Prepare Yeast Mixture: In a small bowl, combine 1 cup of warm milk (about 110°F) with 2 teaspoons of active dry yeast. Allow this mixture to sit for 10 minutes until it becomes frothy and bubbly.

Mix Dry Ingredients: In a large mixing bowl, whisk together 4 cups of all-purpose flour, ½ cup of granulated sugar, 1 teaspoon of salt, and 2 teaspoons of cinnamon.

Combine Ingredients: Pour the frothy yeast mixture into the dry ingredients, followed by ¼ cup of melted unsalted butter and 2 large eggs. Stir until a shaggy dough begins to form.

Knead Dough: Transfer the dough to a floured surface and knead it for about 10 minutes until it becomes smooth and elastic.

First Rise: Grease a large bowl with a bit of melted butter, place the kneaded dough inside, cover and let it rise in a warm area for about 1 hour, or until it has doubled in size.

Roll Out Dough: Roll it out onto a floured surface into a rectangle approximately 16x12 inches in size, then spread ¼ cup of softened butter over the surface and sprinkle with ½ cup of brown sugar and 2 tablespoons of cinnamon.

Cut and Second Rise: Carefully roll the dough up tightly, cut into 12 equal pieces and place in a greased baking pan. Cover and let rise for 30 minutes.

Bake: Preheat oven to 350°F (175°C) and bake for 25 minutes or until golden brown on top.

Prepare Icing: Mix 1 cup of powdered sugar with 2-4 tablespoons of milk until smooth.

Drizzle Icing: Once the rolls have cooled slightly, drizzle the icing generously over the top.
