01 - Combine warm milk, warm water, sugar, and yeast in a large bowl. Let stand for 5–10 minutes until mixture becomes frothy and activated.
02 - Whisk melted butter, eggs, and salt into the yeast mixture. Gradually incorporate flour until a soft, tacky dough forms that pulls away from the bowl sides.
03 - Turn dough onto a lightly floured surface and knead for 8–10 minutes until smooth and elastic. Transfer to a greased bowl, cover with plastic wrap, and let rise in a warm area for 1–1.5 hours until doubled in volume.
04 - Melt butter in a saucepan over medium heat. Add peaches, brown sugar, cornstarch, cinnamon, and nutmeg. Cook while stirring constantly for 5–7 minutes until peaches soften and mixture thickens. Cool completely before using.
05 - Combine brown sugar and cinnamon in a small bowl, mixing until evenly blended.
06 - Punch down risen dough and roll out on a floured surface into a 16x12-inch rectangle. Spread softened butter evenly over surface, sprinkle with cinnamon sugar mixture, then distribute cooled peach filling.
07 - Roll dough tightly from the long edge into a log. Slice into 12 equal pieces and arrange cut-side up in a greased 9x13-inch baking dish.
08 - Cover baking dish with a clean towel and let rolls rise for 30–45 minutes until puffy and nearly doubled in size.
09 - Bake at 350°F for 25–30 minutes until golden brown on top and cooked through. The internal temperature should reach 190°F when fully baked.
10 - Whisk powdered sugar, milk, vanilla extract, and salt in a small bowl until completely smooth and free of lumps. Adjust consistency with additional milk if needed.
11 - Drizzle warm glaze evenly over slightly cooled rolls. Serve warm for best texture and flavor.
