In a large bowl, combine melted butter, warm milk, sugar, and yeast. Let it sit for 5 minutes.
Gradually add 600g flour, baking powder, salt, cocoa, and red food paste. Mix until the dough comes together.
Add the remaining 100g flour as needed to form a soft dough.
Knead the dough for 5-7 minutes, cover, and let it rise for about 1 hour until doubled in size.
Roll out the dough into a rectangle.
Brush with melted butter and sprinkle with white sugar, brown sugar, and cinnamon.
Roll the dough tightly into a log and cut into 12 rolls. Place them in a greased baking dish and let them rise for another 30 minutes.
Bake at 170°C for 25-30 minutes.
For the topping, whisk together cream cheese, melted butter,vanilla, milk, and powdered sugar. Spread over the rolls once they’ve cooled slightly.
