For Chocolate Dough (to be added to half of the base dough)
2tbspCocoa Powder
1-2tspMilk(only if needed for piping)
Instructions
In a large bowl, beat softened butter and icing sugar with a hand mixer or stand mixer fitted with a paddle attachment on medium speed for 3–4 minutes until mixed. Add vanilla and beat again.
Add flour, and salt. Beat on low until a soft dough forms.
Divide the dough into two equal portions.
To one portion, add cocoa powder and 1 tsp milk. Mix gently until combined. Add more milk only if needed for piping.
Fill a piping bag fitted with a 1M star nozzle, placing vanilla and chocolate dough side by side for a swirl effect.
Pipe onto a parchment-lined baking sheet, leaving enough space between cookies.
Pipe onto a parchment-lined baking sheet, leaving enough space between cookies.
Bake in a preheated oven at 180°C (350°F) for 9–12 minutes, until edges are lightly golden.
Let cookies rest on the baking sheet for 2 minutes, then transfer to a wire rack to cool completely. Repeat with remaining dough, chilling between batches if needed.
Notes
Butter: Use softened butter, not melted. It should leave a gentle indentation when pressed but still hold its shape.
Milk: Add only with the cocoa powder — adding too much will make the dough too soft to pipe.
Piping Tip: A large star nozzle like Wilton 1M gives the classic bakery swirl.
Chilling: Helps cookies hold their shape while baking.
Baking Tip: Do not pipe new batches onto a warm baking tray. Always use a cool tray to prevent the cookies from spreading too much in the oven.
Storage: Store cooled cookies in an airtight container at room temperature for up to 1 week, or freeze for longer storage.
This recipe yields about 20–24 cookies, depending on the swirl size (about 1.5 to 2 inches each).
