1In a large bowl, beat the cream cheese and butter together until combined. Then add in the chocolate cake mix, peanut butter, brown sugar, and powdered sugar and beat until combined.
2Place the mixture on a large piece of plastic wrap. Bring up all the corners of the plastic wrap and wrap into a ball. Freeze the ball for about 1 1/2 hours or until it is firm enough to keep its shape.
3Place the peanut butter chips on a flat plate and roll the unwrapped cheese ball in the peanut butter chips. Make sure to press the peanut butter chips into the cheese ball until it is fully covered.
4Place the ball on a serving dish, cover with plastic wrap and freeze the cheese ball for another 2 hours or overnight. If frozen overnight, thaw for 20-30 minutes before serving. Serve with Vanilla Wafers, graham crackers, fruit, or other cookies.
