In a saucepan, heat milk to 180 degrees F. Add sugar and shortening and continue heating until shortening is melted. Allow liquid to cool slightly. Overheating will kill the yeast and prevent your dough from rising.
In a large mixing bowl, combine only 4 cups of the bread flour and remaining dough ingredients. Combine with warm milk mixture. Mix well. Add 4 eggs, one at a time, mixing well after each addition. Add additional flour one cup at a time until dough is sticky but manageable (additional 4-5 cups). You don’t want it dry and tough. Cover and allow the dough to rise in a warm non-drafty area 1 to 1-1/2 hours. Punch down and allow to rise again for approximately 1 hour.
Spray 3-9x13 pans with non-stick cooking spray.
On a floured surface, roll dough out until 12 to 14 inches wide and 3 feet long and 1/2 inch thick. Brush with melted butter and sprinkle on sugar, chocolate malted milk powder and chocolate chips, cover dough. Roll dough evenly and slightly tight toward you. Cut into 1-inch rolls with a sharp knife or dental floss.
Preheat oven to 350 degrees F. Spray 3-9x13 pans with non-stick cooking spray.
Put 12 rolls in each pan. Cover and allow to rise 1 hour.
Bake at 350 degrees F for 20 minutes. Remove pan from oven and allow to cool for 5 minutes. Turn rolls out of their pan onto a piece of tin foil or serving platter. Allow the rolls to cool for 10 additional minutes while you prepare the glaze.
Drizzle or frost with glaze.
Store in airtight container for up to a week, or place in the freezer for up to 3 months.
