Method
Preparation
- Preheat your oven to 350°F (175°C).
- Line a 9x13-inch baking pan with parchment paper or grease it lightly.
- In a large mixing bowl, whisk together your melted butter and sugar until smooth. Then add in the cocoa powder, vanilla extract, and salt, mixing until well combined.
- Crack in the eggs one at a time, whisking well after each addition.
- Stir in the sourdough starter until well blended, followed by the flour. Mix gently until no streaks of flour remain.
- If using, fold in the semi-sweet chocolate chips.
- Pour the brownie batter into your prepared pan and spread it evenly.
Baking
- Bake in the oven for 25-30 minutes, or until a toothpick inserted in the center comes out with a few moist crumbs.
Cooling
- Allow the brownies to cool in the pan before lifting them out using the parchment paper.
- Cut into squares and enjoy!
Notes
For optimal freshness, store brownies in an airtight container at room temperature for up to 3 days. Freeze for longer storage, lasting up to 2 months. To reheat, thaw at room temperature or microwave for 10-15 seconds.
