Step 1: Prepare the Cookie Cake

• Preheat your oven to 350°F (175°C). Grease a 9×13-inch baking pan or line it with parchment paper for easy removal.
• In a large mixing bowl, combine the red velvet cake mix, softened butter, eggs, and vanilla extract. Mix until well combined and a dough forms.
• Gently fold in the white chocolate chips (or chocolate chips) until evenly distributed.
• Pour the cookie dough into the prepared baking pan and spread it evenly.

Step 2: Bake the Cookie Cake

• Place the pan in the preheated oven and bake for 20-25 minutes, or until a toothpick inserted into the center comes out clean or with a few moist crumbs.
• Remove from the oven and let the cookie cake cool in the pan for about 10-15 minutes before transferring it to a wire rack to cool completely.

Step 3: Prepare the Cream Cheese Frosting

• In a mixing bowl, beat the softened cream cheese and butter together until smooth and creamy.
• Gradually add the powdered sugar, mixing until well combined.
• Add the vanilla extract and mix well. If the frosting is too thick, add milk a tablespoon at a time until you reach your desired consistency.

Step 4: Frost the Cookie Cake

• Once the cookie cake is completely cooled, spread the cream cheese frosting evenly over the top.
• Optionally, decorate with sprinkles or additional white chocolate chips for a festive touch.
