar, vanilla, cinnamon and salt, and whisk vigorously to remove lumps, about 30 seconds.
4. 4
   Remove hot pan from oven. Butter should be melted. Swirl butter around the pan to coat completely, and then pour remaining butter into the batter and whisk to blend.
5. 5
   Pour the batter into the hot plan and return pan to oven.
6. 6
   Cook the pancake for about 20 mins, or until the pancake is puffed in the center, and golden brown along the edges.
7. 7
   Using a spatula, remove the entire Bismarck from the pan and place on a cooling rack for a few minutes to allow steam to escape without condensing along the bottom (otherwise bottom becomes soggy).
8. 8
   Slice the pancake into wedges on a serving platter or cutting board and serve with syrup, preserves or cinnamon sugar.
