How to Make Brown Butter Sourdough Discard Chocolate Chip Cookies
Ingredients:
- 1 cup unsalted butter
- 1 cup light brown sugar (packed)
- 1/2 cup granulated sugar
- 1 large egg + 1 large egg yolk
- 1/2 cup sourdough discard (unfed)
- 1 tablespoon vanilla extract
- 2-1/3 cup all-purpose flour
- 1 teaspoon baking soda
- 1/2 teaspoon baking powder
- 3/4 teaspoon salt
- 1/2 teaspoon ground cinnamon
- 1-1/2 cups dark or semi-sweet chocolate chips or chopped chocolate (plus extra for topping)
- Flaky sea salt (for garnish, optional)
Directions:
- Melt the butter in a saucepan over medium heat. Stir and swirl occasionally until it foams, then turns golden brown and smells nutty. Scrape all the browned bits into a large mixing bowl. Let it cool for 10–15 minutes.
- Add brown sugar and granulated sugar to the brown butter and whisk to combine.
- Add the egg, egg yolk, and vanilla extract and whisk until smooth and glossy.
- Stir in the sourdough discard until fully incorporated.
- In a separate bowl, whisk together the flour, baking soda, baking powder, salt, and cinnamon.
- Add the dry ingredients to the wet ingredients and stir with a spatula or wooden spoon until just combined. Fold in the chocolate chips or chunks.
- Cover and refrigerate the dough for at least 2 hours or up to 72 hours. Chilling is essential for thicker, more flavorful cookies.
- When ready to bake, preheat oven to 350°F and line baking sheets with parchment paper. Scoop dough into 2-tablespoon-sized balls and place 2 inches apart.
- Bake for 10–12 minutes or until the edges are golden and the centers still look slightly soft.
- Immediately after baking, press extra chocolate chips on top and use a large round cookie cutter or glass to gently "scoot" the cookies into perfect circles, if desired.
- Cool on the baking sheet for 5 minutes, then transfer to a wire rack. Sprinkle with flaky sea salt if using. Allow to cool completely.
