🔪 Instructions:
1. Preheat Oven & Prep Pan:
-
Preheat oven to 350°F (175°C).
-
Line an 8×8-inch pan with parchment paper, leaving overhang for easy removal.
2. Melt Butter & Chocolate:
-
In a medium saucepan over low heat (or in a microwave-safe bowl), melt the butter and chocolate together until smooth.
-
Let cool slightly.
3. Whisk in Sugar & Eggs:
-
Add granulated sugar, brown sugar, and vanilla to the chocolate mixture.
-
Whisk in eggs, one at a time, until glossy and smooth.
4. Add Discard:
-
Stir in the sourdough discard until fully incorporated.
5. Finish the Batter:
-
Sift in cocoa powder, flour, and salt.
-
Fold gently until just combined — don’t overmix.
-
Stir in any mix-ins (chocolate chips, nuts, etc.).
6. Bake:
-
Pour batter into prepared pan and smooth the top.
-
Bake for 30–35 minutes, or until a toothpick comes out with moist crumbs (not wet batter).
-
Cool completely in the pan before slicing.
🍽️ Serving Tips:
-
Best texture is achieved after cooling fully (even better the next day!).
-
For extra decadence: top with a scoop of ice cream or a drizzle of ganache.
🧊 Storage:
-
Store at room temp in an airtight container for 3–4 days.
-
Freeze for up to 2 months (wrap individually for easy grab-and-go treats).
🔄 Variations:
-
Add 1 tsp espresso powder to deepen the chocolate flavor
-
Swirl in peanut butter, cream cheese, or raspberry jam before baking
-
Use gluten-free flour for a GF version (sourdough discard must also be GF)
