Make the dough:

• In a large bowl, dissolve yeast in warm milk and let sit for 5-10 minutes until foamy.
• Add sugar, melted butter, eggs, flour, and salt. Mix until a dough forms.
• Knead the dough for 5-7 minutes until smooth and elastic (or use a stand mixer with a dough hook). Cover the bowl with a towel and let the dough rise for 1 hour, or until doubled in size.

Prepare the peach filling:

• In a saucepan over medium heat, combine diced peaches, brown sugar, cinnamon, nutmeg, and cornstarch (if using fresh peaches).
• Cook for 5-7 minutes until the mixture thickens, then set aside to cool.

Prepare the cinnamon sugar filling:

• In a small bowl, mix the softened butter, brown sugar, and cinnamon until smooth.

Roll out and fill:

• Punch down the dough and roll it out on a floured surface into a rectangle (about 12×18 inches).
• Spread the cinnamon sugar mixture evenly over the dough.
• Spoon the cooled peach filling on top, distributing evenly.

Shape the rolls:

• Roll up the dough tightly from the long side and slice into 12 equal rolls.
• Place the rolls in a greased 9×13-inch baking dish. Cover and let rise for another 30 minutes.

Prepare the cobbler topping:

• In a small bowl, mix together the flour, brown sugar, butter, and cinnamon until crumbly.
• Sprinkle the topping over the risen cinnamon rolls.

Bake:

• Preheat the oven to 350°F (175°C).
• Bake the rolls for 25-30 minutes, or until golden brown and cooked through.

Make the glaze:

• In a bowl, whisk together powdered sugar, milk, and vanilla until smooth. Drizzle over the warm cinnamon rolls.

Serve:

• Serve warm, and enjoy the gooey, peachy, cinnamon goodness!
