1First, make the Tangzhong paste by combining 1/3 cup milk, 1/2 cup hot tap water, and 1/3 cup bread flour in a pot. Cook until it forms a paste.
2In a large mixing bowl, combine the prepared Tangzhong paste, 2/3 cup warm whole milk, 1/2 cup sugar, 3 tablespoons melted butter, 1 egg, and 3 teaspoons instant yeast.
3Whisk the wet ingredients until well combined.
4Add 1 teaspoon salt and 3 2/3 cups bread flour to the wet mixture.
5Mix the ingredients using a stand mixer until a dough forms.
6Knead the dough until it's smooth and elastic, then place it in a greased bowl to proof.
7Roll out the dough into a large rectangular shape using a rolling pin.
8Spread 8 tablespoons of softened butter evenly over the rolled-out dough.
9Sprinkle 1 cup of packed light brown sugar and 2 tablespoons of cinnamon over the butter.
10Tightly roll the dough from one end to the other.
11Cut the rolled dough into individual cinnamon rolls.
12Place the cut cinnamon rolls on a sheet tray lined with parchment paper.
13Pour 1/2 cup of heavy whipping cream over the rolls before baking.
14Bake the rolls at 375 degrees Fahrenheit (190 degrees Celsius) for 18-20 minutes.
15Once baked and slightly cooled, slather the rolls with cream cheese frosting.
