Method
 

Instructions
  1. Make the Levain: Combine starter, flour, and water. Cover and let rise 4-6 hours.
  2. Make the Dough: Combine flours and sugar. In a separate bowl, whisk butter, egg, and milk. Add levain to dry ingredients, then gradually add wet ingredients, mixing until a shaggy dough forms.
  3. Knead the Dough: Knead for 8-10 minutes (or 6-8 minutes with a stand mixer) until smooth and elastic.
  4. First Rise: Place dough in an oiled bowl, cover, and let rise in a warm place for 2-3 hours, or until doubled.
  5. Prepare Filling: Combine melted butter, brown sugar, and cinnamon.
  6. Assemble Buns: Roll dough into a rectangle (12x18 inches), spread filling, roll up tightly, and slice into 12 buns.
  7. Second Rise: Place buns in a greased 9x13 inch pan, cover, and let rise for 1-1.5 hours, or until almost doubled.
  8. Bake: Preheat oven to 375°F (190°C). Bake for 25-30 minutes, or until golden brown.
  9. Make Glaze: Whisk together powdered sugar, milk, and vanilla extract. Add more milk if needed.
  10. Glaze and Cool: Let buns cool slightly before drizzling with glaze. Serve warm.

Notes

For a richer flavor, use a combination of brown and white sugar in the filling. You can also add raisins, pecans, or walnuts to the filling for added texture and flavor. Ensure your starter is active before beginning.
