Nut Roll Coffee Cake Recipe

In a large bowl, dissolve yeast in warm water. Add the butter, milk, egg yolks, sugar, salt and flour. Beat until smooth (mixture will be sticky). Cover and refrigerate overnight. For filling, in a small bowl, beat egg whites on medium speed until soft peaks form. Gradually beat in 1 cup sugar, about 2 tablespoons at a time, on high until sugar is dissolved. In a large bowl, combine the walnuts, milk, cinnamon and remaining sugar; fold in egg whites. Divide dough in half. On a well-floured surface, roll each portion into an 18-in. x 12-in. rectangle. Spread filling evenly over each rectangle to within 1/2 in. of edges. Roll up jelly-roll style, starting with a long side; pinch seam to seal. Place one filled roll seam side up in a greased 10-in. tube pan. Top with second roll, seam side down. Bake at 350 ° for 40-45 minutes or until golden brown. Cool for 10 minutes before removing from pan to a wire rack.
