Everything You Need for Baked Sourdough Cake Donuts

- 1/4 cup unsalted butter, melted
- 1 large egg
- 1 teaspoon vanilla extract
- 1/2 teaspoon baking soda
- 1 teaspoon baking powder
- 1/2 teaspoon salt
- 1 teaspoon ground cinnamon
- 1 1/2 cups all-purpose flour
- 1/4 cup milk
The sourdough discard gives these donuts their signature tang while helping to keep them moist. Ground cinnamon adds a cozy warmth that pairs wonderfully with the sweetness of the batter.
How to Make Baked Sourdough Cake Donuts Step by Step
- Preheat your oven to 350°F (175°C) and grease a donut pan to ensure the donuts release easily after baking.
- In a large mixing bowl, combine the sourdough discard, granulated sugar, and melted butter. Mix until well incorporated.
- Add the egg and vanilla extract to the mixture, stirring until smooth and evenly combined.
- In a separate bowl, whisk together the baking soda, baking powder, salt, cinnamon, and all-purpose flour to ensure even distribution of dry ingredients.
- Gradually add the dry ingredients to the wet mixture, alternating with the milk. Mix until the batter is just combined — avoid overmixing.
- Transfer the batter to a piping bag or a zip-top bag with the corner snipped, and pipe it into the prepared donut pan, filling each mold about halfway.
- Bake in the preheated oven for 12-15 minutes, or until a toothpick inserted into the center of a donut comes out clean.
- Let the donuts cool in the pan for about 5 minutes before transferring them to a wire rack to cool completely.

If you want to freeze them, wrap each donut individually in plastic wrap, then place them in a freezer-safe bag. Reheat them in a 300°F (150°C) oven or microwave for a few seconds to restore their soft texture.
