Mix all ingredients for the cheesecake cream together in a medium mixing bowl, using a hand blender or a whisk, until smooth.
Add the lemon juice to the banana pieces and mix carefully until the bananas are completely covered. This will help prevent browning.
Place all the prepared fruit into a large serving bowl. Fold the cheesecake cream gently in with the fruit until evenly mixed. Serve as soon as possible.
Notes
Substitution options:
Cool Whip or whipped cream
Sour cream for plain Greek yogurt
Honeydew or Gaila melon for cantaloupe. Do not use watermelon. It's too watery and will make everything mushy.
Fresh mandarin oranges - remove all skin. It can be tough to chew.
For an even quicker option, swap in coconut Greek yogurt mixed with powdered sugar to taste in place of the cheesecake cream mixture.
