Preheat the oven to 400 degrees.
In a blender or with a hand mixer, combine all the ingredients except the butter until the batter is a bit frothy, about 2 minutes on high speed. You may have to stop and scrape some of the flour from the sides of the blender, if you are using that method.
Place 1 Tablespoon of butter in each pie pan. When the oven reaches 400 degrees, place the pans in the oven until the butter is melted, about 2 minutes. Then, remove the pans from the oven and brush the bottom of the sides of the pan.
Add one half of the batter to each pan, then quickly return to the oven. Cook for about 18 minutes at 400 degrees, Then, reduce the heat and cook another 4 to five minutes. Don't open the oven as the chocolate German pancakes are cooking.
Remove both German chocolate pancakes from the oven. You may notice they have puffed up a bit, which is normal. They will deflate shortly after you remove them from the oven.
Slice the German chocolate pancakes as you would a pie. Add optional toppings such as butter, powered sugar, chocolate sauce, or maple syrup.
