Chocolate Cinnamon Rolls (Adopted)

I love to make this in the morning for my kids.

• Ready In: 1 hr
• Serves: 16

Ingredients

• 1⁄4 ounce dry yeast
• 2  tablespoons sugar
• 1 1⁄4 cups skim milk, warmed (105 To 115F)
• 1⁄4 cup margarine, melted
• 1⁄2 teaspoon vanilla extract
• 1  egg, lightly beaten
• 4  cups bread flour, divided
• 1⁄3 cup  unsweetened cocoa
• 1⁄2 teaspoon salt
•  vegetable oil cooking spray
• 1  egg white, lightly beaten
• 1⁄4 cup sugar
• 1  teaspoon ground cinnamon
• 1  cup  sifted powdered sugar
• 2  tablespoons skim milk
• 1  teaspoon vanilla extract

Directions

1. Dissolve yeast and 2 tablespoons sugar in 1 1/4 cups warm milk in a large bowl; let stand 5 minutes.
2. Add margarine, 1/2 teaspoon vanilla, and egg; stir well.
3. Stir in 3 1/2 cups flour, cocoa, and salt to form a soft dough.
4. Turn dough out onto a lightly floured surface, and knead until smooth and elastic (about 10 minutes); add enough of the remaining flour, 1 tablespoon at a time, to prevent dough from sticking to hands.
5. Place dough in a large bowl coated with cooking spray, turning to coat top.
6. Cover and let rise in a warm place (85F), free from drafts, 45 minutes or until doubled in bulk.
7. Punch dough down.
8. Turn out onto a lightly floured surface; roll into a 16 x 8 inch rectangle.
9. Brush egg white over entire surface.
10. Combine 1/4 cup sugar and cinnamon; sprinkle evenly over dough.
11. Starting at long side, roll up dough tightly, jelly-roll fashion; pinch seam to seal (do not seal ends of roll).
12. Cut roll into 16 (1-inch) slices, using string or dental floss.
13. Arrange slices, cut sides up, in a 13 x 9 inch baking pan coated with cooking spray.
14. Cover and let rise 30 minutes or until doubled in bulk.
15. Preheat oven to 350F; bake rolls at 350F for 20 minutes.
16. Combine powdered sugar, 2 tablespoons milk, and 1 teaspoon vanilla; stir well.
17. Drizzle over rolls.
