Let's kick things off. In a small bowl, combine the warm milk and yeast, allowing it to sit until it becomes frothy—about 5 to 10 minutes. This simple act brings yeast to life, making it essential for a fluffy bun.

In a large bowl, mix flour, cardamom, brown sugar, and salt. Create a well in the center. Add the yeast-milk mixture and softened butter. Mix until a rough dough forms.

Time to get physical! Lightly flour a clean surface and turn your dough out. Knead for about 8 to 10 minutes until smooth. You want a dough that springs back when pressed—a classic sign that you’ve done well. It should be pliable, soft, and just slightly sticky.

Place the dough in a greased bowl, cover it with a kitchen towel or plastic wrap, and let it rise in a warm place. Aim for about 1 hour, or until it has doubled in size. This is where the magic happens.

While your dough is rising, let’s prepare the filling! In a small bowl, mix softened butter, brown sugar, cardamom, and optional cinnamon. Put it aside for now, relishing the sweet, spicy aroma.

After the dough has doubled, punch it down gently to release air. Transfer it to a floured surface and roll it out into a rectangle about ½-inch thick.

Spread the filling evenly over the surface. Roll the dough tightly from the long side, creating a log. Cut it into 10 to 12 equal pieces. Place those rolls, cut side up, in a greased baking dish, allowing them to touch slightly.

Cover your rolls again and let them rise for another 30-40 minutes. Patience is key here!

Preheat your oven to 375°F (190°C). In the meantime, beat the egg in a small bowl. Brush the tops of the buns gently with the egg wash for that golden sheen. Sprinkle with cane or pearl sugar—absolutely tempting!

Pop those buns into the preheated oven and bake for 15-20 minutes or until golden brown. The smell will be simply divine! You might find it hard to resist opening the oven just to get a whiff.

Once they are out of the oven, allow them to cool slightly before indulging. Each bun will be warm, fluffy, and irresistible. They are best enjoyed fresh but can also be stored for later!
