German Pancakes

I have no idea if this is an authentic German recipe.

When Jess was young, her and her brothers and sisters would watch through the oven door window with great anticipation to see these pancakes rise.

6 eggs
1 cup flour
1 cup milk
1/2 tsp salt
1/2 cube butter

I mix it in a blender. Beat the eggs. Mix in everything else except the butter. Melt the butter and tilt it around the pan to coat the bottom. Pour in the batter. Bake at 425 for approximately 20 min. My family always eats this with lemon juice and powdered sugar. Jess's family put it in a bowl and puts milk and granulated sugar on it.
