In a large mixing bowl, combine 4 cups of all-purpose flour, 2 teaspoons of instant yeast, 2 tablespoons of sugar, and 1 teaspoon of salt. Gradually stir in 1.5 cups of warm water and 4 tablespoons of melted unsalted butter until a cohesive dough forms.

Transfer the dough onto a floured work surface. Knead the dough for about 5-7 minutes until it becomes smooth and elastic.

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

While the dough rises, mix the filling by combining 4 tablespoons of softened unsalted butter, 4 cloves of minced garlic, 2 tablespoons of chopped fresh herbs, and any optional add-ins.

Once risen, roll the dough into a rectangle and spread the filling evenly over the surface. Roll tightly and slice into 12 equal pieces.

Arrange the sliced rolls in a greased baking dish, cover loosely and let rise for another 30-40 minutes.

Preheat your oven to 375°F (190°C) and bake the rolls for 20-25 minutes until golden brown.

Once baked, let cool in the pan for about 5 minutes before transferring to a cooling rack or serving platter.
