In a large bowl, dissolve yeast in water. Let stand 5 minutes. Stir in butter, sugar, eggs, salt and 3 cups flour. Add enough remaining flour to form a soft dough. Turn out onto a floured surface; knead until smooth and elastic, about 6-8 minutes. Place dough in a greased bowl, turning once to grease top. Cover and refrigerate 2 hours. Meanwhile, combine all filling ingredients in a saucepan. Bring to boil; reduce heat and cook until thickened, stirring constantly. Cool. Turn dough out onto a lightly floured surface. Roll out to make a 14-inch by 16-inch rectangle. Spread with filling. Roll up, jelly roll-style, beginning with the long end. Cut into 12 slices. Place, cut side down, on a greased 13-inch by 9-inch baking pan. Cover and let rise until almost doubled, for about 25 minutes. Bake at 375° for 25 minutes or until golden brown. Remove from pan; cool slightly. Combine all icing ingredients; drizzle over warm rolls. Serve immediately.
