Step-by-Step Instructions
1. Prepare the Dough
In a large bowl, mix sourdough starter, warm milk, sugar, and melted butter. Gradually add flour and salt, mixing until a shaggy dough forms. Knead for about 8-10 minutes until smooth and elastic. Cover and let rise at room temperature for 6-8 hours (or overnight in the fridge for deeper flavor).




2. Roll and Fill
On a floured surface, roll the dough into a rectangle (about 12×18 inches). Spread the softened butter over the dough, then sprinkle with brown sugar and cinnamon. Roll tightly from the short side to create a log.







3. Shape and Second Rise
Slice the log in half lengthwise to expose the swirls. Twist the two halves together and place them in a greased loaf pan. Cover and let rise for another 1-2 hours until puffy.




4. Bake to Perfection
Preheat oven to 375°F (190°C). Bake for 35-40 minutes until golden brown and fragrant. Allow to cool slightly before glazing.

5. Add the Glaze (Optional)
Mix powdered sugar, milk, and vanilla extract until smooth. Drizzle over the loaf while still slightly warm.

Serving & Storing
This loaf is best enjoyed fresh but can be stored in an airtight container for up to 3 days. Toast slices and add butter for an extra indulgent treat!
