• 2 teaspoons (10 g) vanilla extract

👩‍🍳 Instructions

1. Preheat the oven to 350°F (176°C). Line a 9×9-inch baking pan with parchment paper.

2. Melt the butter in a small saucepan over low heat. Stir in the cocoa powder, vanilla extract, and chocolate chips until smooth. Remove from heat and let cool slightly.

3. Using an electric mixer, beat the eggs, granulated sugar, and brown sugar together in a large bowl for 7–10 minutes, until thick and pale.

4. Add the cooled chocolate mixture and sourdough discard to the bowl. Mix on low just until combined.

5. Add the flour and salt, stirring gently until just incorporated — do not overmix.

6. Pour the batter into the prepared pan, smoothing the top. Bake for 35–40 minutes.

7. Let the brownies cool fully in the pan before slicing into squares.
