1-First, whisk the pudding mix, whipped topping, softened cream cheese, and milk together until you get a smooth, creamy dressing. This step builds the base that ties everything together, creating that signature cheesecake flavor. Make sure all lumps are gone for the best texture, and if it feels too thick, add a bit more milk to adjust.

2-Second, stir in the mini marshmallows gently, as they add a fun, chewy element to the salad. This helps distribute them evenly before adding the fruits. Next, fold in the berries one type at a time starting with strawberries, then blueberries, and finally raspberries to keep them intact and prevent any mashing.

3-Third, once mixed, chill the salad in the refrigerator for at least 1 hour; it can sit up to 48 hours for even better flavor as it thickens. This resting time lets the ingredients meld, enhancing the overall taste. For an extra touch, sprinkle optional crushed graham crackers on top just before serving to add crunch.
