In a medium sized bowl, or your stand mixer bowl, combine the cream cheese filling ingredients. Mix well until the powdered sugar is completely combined. Use a small cookie scoop to make rounded tablespoon sized dollops. Place on a parchment paper lined baking sheet and freeze for at least an hour.
Combine the cake mix, vegetable oil & eggs in a clean bowl. Refrigerate while your oven preheats to 350F.
Spray a medium sized cookie scoop with nonstick spray. Use a little bit of the cooking spray on your hands to prevent the dough from sticking. Scoop two balls of cookie dough and flatten them slightly with your palm. Place a frozen ball of cream cheese in between the two pieces of cookie dough and seal the edges.
Place the cookie dough on a parchment paper lined baking sheet - about 2 inches apart. Bake for 10-12 minutes or until the surface of the cookies is no longer glistening and has more of a satin appearance.
Allow the cookies to cool and place on a wire rack. To finish, melt about 1/2 of a bag of white chocolate chips & drizzle on top of the cooled cookies.
