Ingredients
1/2cupUnsalted Butterat room temperature
3/4cupBrown Sugar(light or dark)
1largeEggat room temperature
1teaspoonPure Vanilla Extract
1.5cupsAll-Purpose Flour
1/2cupUnsweetened Dark Cocoa Powder
1teaspoonCornstarch
3/4teaspoonBaking Soda
1/8teaspoonSalt(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.
