Beat cream cheese, peanut butter, powdered sugar, brown sugar, and vanilla until smooth and creamy, about 2 minutes.
Fold in mini Reese’s Pieces, mini chocolate chips, and crushed peanut butter cups gently with a spatula.
Transfer to plastic wrap, shape into a ball, wrap tightly, and chill for 1 hour until firm.
Mix the coating ingredients in a shallow dish: Reese’s Pieces, chocolate chips, and peanut butter cups.
Unwrap, roll the cheese ball in the coating, and press gently. Let sit for 10 minutes before serving with crackers, cookies, or fruit.
