Streusel Kuchen - cooking recipe

Ingredients

2 cups milk
1/2 cup butter
1 cup sugar
1/2 teaspoon salt
1 egg, separated
6 1/2 cups flour, sifted
1 cake yeast, softened in
1/3 cup water (lukewarm)
butter, melted
brown sugar
Streusel
1 cup sugar
2 teaspoons cinnamon
1/2 cup flour, sifted
3 tablespoons butter, softened
1/2 teaspoon vanilla
6 tablespoons nuts, minced

Preparation

To make streusel: Mix sugar, cinnamon and flour together; cut in butter to make fine crumbs. Add vanilla and nuts.
Cream butter, sugar, salt and egg yolk.
Add milk alternately with flour and the softened yeast cake.
Beat well and add stiffly beaten egg white; cover and allow to rise overnight.
Add just enough flour to allow handling; roll pieces of dough into flat cakes, large enough to fit piepans.
Spread on well-greased pie pans, cover and let rise until doubled.
Brush melted butter over top and spread with streusel OR sprinkle thickly with brown sugar instead.
Bake at 400F about 20 minutes.
