Ingredients
- 6 tablespoons unsalted butter
- 1/2 cup granulated white sugar
- 1/2 cup light brown sugar, lightly packed
- 1/2 tablespoon pure vanilla extract
- 1/4 teaspoon instant espresso powder, dissolved in 1/2 teaspoon hot water (optional)
- 1 large egg yolk
- 1/4 cup sourdough starter, you can use active starter or unfed discard
- 7 tablespoons unsweetened cocoa powder
- 1/4 cup all-purpose flour
- 1/2 teaspoon salt
- 6 tablespoons walnuts, chopped; or chocolate chips (optional)
Instructions
- Prep. Preheat the oven to 350F. Line an 8.5 by 4.5-inch loaf pan with parchment paper.
- Make the batter. Melt the butter, white sugar, and brown sugar together in a large bowl in the microwave or in a double boiler. Whisk until the sugar is fully dissolved (this is the key step for crackly tops!), and then let it cool for a couple minutes. Whisk in the vanilla, dissolved espresso powder, and egg yolk, and then the sourdough discard until smooth. Add the cocoa powder, flour, and salt, and whisk to combine, being careful not to over-mix. If you’re adding the walnuts chocolate chips, stir them in now.
- Bake. Transfer the batter to the prepared pan and bake until the brownies are set along the outside and shiny in the center, about 40 minutes.
- Cool. Cool completely before cutting and serving.

Notes
- Double Batch: To make a double batch, use 2 egg yolks (don't be tempted to use 1 whole egg instead). Bake it in an 8 by 8-inch pan, and note that it'll likely need 10 to 15 minutes longer in the oven.
- Storage: Once they're cool, individually wrap each brownie and pop them into an airtight container. Store them at room temperature for up to 4 days, in the fridge for up to 1 week, or in the freezer for up to 3 months.
