In a large bowl, whisk together the flour, granulated sugar, instant yeast, and a pinch of salt.

Warm the milk and melted butter until just lukewarm. Gently pour it into the dry ingredients, mixing until well incorporated.

Beat in the eggs until the mixture is smooth and blended.

On a lightly floured surface, knead the dough for about 8-10 minutes until it becomes smooth and elastic.

Place the kneaded dough in a greased bowl, cover it, and let it rise in a warm spot until doubled in size, about 1 hour.

Transfer the dough to a floured surface and roll it into a rectangle. Spread softened butter over the surface.

Evenly sprinkle the brown sugar, ground cinnamon, and nutmeg over the buttered dough.

Carefully roll the dough tightly from one side to the other, forming a log. Slice into equal pieces.

Place the rolls in a greased baking dish. Cover loosely and let them rise for another 30 minutes.

Preheat your oven to 350°F (175°C). Bake for about 25 minutes or until golden brown.

Whisk together the powdered sugar, milk, and vanilla extract in a small bowl, then drizzle over the warm rolls.
