Ingredients for Sourdough Fudgy Chocolate Cookies

Wet Ingredients

• ½ cup unsalted butter, softened

• ¾ cup brown sugar

• ¼ cup white sugar

• ½ cup sourdough discard (unfed)

• 1 large egg (room temperature)

• 1 teaspoon vanilla extract

How to Make Fudgy Sourdough Chocolate Cookies

Step 1: Prepare the Oven

Preheat your oven to 175°C (350°F). Line a baking tray with parchment paper.

Step 2: Cream Butter and Sugars

In a large bowl, cream together butter, brown sugar, and white sugar until light and fluffy.

Step 3: Add Sourdough Discard

Mix in sourdough discard, egg, and vanilla extract until smooth and fully combined.

Step 4: Combine Dry Ingredients

In a separate bowl, whisk together flour, cocoa powder, baking soda, and salt.

Step 5: Make the Dough

Gradually add dry ingredients to the wet mixture. Mix just until combined—do not overmix.

Step 6: Fold in Chocolate

Gently fold in chocolate chips or chunks.

Step 7: Bake

Scoop dough (about 2 tablespoons per cookie) onto the prepared tray, leaving space between each cookie.

Bake for 9–11 minutes, until edges are set but centers look soft.

Step 8: Cool

Allow cookies to cool on the tray for 5 minutes before transferring to a wire rack. They will firm up while staying fudgy inside.

Tips for Ultra-Fudgy Cookies

• Slightly underbake for gooey centers

• Use dark cocoa powder for deeper flavor

• Chill dough for 20–30 minutes to prevent spreading

• Add a pinch of espresso powder to intensify chocolate taste
