Notes
Cream cheese: Over the years, I've made this recipe with full-fat cream cheese, 1/3-less fat cream cheese, and Greek yogurt cream cheese. All three types of cream cheese have worked well. However, I don't recommend using fat-free cream cheese in this recipe.
Non-dairy whipped topping: I've used Cool Whip and Tru-Whip in this recipe.
Greek yogurt: Plain, nonfat Greek yogurt, 2%, or full-fat Greek yogurt will work. Full-fat or lite sour cream will also work.
Sweetened condensed milk: Regular or fat-free sweetened condensed milk will work.
