Begin by ensuring that your cream cheese is at room temperature. Microwave it for about 10-15 seconds if needed.
In a mixing bowl, combine the softened cream cheese, lemon zest, lemon juice, and lemon extract (if using). Beat until creamy.
Gently fold in the marshmallow crème with a spatula or mix on low speed until well combined.
Taste and adjust sweetness with more marshmallow crème or powdered sugar, and add more lemon zest or juice if desired.
Optional: Chill in the refrigerator for about 30 minutes before serving for enhanced flavor.
Transfer to a serving bowl and arrange fresh fruits around the dip for serving.
