Start by peeling and chopping fresh ripe peaches, then combine them in a saucepan with granulated sugar and lemon juice. Cook over medium heat for about 10 minutes, stirring occasionally, until the peaches soften and release their juices. In a separate bowl, mix cornstarch with a bit of water to create a slurry. Pour this into the peach mixture and cook for an additional 2-3 minutes until thickened. Allow the peach jam to cool completely.

In a small pot, whisk together 1/4 cup of water and 1/4 cup of bread flour. Place the pot over medium heat and continuously stir until the mixture thickens to a pudding-like consistency, about 3-5 minutes. Remove from heat and set the tangzhong aside to cool.

In a large mixing bowl, combine 4 cups of bread flour, 1/4 cup of granulated sugar, 2 teaspoons of instant yeast, and 1 teaspoon of fine sea salt. Pour in 1/2 cup of whole milk, 1/4 cup of heavy cream, 1 large egg, 1 teaspoon of vanilla extract, and the cooled tangzhong. Mix until a rough dough forms. Knead the dough on a floured surface for 5-7 minutes until it’s smooth and elastic.

Gradually add 1/2 cup of softened unsalted butter to the dough, kneading for another 5 minutes until fully incorporated. Form the dough into a ball and place it in a lightly greased bowl, covering it with a damp cloth. Allow the dough to rest in a warm place for about 30 minutes, or until it has doubled in size.

Once the dough has risen, turn it out onto a floured surface and roll it into a rectangle about 1/4 inch thick. Spread a mixture of 1/2 cup brown sugar and 2 tablespoons of ground cinnamon evenly over the surface. Spoon your cooled peach jam across the dough, leaving a small border around the edges.

Starting from the long edge, gently roll the dough tightly into a log. Use a sharp knife to cut the log into 12 equal slices. Place each roll, cut side up, in a parchment-lined baking pan, leaving some space between each one. Cover the pan with plastic wrap and let the rolls rise again in a warm spot for 1-2 hours, until they have doubled in size.

Preheat your oven to 325°F (163°C). While the rolls are rising, prepare the crumb topping by mixing together 1/2 cup of all-purpose flour, 1/4 cup of brown sugar, and 1/4 cup of cold, diced butter in a bowl. Sprinkle the topping generously over the risen rolls. Bake the Peach Cobbler Cinnamon Rolls for 30-40 minutes, until they are golden and the tops are firm to the touch.

While the rolls are baking, beat together 4 ounces of softened cream cheese, 2 tablespoons of unsalted butter, 1 cup of powdered sugar, and 2 tablespoons of heavy cream in a mixing bowl until smooth. Once the rolls are out of the oven and still warm, drizzle this glaze generously over them.
