Start by ensuring your cream cheese is at room temperature. If you forgot to take it out of the fridge, microwave it for about 10-15 seconds to soften it slightly.
In a mixing bowl, combine the softened cream cheese and mayonnaise. Using a spatula, blend them together until smooth and creamy.
Fold in the small diced sweet onion and freshly grated Parmesan cheese, ensuring everything is evenly distributed.
Sprinkle in the freshly ground black pepper and mix thoroughly until the dip is well combined and creamy.
Transfer the dip to a serving bowl, cover it with plastic wrap, and refrigerate for at least an hour before serving with dippers.
