The sourdough provides depth and moisture, while the careful balance of sugar, fat, and leavening creates a cake that holds its shape and slices cleanly without needing any glaze.
Prepare the Bundt Pan
Grease a 10–12 cup Bundt pan thoroughly with butter or non-stick spray, making sure to get into every groove.
Lightly dust with flour, tapping out the excess.
Proper pan preparation ensures a clean release and a perfect Bundt shape.
Mix Dry Ingredients
In a medium bowl, whisk together flour, baking powder, baking soda, salt, and cinnamon if using. Set aside.
This ensures even distribution of leavening agents and spices.
Cream Butter and Sugars
In a large bowl, beat softened butter with granulated sugar and brown sugar until light and fluffy, about 3–4 minutes.
Add eggs one at a time, beating well after each addition.
Stir in vanilla extract and citrus zest if desired.
Creaming the butter and sugar thoroughly creates a light, airy texture in the final cake.
Incorporate the Sourdough Starter
Mix in the active sourdough starter until fully combined.
The starter adds subtle tang and keeps the cake moist and tender.
Alternate Adding Dry Ingredients and Milk
With the mixer on low speed, add one-third of the dry ingredients to the butter mixture. Mix until just combined.
Add half of the milk, mixing gently. Repeat, ending with the remaining dry ingredients.
Avoid overmixing to prevent a dense cake. Alternating milk and dry ingredients ensures a tender, even crumb.
Pour Batter into Bundt Pan
Transfer the batter into the prepared Bundt pan, smoothing the top with a spatula.
Tap the pan gently on the counter to remove air bubbles, which ensures an even bake.
Bake the Cake
Preheat the oven to 350°F (175°C). Bake for 50–60 minutes, or until a toothpick inserted into the center comes out clean.
Check around 45 minutes; if the top is browning too quickly, cover loosely with foil.
Cool and Release from Pan
Let the cake cool in the pan for 10–15 minutes.
Invert onto a wire rack and gently tap to release.
Allow the cake to cool completely before slicing to maintain structure and texture.
Flavor and Texture Highlights
- Tender, moist crumb from sourdough starter
- Subtle tang that balances sweetness
- Buttery richness for comfort and indulgence
- Warm spice or bright citrus adds extra depth

- Ensure your sourdough starter is active for best rise.
