How to Make Sourdough Brownie Recipe

Step 1: Prepare Your Ingredients

Gather all ingredients at room temperature. This helps everything mix smoothly, avoiding lumps and ensuring even baking.

Step 2: Melt Butter and Mix with Sugar

Gently melt your butter in a saucepan over low heat or the microwave, then whisk in the sugar until fully combined and glossy for that sweet base.

Step 3: Add Sourdough Starter and Eggs

Stir in your sourdough starter discard along with the eggs one at a time, ensuring the mixture is uniform and slightly airy.

Step 4: Combine Dry Ingredients

In a separate bowl, sift together flour, cocoa powder, and salt to avoid any clumps, then gradually fold them into the wet mixture.

Step 5: Add Flavors and Mix-ins

Incorporate vanilla extract and any extras like nuts or chocolate chips, gently blending to distribute without overmixing.

Step 6: Bake to Fudgy Perfection

Pour the batter into a greased or parchment-lined pan and bake at a moderate temperature until the edges set but the center is still slightly gooey, usually 20-25 minutes.

Pro Tips for Making Sourdough Brownie Recipe

  • Use discard that’s active but not bubbly: It’s perfect for adding tang without overpowering the batter.
  • Don’t overmix the batter: Mixing just until combined ensures chewy, tender brownies instead of tough ones.
  • Watch the baking time closely: Slightly underbaking results in fudgier brownies, but don’t leave them too wet.
  • Line your pan with parchment paper: Makes removal and cleanup easy while preserving the brownie’s edges.
  • Try chilling the batter: Refrigerate for 30 minutes to improve texture and make cutting neater.

How to Serve Sourdough Brownie Recipe

Garnishes

Top your brownies with a dusting of powdered sugar, a sprinkle of sea salt, or a dollop of whipped cream to add visual appeal and a burst of flavor.

Side Dishes

Pair with vanilla ice cream, fresh berries, or a drizzle of caramel or raspberry sauce to complement the rich chocolatey taste and contrast textures.

Creative Ways to Present

Serve brownies in bite-sized squares on a rustic wooden board, stack with layers of cream for a brownie parfait, or sandwich between two brownie layers with frosting for an elegant twist.

Make Ahead and Storage

Storing Leftovers

Keep brownies in an airtight container at room temperature for up to 3 days to maintain moisture and flavor, or refrigerate if your kitchen is warm.

Freezing

Wrap individual pieces tightly in plastic wrap and place in a freezer-safe bag; they freeze well for up to 3 months and thaw quickly at room temperature.

Reheating

Warm brownies in the microwave for 10-15 seconds or in a low oven for a few minutes to revive that fresh-baked feeling and gooey texture.

FAQs

Can I use any sourdough starter discard for this recipe?

Yes, any plain sourdough discard works well, but avoid ones with added flavorings or fruit to keep the brownie flavor balanced.

Will the brownies taste sour because of the starter?

The tang is subtle and adds complexity but does not overpower the chocolate; it’s more of a background note that enriches the overall flavor.

Can I make this recipe vegan?

Absolutely! Substitute eggs with flax or chia eggs, and replace butter with coconut or vegan butter to keep the fudgy texture intact.

How fudgy will the brownies be?

Very fudgy, thanks to the sourdough discard moisture and careful baking time; they should be moist but set on the edges with a gooey center.

Can I add mix-ins like nuts or chocolate chips?

Yes, you can easily fold in nuts, chocolate chips, or even dried fruit to customize the texture and flavor to your liking.
