Chocolate Coffee Cake

Directions

1. In a large bowl, dissolve yeast in water; let stand for 5 minutes. Add butter, sugar, egg, salt and milk powder; mix well. Add 2 cups flour; beat until smooth. Stir in enough remaining flour to form a soft dough.
2. Turn onto a floured surface and knead until smooth and elastic, about 6-8 minutes. Place in a grease bowl, turning once to grease top. Cover and let rise in a warm place until doubled, about 1 hour.
3. For filling, combine chocolate chips, milk and sugar in a saucepan; cook and stir over low heat until smooth. Stir in cinnamon; set aside. For topping, combine flour, sugar and cinnamon in a bowl; cut in butter until mixture resembles coarse crumbs. Set aside.
4. Punch the dough down; roll into a 20x10-in. rectangle. Spread with filling. Roll up, jelly-roll style, starting with a long side; seal seam. Place in a well-greased 10-in. fluted tube pan, with seam facing the inside of the pan. Sprinkle with topping. Cover and let rise in a warm place until doubled, about 30 minutes.
5. Bake at 350° for 45-50 minutes or until golden brown. Let stand for 10 minutes; invert onto a wire rack to cool.
