Prepare the Dough:

1. Activate the Yeast: In a small bowl, warm the milk until it’s just warm to the touch (about 110°F). Add the sugar and yeast, stirring gently. Let it sit for 5-10 minutes, or until the mixture is frothy.
2. Mix Dry Ingredients: In a large bowl, whisk together the flour, salt, cocoa powder, and red food coloring.
3. Combine Wet Ingredients: In another bowl, whisk together the eggs, softened butter, and vanilla extract.
4. Make the Dough: Pour the yeast mixture and the wet ingredients into the flour mixture. Stir until combined and a dough forms. Knead the dough for 5-7 minutes until smooth and elastic.
5. Let it Rise: Place the dough in a greased bowl, cover with a clean towel, and let it rise in a warm place for 1-2 hours, or until it has doubled in size.

Make the Cinnamon Filling:

6. Prepare the Filling: While the dough is rising, mix together the softened butter, brown sugar, cinnamon, cornstarch (if using), and salt in a small bowl. Set aside.

Assemble the Cinnamon Rolls:

7. Roll Out the Dough: Once the dough has risen, punch it down to release the air. Roll it out on a lightly floured surface into a large rectangle, about 12×18 inches.
8. Spread the Filling: Evenly spread the cinnamon filling over the dough, making sure to cover it all the way to the edges.
9. Roll Up the Dough: Starting from one long edge, roll the dough tightly into a log.
10. Slice the Rolls: Using a sharp knife or dental floss, cut the rolled dough into 12 equal-sized pieces.
11. Place in Pan: Arrange the cinnamon rolls in a greased 9×13-inch baking dish. Let them rest for 30 minutes to an hour to rise again.

Bake the Rolls:

12. Preheat the Oven: Preheat the oven to 350°F (175°C).
13. Bake: Once the rolls have risen, bake them for 25-30 minutes, or until golden brown on top and cooked through.

Make the Glaze:

14. Prepare the Cream Cheese Glaze: While the rolls are baking, beat together the cream cheese, powdered sugar, milk, and vanilla extract until smooth. Adjust the milk as needed to reach your desired glaze consistency.
15. Glaze the Rolls: Once the cinnamon rolls are done baking, let them cool for about 5-10 minutes. Drizzle the cream cheese glaze over the warm rolls, ensuring each one is covered in creamy sweetness.
