In a large mixing bowl, combine the all-purpose flour, granulated sugar, and salt.
In a small bowl, dissolve the active dry yeast in the warm milk. Let it sit for 5 minutes until frothy.
Pour the melted butter and beaten eggs into the mixing bowl with the dry ingredients.
Slowly add the yeast mixture and stir until a dough forms. If the dough feels too sticky, add additional flour, 1 tablespoon at a time.
Knead the dough on a floured surface for about 5-7 minutes until it becomes smooth and elastic.
Place the dough in a greased bowl, cover with a clean kitchen towel, and let it rise in a warm spot for about 1 hour, or until it has doubled in size.
While the dough is rising, prepare the cinnamon filling by combining the ground cinnamon, brown sugar, and softened butter in a small bowl. Mix well until a smooth paste forms.
Once the dough has risen, punch it down to release any air bubbles. Roll it out on a floured surface into a large rectangle, about ¼ inch thick.
Spread the cinnamon filling evenly over the rolled-out dough, leaving a small border around the edges.
Starting with the longer side, tightly roll the dough into a log, gently pinching the seam to seal it.
Cut the log into 12 equal-sized rolls. Place them in a greased baking dish, leaving a little space between each roll to allow for rising.
Cover the baking dish with a clean kitchen towel and let the rolls rise for another 30-45 minutes, or until they have doubled in size.
Preheat the oven to 350°F (175°C). Bake the cinnamon rolls for 20-25 minutes, or until they are golden brown and cooked through.
While the cinnamon rolls are baking, prepare the glaze by whisking together the powdered sugar, vanilla extract, and milk in a small bowl. Adjust the consistency by adding more milk for a thinner glaze or more powdered sugar for a thicker glaze.
Remove the cinnamon rolls from the oven and let them cool for a few minutes.
Drizzle the glaze over the warm cinnamon rolls, allowing it to seep into the crevices.
Serve the cinnamon rolls warm and enjoy the gooey, cinnamon-infused deliciousness!
