In a small bowl, mix all ingredients for crusts together until moist. Divide evenly between 4 serving dishes and press into the bottoms and up the sides about half an inch. Set aside.
In a large bowl, whip cream with powdered sugar and vanilla until stiff peaks form. Spoon out of mixing bowl and set aside. Place cream cheese, brownie mix and milk into same mixing bowl the cream was just in and whip until smooth. Gently fold in half the whipped cream.
Spoon or pipe over top the crusts. Top with remaining whipped cream and garnish with mini chocolate chips if desired. Refrigerate until ready to serve.
