Combine warm milk, yeast, and granulated sugar in a small bowl and let it sit for about 5-10 minutes until bubbly.

In a large bowl, combine all-purpose flour, salt, butter, eggs, and vanilla extract. Gradually mix in the yeast mixture and knead on a floured surface for 5-7 minutes until smooth.

Transfer the dough to a greased bowl, cover it, and let it rise in a warm area for about 1 hour or until doubled in size.

While the dough is rising, mix granulated sugar and ground cinnamon together. Set aside.

Punch down the risen dough, roll it out into a rectangle, spread butter, and sprinkle the cinnamon-sugar mixture. Cut into strips and twist into a snowflake shape.

Let the shaped snowflake rise for another 30 minutes on a baking sheet.

Preheat the oven to 350°F (175°C). Bake the snowflake for 20-25 minutes or until golden brown on top.

Let it cool for 10-15 minutes on a wire rack.

Mix powdered sugar with milk until creamy, and drizzle over the slightly cooled bread.
