Prepare the Dough
Divide your chocolate chip cookie dough into a mixing bowl.
Add black food dye to the chocolate chip dough and mix until evenly colored.
Divide your sugar cookie dough into a separate bowl.
Add orange food dye to the sugar cookie dough and mix until evenly colored.
Create the Swirl
Take small pieces of both the black chocolate chip dough and the orange sugar dough.
Gently roll them together in your hands to form a ball, creating a swirl effect.
Repeat this process for each cookie, using equal amounts of both doughs.
Bake the Cookies
Line a 9x13 baking sheet with parchment paper.
Place the dough balls on the baking sheet, spacing them evenly.
Press Halloween sprinkles onto the tops of each cookie.
Bake at 350°F (175°C) for 10-12 minutes, until the cookies are slightly golden at the edges.
Let the cookies cool on the baking sheet for 5 minutes before transferring to a wire rack to cool completely.
