Equipment

  • Large mixing bowl
  • Whisk
  • Wooden spoon or spatula
  • 9×5-inch loaf pan
  • Parchment paper
  • Small bowl
  • Knife or skewer (for swirling)
  • Wire rack

Ingredients
  

Dough:

  • 2 cups 250g all-purpose flour
  • 1 teaspoon baking soda
  • 1/2 teaspoon kosher salt
  • 1 teaspoon cinnamon
  • 3/4 cup 150g granulated sugar
  • 1/2 cup 120g sourdough discard
  • 1/2 cup 120ml whole milk
  • 1/4 cup 60ml melted butter
  • 1 large egg
  • 1 teaspoon vanilla extract

Cinnamon Swirl:

  • 1/2 cup 100g brown sugar
  • 2 teaspoons cinnamon

Vanilla Icing:

  • 1/2 cup 60g powdered sugar
  • 1 tablespoon milk
  • 1/2 teaspoon vanilla extract

Instructions
 

  • Line a 9x5-inch loaf pan with parchment paper and lightly grease it.
  • In a large mixing bowl, whisk together the flour, baking soda, salt, cinnamon, and granulated sugar.
  • Add the sourdough discard, milk, melted butter, egg, and vanilla extract to the bowl. Stir with a wooden spoon or spatula until just combined. Do not overmix.
  • In a small bowl, mix the brown sugar and cinnamon together.
  • Pour 1/3 of the batter into the prepared loaf pan. Sprinkle 1/3 of the cinnamon sugar mixture over the batter. Repeat two more times, ending with batter on top.
  • Cover the pan and let the batter rest at room temperature for up to 2 hours to enhance flavor. (Optional)
  • Preheat the oven to 350°Fahrenheit (175°Celsius). Bake for 40–45 minutes, or until a toothpick inserted in the center comes out clean.
  • Let the bread cool in the pan for 10 minutes, then transfer to a wire rack to cool completely before adding icing.
  • In a small bowl, whisk together the powdered sugar, milk, vanilla extract, and a pinch of salt until smooth. If the icing is too thick, add more milk, 1 teaspoon at a time, until it reaches a drizzling consistency.
  • Drizzle the icing over the cooled bread using a spoon or piping bag. Let it set for a few minutes before slicing.

Notes

Layering is Everything – Don’t just dump all the cinnamon sugar mixture in one spot—layering it evenly gives you the perfect swirl in every bite.
Don’t Overmix – Stir until the wet and dry ingredients are just combined. Overmixing can lead to a dense loaf instead of a soft, tender crumb.
Check for Doneness – Since this bread has a thick batter, make sure to test with a sharp knife or toothpick in the middle of the loaf to ensure it’s baked through.
Let It Cool Before Slicing – The cinnamon sugar mixture needs time to set so it doesn’t sink into the bread when you cut into it.
