Instructions

• In the bowl of a stand mixer whisk 120 milliliters of the milk, 1 tablespoon of the sugar, and the yeast and let stand until frothy, about 5 minutes. Using the paddle attachment with the mixer on low speed, add the remaining 180 milliliters milk, the remaining 50 grams sugar, the salt, and eggs and beat for 1 minute. Change to the dough hook and gradually add 770 grams of the flour. Starting on low speed and working slowly up to medium, mix until the dough is fairly smooth, about 3 minutes. Reduce the speed to medium-low and add 225 grams butter and the remaining 70 grams flour. Transfer the dough to a floured work surface and knead until the dough is soft, smooth, and tacky (but not sticking to the work surface), about 2 minutes. Transfer the dough to an oiled bowl, cover, and let rise in a warm place until doubled in bulk, about 1½ hours.
• Combine the brown sugar and cinnamon. Press the dough down, and then turn out onto a lightly floured surface. Knead the dough two to three times, and then roll out into a rectangle 61 centimeters long by 30.5 centimeters wide. Spread the dough all over (do not leave a border) with 90 grams of the butter. Sprinkle evenly with the cinnamon sugar. Starting at the long side closest to you, tightly roll up the dough, and then pinch the seam closed. Cut the log of dough into twelve 5-centimeter pieces. Generously grease the bottom and sides of a 25-centimeter cast-iron skillet or metal cake pan with the remaining butter and arrange the rolls, cut side up, in a single layer. Cover with aluminum foil and let stand at room temperature for 1 hour, or refrigerate overnight. (If refrigerating, return to room temperature before proceeding, about 2 hours.)
• Prepare the grill for indirect cooking over medium heat (as close to 190ºC as possible).
• Place the skillet with the rolls covered with foil over indirect medium heat, close the lid, and cook for 25 minutes. Wearing insulated barbecue gloves, rotate the skillet 180 degrees, close the lid, and cook for 10 minutes. Remove the foil from the skillet and continue cooking until the dough is cooked through and the tops are lightly browned, 20 to 30 minutes more. Remove from the grill, set on a heatproof surface, and let cool for 10 minutes. Meanwhile, make the icing.

• In a large bowl mash the cream cheese with the milk. Sift the confectioners' sugar into the bowl, and then stir to combine. Add the vanilla and salt and whisk until smooth. Spread the icing over the top of the warm rolls and let stand for 10 minutes. Using a thin-edged knife, cut between the seams of the rolls and transfer to a platter or cooling rack. Serve warm or at room temperature.
