French Chocolate Coffee Cake

• 1 package (1/4 ounce) active dry yeast
• 2/3 cup warm water (110u0b0 to 115u0b0)
• 1/2 cup butter, softened
• 3/4 cup sugar
• 4 large egg yolks
• 1/3 cup evaporated milk
• 1/2 teaspoon salt
• 3-3/4 to 4-1/4 cups all-purpose flour
• 3/4 cup semisweet chocolate chips
• 1/3 cup evaporated milk
• 2 tablespoons sugar
• 1/2 teaspoon ground cinnamon
• 1/4 cup all-purpose flour
• 1/4 cup sugar
• 1 teaspoon ground cinnamon
• 1/4 cup cold butter, cubed
• 1/4 cup semisweet chocolate chips
• 1/4 cup chopped walnuts
• Confectioners' sugar, optional

1. In a large bowl, dissolve yeast in warm water. Add the butter, sugar, egg yolks, milk, salt and 2 cups flour; beat until smooth. Stir in enough remaining flour to form a soft dough.
2. Turn onto a floured surface; knead until smooth and elastic, about 6-8 minutes. Place in a greased bowl, turning once to grease top. Cover and let rise in a warm place until doubled, about 1 hour.
3. For filling, combine the chocolate chips, milk and sugar in a saucepan; cook and stir over low heat until smooth. Stir in cinnamon; set aside.
4. For topping, combine the flour, sugar and cinnamon in a bowl; cut in butter until crumbly. Stir in chocolate chips and nuts. Set aside.
5. Punch dough down. Turn onto a lightly floured surface; roll into an 18x10-in. rectangle. Spread with filling. Roll up jelly-roll style, starting with a long side; pinch seam to seal. Place in a well-greased 10-in. fluted tube pan, with seam facing inside of pan. Sprinkle with topping. Cover and let rise in a warm place until doubled, about 30 minutes.
6. Bake at 350u0b0 for 45-50 minutes or until golden brown. Let stand for 10 minutes before inverting onto a wire rack to cool. Sprinkle with confectioners; sugar if desired.
