Decoration Tips: For a fun and polished presentation, sprinkle a few extra chocolate chunks on top of each cookie ball before baking. This will give the cookies a deliciously gooey look once they come out of the oven. You can also lightly dust the baked cookies with powdered sugar for an extra touch of sweetness or drizzle some melted chocolate over the top for a more indulgent finish. If you want to add a bit of flair, try rolling the cookie dough balls in chocolate sprinkles or crushed nuts before baking for added texture and flavor.
Ingredients:
- 1/2 cup (115g) softened butter
- 1/4 cup + 2 tbsp (75g) granulated sugar or caster sugar
- 1/3 cup + 1 tbsp (79g) soft brown sugar
- 1 large egg (room temperature)
- 1 1/2 tsp vanilla extract
- 1 1/2 cups (187g) all-purpose flour
- 1 tsp cornflour
- 1/2 tsp baking soda
- 1/4 tsp baking powder
- 1/2 tsp salt
- 2 1/2 tbsp all-purpose flour (for vanilla cookie dough)
- 3 tbsp cocoa powder (for chocolate cookie dough)
- 175g chocolate chunks, divided for both cookie doughs
Instructions:
- Prepare the dry ingredients: In a medium bowl, whisk together the flour, salt, baking soda, and baking powder. Set this mixture aside.
- Cream the butter and sugars: In a separate large mixing bowl, add the softened butter, granulated sugar, and brown sugar. Mix by hand or with a spatula until the ingredients are well combined and creamy.
- Add egg and vanilla: Crack in the egg and add the vanilla extract. Whisk the mixture by hand until it becomes light in color and smooth in texture.
- Combine wet and dry ingredients: Gradually add the dry ingredients to the butter mixture, stirring just until the flour streaks disappear. Be careful not to overmix, as this can affect the texture of the cookies.
- Divide the dough: Split the cookie dough into two equal parts. To one half, add 2 1/2 tablespoons of flour and mix. To the other half, add 3 tablespoons of cocoa powder and mix until fully incorporated. This creates the vanilla and chocolate doughs.
- Add chocolate chunks: Divide the chocolate chunks between the two doughs, mixing them into both the vanilla and chocolate doughs evenly.
- Form marble cookies: To create the marble effect, scoop out small half-tablespoon-sized balls of each dough. Place one vanilla dough ball, followed by a chocolate dough ball, then repeat with another vanilla and chocolate ball. Gently press and roll the dough together to form one large dough ball, ensuring the flavors swirl together.
- Chill (optional): For extra thick cookies, refrigerate the dough balls for at least 1 hour. If you’re short on time, you can skip this step and bake them immediately.
- Bake: Preheat your oven to 175°C (350°F). Place the cookie dough balls on a parchment-lined baking tray, spacing them a few inches apart as the cookies will spread slightly. Bake for 10-13 minutes, or until the sides are firm and the center is soft and slightly underdone. This will give the cookies a perfect chewy texture.
- Cool: Once baked, remove the cookies from the oven and let them cool on the tray for 7-10 minutes. This allows the cookies to firm up without losing their chewy center.
Enjoy your thick, soft, and chewy marble cookies, packed with chocolatey goodness in every bite!
