How do I go about making Giant Multi-Flavor Cookie?
Here's a recipe for Giant Multi-Flavor Cookie:

Ingredients:

Cookie Dough Base

• 1 1/2 cups light brown sugar, packed
• 1 cup granulated sugar
• 1 teaspoon salt
• 1 cup unsalted butter, 2 sticks, melted
• 2 large eggs
• 1 teaspoon vanilla extract
• 2 1/2 cups all-purpose flour
• 1 teaspoon baking soda

Chocolate Chip Cookie Dough

• 2 tablespoons chocolate chips

Peanut Butter Cookie Dough

• 1 tablespoon peanuts, halved
• 1 tablespoon peanut butter

White Chocolate and Macadamia Nut Cookie Dough

• 1 tablespoon white chocolate chip
• 1 tablespoon macadamia nut

Chocolate Candy Cookie Dough

• 2 tablespoons chocolate candy

Double Chocolate Cookie Dough

• 1 tablespoon chocolate chips
• 1 tablespoon cocoa powder

Caramel and Pretzel Cookie Dough

• 1 tablespoon caramel chew, chopped
• 2 tablespoons pretzel piece

Instructions:

1. Make the base cookie dough. In a large bowl, whisk together the brown sugar, granulated sugar, salt, and butter until a paste has combined with no lumps.
2. Whisk in the egg and vanilla, beating until light ribbons fall off the whisk.
3. Sift in the flour and baking soda, then fold the mixture with a spatula, being careful not to overmix. This will cause the gluten in the flour to toughen, which will result in cakier cookies.
4. Divide the dough evenly between 6 medium bowls.
5. Make chocolate chip cookie dough by adding the chocolate chips to the first bowl. Mix well and set aside.
6. Make peanut butter cookie dough by adding the peanuts and peanut butter to the second bowl. Mix well and set aside.
7. Make white chocolate macadamia nut cookie dough by adding the white chocolate chips and macadamia nuts to the third bowl. Mix well and set aside.
8. Make chocolate candy cookie dough by adding chocolate candies to the fourth bowl. Mix well and set aside.
9. Make double chocolate cookie dough by adding chocolate chips and cocoa powder to the fifth bowl. Mix well and set aside.
10. Make caramel and pretzel cookie dough by adding chopped caramel and pretzels to the sixth bowl. Mix well and set aside.
11. Line a 10-inch (30 cm) cast iron skillet with parchment paper. Make a triangular shape with the chocolate chip cookie dough and press into 1/6 of the pan. Repeat with the remaining doughs.
12. Preheat the oven to 350°F (180°C).
13. Chill the pan for at least 30 minutes, up to overnight.
14. Bake the cookie for 30-45 minutes or stick a toothpick into the center of the cookie and the toothpick comes out clean
15. Cool the cookie for 10-15 minutes before slicing and serving.
