Romanian Nut Roll (Kifla) - cooking recipe

Ingredients

Dough
4 1/2 teaspoons active dry yeast (2 packets)
1/2 cup lukewarm milk
1/2 cup sugar, plus
1 teaspoon sugar
1/2 teaspoon vanilla
6 cups flour
1 cup butter
3 eggs
1 teaspoon salt
1/2 pint sour cream
Filling
1 lb walnuts, ground
1 cup white sugar
1/4 cup brown sugar
1/2 teaspoon cinnamon

Preparation

Mix ingredients for filling, set aside.
In another bowl, mix yeast, milk, 1 teaspoon sugar, and vanilla together and set aside for about 10 minutes.
In a third bowl, mix flour and 1/2 cup sugar. Cut in butter until mixture resembles course crumbs.
Add eggs, salt and sour cream, then add yeast mixture, mix and knead well until dough is shiny (about 15 minutes).
Divide into 4 balls. Roll out each ball to about 9\" x 13\" and spoon 1/4 of the nut filling over each.
Starting at the narrow end, roll dough into a loaf. Pinch the ends and fold them under. With the seam side down, let loaves rise in greased pan for 2 hours.
Brush with beaten egg and bake at 350 for 35 to 40 minutes.
