Combine warm milk, 1/2 cup melted butter, yeast, and 1/2 cup granulated sugar in a large bowl. Let it sit for 5 minutes until foamy—you'll see it get bubbly, which means the yeast is waking up. Add eggs and stir until combined. This mixture should feel warm but not hot to the touch (around 110°F).
In a separate bowl, whisk together 4 cups flour, 1 teaspoon salt, and set aside. Pour the wet mixture into the dry ingredients and mix until a shaggy dough forms. Knead for 8-10 minutes by hand (or use a stand mixer for 6 minutes) until the dough becomes smooth and slightly elastic. Don't panic if it's a little sticky at first—that's totally normal.
Place dough in a greased bowl, cover with plastic wrap, and let it rise in a warm spot for about 1 hour until doubled in size. I like to turn my oven light on and close the oven door for the perfect warm environment. You'll know it's ready when you poke it and the indent slowly springs back.
Roll out the dough on a floured surface into a 16x12 inch rectangle. Mix 1/4 cup brown sugar and 1 tablespoon cinnamon together in a small bowl, then spread this mixture evenly over the dough. Starting from the long side, roll it up tightly and cut into 12 equal pieces using a sharp knife (or dental floss, which sounds weird but honestly works better).
Place rolls in a greased 9x13 inch baking pan, cover loosely with plastic wrap, and let them rise for 30-45 minutes until puffy. They should nestle close together but still have a little space between them. Meanwhile, preheat your oven to 350°F about 10 minutes before you're ready to bake.
Bake for 20-25 minutes until the tops are golden brown and you can smell that incredible cinnamon aroma filling your kitchen. They'll look slightly underbaked but trust me—they keep cooking after you pull them out. Don't overbake or they get dry on the edges.
While rolls cool for 5 minutes, beat cream cheese, 1/4 cup powdered sugar, and 1 tablespoon honey together until smooth and spreadable. Frost the warm rolls generously, and watch as it melts right into all those beautiful cinnamon swirls. This is the moment I live for every single time.
