Ingredients
Main Ingredients
- 1/2 cup salted butter, softened
- 3/4 cup brown sugar, lightly packed
- 1 large egg, room temperature
- 1 teaspoon vanilla extract
- 1 1/2 cups all-purpose flour, spooned and leveled
- 3/4 teaspoon baking soda
- 1/4 teaspoon baking powder
- 1/4 teaspoon salt
For Vanilla Dough
- 2 tablespoons all-purpose flour
For Chocolate Dough
- 2 tablespoons natural cocoa powder
Optional
- Flaky sea salt, for topping
Instructions
- Preheat Oven: Preheat your oven to 350°F (176°C) and line a large aluminum baking sheet with parchment paper to prevent sticking and ensure even baking.
- Cream Butter and Sugar: In a large bowl, cream softened butter and brown sugar together until the mixture turns light and fluffy, about 2 minutes, indicating that air has been incorporated for a soft cookie texture.
- Add Egg and Vanilla: Mix in the egg and vanilla extract thoroughly until fully incorporated, creating a smooth batter base for the dough.
- Combine Dry Ingredients: In a separate bowl, whisk together the 1 ½ cups flour, baking soda, baking powder, and salt. Gradually add this dry mix to the wet ingredients, stirring until just combined to avoid overmixing which can toughen cookies.
- Divide Dough: Split the cookie dough evenly into two bowls, measuring with a digital scale for accuracy. Add 2 tablespoons of flour to one bowl for vanilla dough, and 2 tablespoons of cocoa powder to the other for chocolate dough, mixing each well.
- Shape Dough Balls: Use a small cookie scoop or spoon to portion out 12 dough balls from each dough type. For uniform size, weigh each ball with a kitchen scale.
- Create Marble Effect: Roll one vanilla and one chocolate dough ball together between your palms to form a swirled, marbled cookie dough ball. Repeat for all dough balls to form 12 total marbled balls.
- Arrange on Baking Sheet: Place 6 marbled cookie dough balls on the lined baking sheet at a time, spacing each about 2 inches apart to allow for spreading during baking.
- Bake Cookies: Bake in the preheated oven for 10-12 minutes. For a softer, slightly underbaked texture, opt for 10 minutes; for a crispier yet chewy edge, bake for 12 minutes until edges turn lightly golden.
- Cool and Store: Remove cookies from the oven and let them cool on the baking sheet for a few minutes before transferring them to a wire rack or plate. Store cooled cookies in an airtight container for up to 5 days or freeze to preserve freshness.
Notes
- Using a kitchen scale ensures all dough balls are the same size for even baking and consistent cookies.
- Do not overmix the dough after adding flour to prevent tough cookies.
- Tweaking bake time allows you to customize texture between soft and chewy or slightly crispy edges.
- If desired, sprinkle flaky sea salt on top before baking to enhance flavor contrast.
- Store cookies in an airtight container at room temperature; freeze leftovers for extended storage.
