Equipment

  • Mixing Bowl
  • Baking Sheet
  • Parchment Paper

Ingredients

Ingredients

  • 1/2 cup Unsalted Butter at room temperature
  • 3/4 cup Brown Sugar (light or dark)
  • 1 large Egg at room temperature
  • 1 teaspoon Pure Vanilla Extract
  • 1.5 cups All-Purpose Flour
  • 1/2 cup Unsweetened Dark Cocoa Powder
  • 1 teaspoon Cornstarch
  • 3/4 teaspoon Baking Soda
  • 1/8 teaspoon Salt (optional)

Instructions

  • Preheat your oven to 350°F (175°C). Line a baking sheet with parchment paper or a non-stick baking mat.
  • In a large mixing bowl, cream together the room-temperature butter and brown sugar until light and fluffy (about 2 minutes with a hand mixer).
  • Add the egg and vanilla extract, and mix until fully combined.
  • Sift together the flour, dark cocoa powder, cornstarch, baking soda, and salt (if using) into a separate bowl.
  • Gradually add the dry mixture to the wet ingredients, mixing on low speed or by hand until just combined. Don’t overmix!
  • The dough will be thick and fudgy. Scoop tablespoon-sized portions onto your prepared baking sheet, spacing about 2 inches apart.
  • Bake for 8–10 minutes, just until the edges look set but the centers look slightly underdone. Do not overbake—these cookies finish setting as they cool!
  • Let the cookies cool on the baking sheet for 5 minutes before transferring them to a wire rack to cool completely. Enjoy warm or at room temperature!

Notes

Store cooled cookies in an airtight container at room temperature for up to 5 days. For longer storage, freeze in a zip-top bag or freezer-safe container for up to 3 months.
