In a large bowl, combine warm milk, sugar, melted butter, and active dry yeast. Stir well and let it sit for 10 minutes until the yeast has bloomed. Ensure the mixture is just warm, registering between 37-43˚C. If warmer, allow to cool slightly.
Add 520 grams of flour to the milk mixture and stir with a wooden spoon until just combined.
Cover the bowl with a kitchen towel or plastic wrap and let rise in a warm place for 1 hour, until nearly doubled in size.
Generously butter two 20 cm round baking pans and set aside.
In a medium bowl, combine brown sugar, butter, cinnamon, cacao, and vanilla extract. Mix well and set aside.
Remove the plastic wrap from the dough and add the remaining flour, baking powder, and salt. Stir well, then turn out onto a clean surface. Leave a bit of flour nearby to use as needed, but try not to incorporate too much.
Knead the dough for at least 10 minutes, adding more flour as necessary, until the dough just loses its stickiness and does not stick to the surface or your hands. The dough should be very smooth and spring back when poked.
Roll the dough out into a large rectangle, about 1 cm thick. Use a bench scraper or spatula to fix the corners, ensuring they are sharp and even.
Spread the filling evenly over the dough.
Sprinkle the chocolate drops over the rolled-out dough.
Starting from one short end, roll up the dough into a log and pinch the seam closed.
Place seam-side down and trim any uneven ends. Using a sharp knife, cut the log into evenly sized pieces, about 8 cm thick. Place the cinnamon rolls in the prepared pans, one in the center and about 5 around the sides.
Cover with a towel and let rise in a warm place for 35-45 minutes, until expanded by about half of their original volume. (If saving for later, cover with plastic wrap and freeze for up to 3 months).
Preheat the oven to 180˚C.
In a pan, melt sugar combined with water until golden brown. Do not overmix. Add the butter and cream, stirring quickly until the mixture becomes runny again.
Bake the cinnamon rolls for 25-30 minutes, until golden brown.
Once finished, let the cinnamon rolls cool for about 10 minutes.
Drizzle the caramel over the cinnamon rolls, using the back of a spoon to spread if desired. Enjoy your delicious homemade cinnamon rolls!
