Sourdough Blueberry Buckle Ingredients
• Get ready to create a deliciously tender cake!
For the Batter
- All-purpose flour – Provides structure for the cake; substitute with gluten-free flour for a gluten-free option.
- Baking powder – Acts as a leavening agent, ensuring a fluffy rise.
- Salt – Enhances flavor; try using unrefined salt for added minerals.
- Butter – Adds richness; must be softened for the best texture.
- Granulated sugar – Sweetens the cake; coconut sugar is a lower glycemic alternative.
- Sourdough Starter – Infuses the batter with tangy flavor; use discard that’s 24-48 hours old for optimal results.
- Milk – Keeps the batter moist; feel free to swap in any non-dairy milk for a vegan version.
- Egg – Binds the ingredients together; replace with a flax egg for a vegan option.
- Vanilla Extract – Provides warmth and sweetness; opt for pure vanilla for the best flavor.
- Lemon zest – Brightens the overall taste; orange zest is a fine substitute if you prefer.
For the Topping
- Blueberries – The star of this dish; fresh blueberries are best, but you can use frozen ones without thawing.
- Brown sugar – Adds a hint of caramel flavor to the topping; finely packed for best results.
- Ground cinnamon – Enhances the sweetness and warmth of the topping; perfect for a cozy touch.
- Flour – Used to bind the streusel; make sure to use it fresh for the best crumbly consistency.
- Cold, cubed butter – Ensures a crunchy streusel topping; do not use melted butter to maintain texture.
Step‑by‑Step Instructions for Sourdough Blueberry Buckle
Step 1: Preheat and Prepare
Begin by preheating your oven to 375°F (190°C). While the oven heats, grease a round or 9×9 square baking pan or line it with parchment paper to prevent sticking. This crucial first step sets the stage for a beautifully baked Sourdough Blueberry Buckle, ensuring it rises evenly and achieves a golden crust.
Step 2: Make the Crumble Topping
In a medium bowl, combine the crumble topping ingredients: white sugar, brown sugar, flour, ground cinnamon, and cold, cubed butter. Use a pastry cutter or your fingers to mix until the mixture resembles coarse crumbs. Chill this blend in the refrigerator until you’re ready to sprinkle it over the buckle—this maintains that lovely, crunchy texture!
Step 3: Combine Dry Ingredients
In a separate bowl, whisk together the all-purpose flour, baking powder, and salt. This step is essential for evenly distributing the leavening agent and seasoning within the dry ingredients. Set this bowl aside as you move on to prepare your wet ingredients for the Sourdough Blueberry Buckle, which will provide the perfect balance of flavors.
Step 4: Cream the Butter and Sugar
In a stand mixer, cream the softened butter and granulated sugar together on medium speed until the mixture is fluffy and pale—this typically takes about 3-5 minutes. Adding air during this step is vital, as it contributes to the light texture of your cake. Once creamy, add in the egg and continue mixing until fully incorporated.
Step 5: Incorporate the Wet Ingredients
In another bowl, mix together the sourdough starter, milk, lemon zest, and vanilla extract. Slowly pour this wet mixture into the stand mixer while blending on low speed. This combination not only enhances the flavor of your Sourdough Blueberry Buckle but also helps create that tender crumb you desire. Blend until the batter is smooth, taking care not to overmix.
Step 6: Combine Dry and Wet Ingredients
Gradually add the dry flour mixture into the wet batter in the stand mixer. Mix on low speed just until combined; you want to avoid overworking the batter, which can make the cake dense. By keeping it gentle, you’re ensuring a tender and fluffy outcome for your delicious Sourdough Blueberry Buckle.
Step 7: Add Blueberries and Layer the Batter
Toss the fresh or frozen blueberries in a teaspoon of flour to coat them lightly, which prevents them from sinking. In your prepared baking pan, pour half of the batter, spread it evenly, and then layer in half of the blueberries. Pour the remainder of the batter on top, then sprinkle the rest of the blueberries for added juiciness and flavor bites throughout the buckle.
Step 8: Sprinkle the Crumble Topping
Retrieve the chilled crumble topping from the refrigerator and evenly sprinkle it over the top of the Sourdough Blueberry Buckle batter. This crunchy layer will develop a beautiful brown crust as it bakes, adding a delightful contrast to the soft, moist cake beneath.
Step 9: Bake the Buckle
Place the pan in the preheated oven and bake for 45-50 minutes, or until the top is golden brown and a toothpick inserted into the center comes out clean. Baking time may vary depending on your oven, so keep an eye on the buckle as it cooks. The delightful aroma will fill your kitchen, signaling that your treat is almost ready.
Step 10: Cool and Serve
Once baked, remove the Sourdough Blueberry Buckle from the oven and let it cool in the pan on a wire rack for about 10-15 minutes. This cooling time allows it to set properly. Once cool enough to handle, slice and serve warm, or let it reach room temperature for a cozy dessert experience.

Sourdough Blueberry Buckle Recipe FAQs
How do I choose ripe blueberries for my Sourdough Blueberry Buckle?
Selecting ripe blueberries is essential for maximizing flavor! Look for plump, firm berries that are dimpled and deep blue in color. Avoid those with green or red spots and any that exhibit dark spots all over, as they may not be ripe. If you can, taste a few—sweetness is a good indicator of quality!
What is the best way to store leftover Sourdough Blueberry Buckle?
Store your Sourdough Blueberry Buckle in an airtight container at room temperature for up to 2-3 days for optimal freshness. If you chose to refrigerate it, it should last for about a week. Just be sure to cover it to keep it moist!

When you’re ready to enjoy it, thaw it in the fridge overnight or reheat directly from the freezer in the oven for a warm treat!
What should I do if my cake turns out dense?
If your Sourdough Blueberry Buckle ends up dense, it may be due to over-mixing during the batter preparation or using stale sourdough starter. To avoid this, mix the ingredients until just combined and ensure your sourdough starter is used within 48 hours of feeding. A gentle hand makes all the difference when creating that tender texture!
Can I make this recipe vegan or free of common allergens?
Certainly! To veganize your Sourdough Blueberry Buckle, substitute the egg with a flax egg (1 tablespoon of ground flaxseed mixed with 3 tablespoons of water, let sit for 5 minutes until gelatinous).
