Beat your cream cheese until it’s nice and smooth, about 2 minutes. Using a stand mixer works great, but you can also use a hand mixer with a bowl. Add in the brown sugar, vanilla extract, powdered sugar, and creamy peanut butter. Mix until it’s all smooth. Scoop the mixture into the middle of a large piece of plastic wrap. Roll it up into the plastic wrap and roll it into a ball. Place it into the freezer for an hour, or until the cheese ball is mostly firm. Dump the peanut butter chips and chocolate chips in a flat plate. Unwrap the cheeseball from the plastic wrap and roll it around in the chips until the cheese ball is fully coated in the balls. Press any extras into the empty spots. Place the cheese ball into the freezer for about an hour, or more, until its nice and firm. If you freeze it overnight you’ll need to remove it about 30 minutes before serving.
