¾cup(93.75g)all-purpose flourweighed in grams or spooned and leveled
½cup(43g)cocoa powder
½teaspoonsalt
1cup(180g)semi-sweet chocolate chipsdivided (⅔ in the batter, ⅓ for topping)
Instructions
Preheat oven to 350°F and line a 9-inch square pan with parchment paper.
In a large bowl, whisk together the eggs, egg yolk, and brown sugar until light and airy (4-5 minutes).
In a microwave-safe bowl, melt the butter with the ½ cup of chocolate chunks. Let it cool slightly, then whisk in into the egg-sugar mixture for 1-2 minutes. Stir in the sourdough discard.
In a medium bowl, whisk together the flour, cocoa powder, salt, and ⅔ cup of chocolate chips. Using a spatula, fold the dry ingredients into the wet ones just until the flour streaks disappear.
Spread the brownie batter into the prepared pan, then sprinkle the remaining ⅓ cup of chocolate chips on top. Bake until the edges are set and the center has a shiny, crackly top (22-27 minutes).
Let the brownies cool completely in the pan on a wire rack, then remove from the pan, slice into squares, and enjoy!
Notes
Chocolate: I like to use high quality chocolate chunks or chopped baking chocolate for the melted chocolate in this recipe, but good chocolate chips like Guittard or Ghirardelli (>60% cacoa) can be used instead.Toothpick Test: The brownies are done when a toothpick inserted into the center comes out with a few gooey crumbs.Storage: Store cooled brownies in an airtight container at room temperature for 1 week or in the freezer for 3 months.Nutrition: The provided nutrition information is an estimate, the calorie accuracy is not guaranteed.
