Activate the Yeast: Combine the active dry yeast, 1/4 teaspoon sugar, and 2–3 tablespoons warm water in a small bowl. Leave the mixture for 5 minutes, until it becomes frothy. Warm the Milk: Melt the butter together with the milk in a saucepan over low heat until the butter is completely melted. Allow the mixture to cool slightly. Combine the Dough Ingredients: Add the flour and 1/3 cup sugar to a large mixing bowl.Stir in the frothy yeast mixture, slightly cooled milk-and-butter mixture, and eggs until the ingredients come together to form a dough. Knead the Dough: Transfer the dough to a floured surface and knead for about 10 minutes, until it becomes smooth and elastic.
First Rise: Place the dough in a greased bowl and cover it with a damp cloth. Leave it in a warm place for about 1 to 1 1/2 hours, or until it has doubled in size. Prepare the Filling: In a small bowl, combine the 1/3 cup sugar reserved for the filling with the cinnamon and cardamom, mixing until the spices are evenly distributed.
Roll Out the Dough: Once the dough has doubled, gently punch it down. Transfer it to a floured surface and roll it into a rectangle. Add the Filling: Brush the surface of the rolled dough with the egg-and-milk mixture, then spread the cinnamon, cardamom, and sugar mixture evenly over the top.
Shape the Loaf: Starting from one of the longer sides, roll the dough tightly into a log. Pinch the seam closed to help secure the shape.
Second Rise: Place the shaped dough in a greased loaf pan.Cover it and let it rise for about 30–45 minutes, or until it has doubled in size. Preheat the Oven: Preheat the oven to 350°F (175°C).
Brush the Loaf: Once the dough has completed its second rise, brush the top with the egg-and-milk mixture.
Bake the Bread: Bake at 350°F (175°C) for 30–35 minutes, until the loaf is golden brown and sounds hollow when tapped on the bottom.
Cool Before Slicing: Let the bread cool in the pan for 10 minutes, then turn it out onto a wire rack. Allow it to cool completely before slicing.
