Mix the softened cream cheese and white sugar in a large mixing bowl using an electric mixer on medium speed for 2-3 minutes until smooth and creamy.

Gently fold in the Cool Whip with a spatula for a light, airy texture, careful not to overmix.

Add the strawberries, blueberries, and raspberries gently into the creamy mixture, preserving their shape.

Transfer the mixture into a serving bowl or individual cups and chill in the refrigerator for at least 1 hour before serving.
