Step 1: Prepare the Dough

1. In a large bowl, whisk together flour, cocoa powder, sugar, yeast, and salt.

2. In a separate bowl, combine warm milk, melted butter, egg, vanilla extract, and red food coloring.

3. Gradually mix the wet ingredients into the dry ingredients, stirring until a dough forms.

4. Knead the dough on a floured surface for about 8-10 minutes until smooth and elastic. Alternatively, use a stand mixer with a dough hook.

5. Place the dough in a greased bowl, cover with plastic wrap, and let it rise in a warm place for about 1-2 hours, or until doubled in size.

Step 2: Make the Cinnamon Filling

1. In a small bowl, mix softened butter, brown sugar, cinnamon, and cocoa powder.

2. Stir until you have a smooth, spreadable paste.

Step 3: Roll Out and Fill the Dough

1. Once the dough has doubled in size, roll it out on a floured surface into a rectangle (about 12×18 inches).

2. Spread the cinnamon filling evenly over the dough, covering the entire surface.

Step 4: Roll and Slice the Dough

1. Roll the dough tightly from the long edge to form a log.

2. Use a sharp knife or dental floss to cut the log into 12 equal rolls.

3. Place the rolls in a greased 9×13 inch baking dish, leaving space for them to expand.

4. Cover with a kitchen towel and let them rise again for about 30-45 minutes.

Step 5: Bake the Cinnamon Rolls

1. Preheat the oven to 350°F (175°C).

2. Bake for 18-22 minutes, or until the rolls are golden brown and fully cooked.

3. Let them cool slightly before adding the glaze.

Step 6: Prepare the Cream Cheese Glaze

1. In a bowl, beat cream cheese and butter until smooth.

2. Add powdered sugar and vanilla extract, mixing until combined.

3. Gradually add milk to reach your desired consistency.

Step 7: Glaze and Serve

1. Drizzle or spread the cream cheese glaze over the warm cinnamon rolls.

2. Serve immediately and enjoy!
