Ingredients
For the Bread:
-
1 cup active sourdough starter (fed and bubbly)
-
1/2 cup milk (dairy or plant-based), room temperature
-
2 large eggs, room temperature
-
1/2 cup granulated sugar
-
1/3 cup neutral oil (canola or vegetable)
-
2 teaspoons vanilla extract
-
2 cups all-purpose flour
-
1 teaspoon baking powder
-
1/2 teaspoon baking soda
-
1/2 teaspoon salt
-
1 tablespoon ground cinnamon
For the Topping:
-
1/4 cup melted butter
-
1/3 cup granulated sugar
-
1 teaspoon ground cinnamon
Instructions
-
Preheat oven to 350°F (175°C). Grease and flour a standard loaf pan or line with parchment paper.
-
In a large bowl, whisk together the sourdough starter, milk, eggs, sugar, oil, and vanilla until smooth.
-
In another bowl, mix the flour, baking powder, baking soda, salt, and cinnamon. Stir into the wet mixture until just combined—do not overmix.
-
Pour the batter into the prepared loaf pan. Bake for 45–50 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.
-
While warm, brush with melted butter. Mix sugar and cinnamon, then sprinkle over the loaf, pressing lightly to help it stick.
-
Cool completely before slicing to maintain the soft, donut-like texture.
Notes
-
This bread works beautifully with sourdough discard too—just note the flavor will be a bit milder.
-
Want a swirl? Mix an extra tablespoon of cinnamon with brown sugar and layer it in the middle.
-
Freezes like a dream! Slice before freezing for easy grab-and-toast mornings.
