Tastes Like a Fudge Brownie, Eats Like a Cookie
If you love the rich, fudgy decadence of a brownie but crave the handheld convenience of a cookie, this recipe is your dream come true. These cookies are deeply chocolatey, soft in the center, slightly crisp on the edges, and studded with melty dark chocolate chunks. The secret ingredient? Sourdough discard, which adds subtle tang, moisture, and depth—making these cookies irresistibly chewy and complex in flavor.
Perfect for bake sales, holiday trays, or late-night chocolate cravings, these brownie-style cookies deliver bold cocoa flavor with that crackly, shiny top you love in a classic brownie.

Instructions
Preheat Oven: Preheat oven to 350°F (175°C). Line baking sheets with parchment paper.
Mix Dry Ingredients: In a bowl, whisk flour, cocoa powder, baking soda, and salt until evenly combined.
Cream Butter & Sugars: In a separate large bowl, beat softened butter, brown sugar, and white sugar until light and fluffy (about 2–3 minutes).
Add Egg & Vanilla: Beat in the egg and vanilla extract until smooth.
Incorporate Sourdough Discard: Mix in sourdough discard until fully combined.
Combine Wet & Dry: Gradually add dry ingredients into the wet mixture. Mix until just combined.
Add Milk: Stir in milk to loosen the dough slightly for fudgier texture.
Fold in Chocolate: Gently fold in dark chocolate chips or chunks.
Chill Dough: Refrigerate dough for at least 30 minutes to enhance flavor and texture.
Bake: Scoop 2-tablespoon portions onto prepared baking sheets. Bake 10–12 minutes until edges are set but centers remain soft. Cool on pan 5 minutes before transferring to wire rack.
Tips

Don’t Overmix: Overworking the dough makes cookies tough.
Chill for Thickness: Chilling prevents excess spreading.
Use Good Cocoa Powder: High-quality cocoa deepens flavor.
Underbake Slightly: Centers should look slightly soft for fudgy texture.
Measure Flour Correctly: Spoon and level to avoid dense cookies.
Use Dark Chocolate: Enhances brownie-like richness.
Let Rest After Baking: They firm up as they cool.
Sprinkle Sea Salt: Adds gourmet contrast.
Store Airtight: Keeps them soft and chewy for days.
