Ingredients for Sourdough Carrot Cake
The beauty of this recipe lies in its simplicity. You likely already have most of the ingredients in your kitchen.
You’ll need:
- 1 cup sourdough starter (discard or fed starter, both work)
- 1 cup vegetable oil
- 2 cups all-purpose flour
- 1 1/2 cups granulated sugar
- 1 teaspoon baking powder
- 1/2 teaspoon baking soda
- 1 teaspoon cinnamon
- 1/2 teaspoon nutmeg
- 1/4 teaspoon salt
- 3 large eggs
- 2 cups grated carrots
- 1/2 cup chopped walnuts (optional)

For the Cream Cheese Frosting:
- 8 oz cream cheese, softened
- 1/4 cup unsalted butter, softened
- 2 cups powdered sugar
- 1 teaspoon vanilla extract
Step by Step Sourdough Carrot Cake Recipe
Step 1: Preheat the Oven
Preheat your oven to 350°F (175°C). Grease and flour an 8-inch round or square cake pan.
Step 2: Prepare the Dry Ingredients
In a medium bowl, whisk together the flour, baking powder, baking soda, cinnamon, nutmeg, and salt. Set aside.
Step 3: Mix the Wet Ingredients
In a large mixing bowl, beat together the sourdough starter, oil, and sugar until combined. Add the eggs, one at a time, beating well after each addition. Mix in the vanilla extract.
Step 4: Add the Carrots and Dry Ingredients
Gradually stir the dry ingredients into the wet mixture, mixing until just combined. Fold in the grated carrots and optional chopped walnuts.
Step 5: Bake the Cake
Pour the batter into your prepared cake pan and smooth the top. Bake for 30-35 minutes, or until a toothpick inserted into the center comes out clean.
Step 6: Cool the Cake
Allow the cake to cool in the pan for 10 minutes before transferring it to a wire rack to cool completely.
Step 7: Make the Cream Cheese Frosting
While the cake cools, make the frosting by beating together the cream cheese and butter until smooth. Gradually add the powdered sugar and vanilla extract, and continue to beat until fluffy.
Step 8: Frost the Cake
Once the cake has cooled, spread the cream cheese frosting over the top and sides. You can also decorate with extra chopped walnuts if desired.
Pro Tips for Perfect Sourdough Carrot Cake
- Use freshly grated carrots for the best texture and flavor.
- Don’t overmix the batter to avoid a dense cake. Stir just until the ingredients are combined.
