1. Line an 8- x 8-inch pan with foil; spray foil with cooking spray.
2. Whisk together condensed milk and cake mix in a microwave-safe bowl.
3. Add white chocolate chips, and microwave in 30-second intervals until completely melted, stirring after each interval. Cool 2 minutes.
4. Gently fold in half of candy sprinkles; immediately pour into prepared pan. Sprinkles may bleed if over-mixed.
