Cinnamon Sugar Sourdough Loaf

A cozy sourdough loaf with a sweet cinnamon sugar swirl, perfect for slow mornings, toast, or a soft treat with coffee.

Ingredients

Dough

  • 500g bread flour
  • 350g water
  • 100g active sourdough starter
  • 10g salt

Cinnamon Sugar Filling

  • 1/3 cup brown sugar
  • 2 tablespoons granulated sugar
  • 1 tablespoon ground cinnamon
  • 2 tablespoons softened butter

Instructions

  1. In a large bowl, mix the flour and water until fully combined. Let rest for 30 minutes.
  2. Add the active sourdough starter and salt, then mix until incorporated.
  3. Perform stretch and folds every 30 minutes for the first 2 hours of bulk fermentation.
  4. Let the dough continue to bulk ferment until it has risen and looks slightly bubbly.
  5. Mix the brown sugar, granulated sugar, and cinnamon in a small bowl.
  6. Turn the dough out onto a lightly floured surface and gently stretch it into a rectangle.
  7. Spread softened butter over the dough, then sprinkle the cinnamon sugar mixture evenly across the surface.
  8. Roll the dough tightly, shape it into a loaf, and place it into a proofing basket or loaf pan.
  9. Cover and refrigerate overnight for the final proof.
  10. Preheat the oven to 450°F. Bake covered for 25 minutes, then uncovered for 15–20 minutes, or until golden brown.
  11. Let the loaf cool completely before slicing.
Tip: Make sure the cinnamon sugar is spread evenly, but avoid overfilling the loaf so the swirl does not leak out while baking.
