Mix the cream cheese with the mixer for about 1 minute until creamy. Then add the marshmallow fluff and stir again until everything is mixed. Finally stir in the peanut butter.
Once everything is mixed, you can serve the dip either immediately or the next day. Small pretzels, crackers and biscuits or normal pretzels are recommended for dipping.
350 g is the equivalent of a small glass of peanut butter. I took the crunchy version. You can vary the amount - depending on whether you prefer it salty (more peanut butter) or sweeter (less peanut butter).
