Equipment

Ingredients

Dry Ingredients

  • 2 cups flour
  • 1/2 teaspoon salt
  • 1 teaspoon cinnamon
  • 1 teaspoon baking powder
  • 1/2 teaspoon baking soda

Wet Ingredients

  • 8 tablespoons butter melted
  • 1 cup sugar
  • 1 teaspoon vanilla
  • 2 large eggs
  • 3/4 cup sourdough discard

Cinnamon Swirl

  • 1 tablespoon cinnamon
  • 1/2 cup brown sugar

Glaze (optional)

  • 1/2 cup powdered sugar
  • 1 tablespoon water
  • 1/8 tsp vanilla

Instructions

  • Preheat your oven to 350 degrees.
  • Melt the butter, then let it cool until warm, but not hot.
  • Prepare your loaf pan by brushing with butter or coconut oil, or line with parchment paper.
  • In a large mixing bowl, whisk the melted butter, sugar, vanilla, eggs, and starter.
  • In a separate bowl, combine the dry ingredients: flour, salt, cinnamon, baking powder, and baking soda.
  • Gradually add the bowl of dry ingredients into the wet ingredients, then mix until it's just combined.
  • In a small bowl create the cinnamon swirl by mixing the cinnamon and brown sugar, then set to the side.
  • Add half of the dough into the loaf pan, then sprinkle 3/4 of the cinnamon sugar mixture over the top.
  • Add the remaining batter, followed by the rest of the cinnamon sugar.
  • Using a knife, make swirls through the batter to spread the cinnamon sugar throughout, then smooth over the top.
  • Bake at 350 for 60-70 minutes until golden brown. Check if it's baked through by pricking it with a sharp knife or toothpick. If it comes out clean, the loaf is done.
  • Cool for 20 minutes or so.
  • For the optional glaze, whisk together the powdered sugar, water, and vanilla until smooth.
  • Drizzle over the loaf and enjoy!

Notes

  • If using the optional glaze, try adding it when the bread is still a touch warm. It soaks into the bread and is so tasty!
  • Plan ahead for a longer fermentation if you want a tangier flavor to your bread. That is the best version, in my opinion. Directions in the post.
  • Mix until just combined, being careful not to overmix. We want to keep it tender and light!
  • If your loaf has not finished baking but is browning too much on top, cover it with a sheet of aluminum foil or parchment paper for the remainder.
  • My kids actually preferred splitting the cinnamon sugar 50/50 rather than a 75/25. Either works. 75/25 gives that true swirl.
