Not exactly the same. Are you sure it was sour cream and not cream cheese?

yes I am sure about that

I need a no bake dessert recipe for Saturday. With the temp going to be almost a hundred here in SD, I am trying not to make it hotter

1. Pudding/sour cream/milk would make something of a pudding consistency with a rich vanilla taste. There are lots of no bake cheesecake recipes on www.allrecipes.com ...... but they do have cream cheese .

bengardening, talking of cheesecake, have you ever made the Milnot no bake cheesecake? My aunt used to make this dessert, and I love it. Going to try it soon here. Milnot is no longer available in most places, but the recipes I find online explain how to use other canned milk brands.

Check this out. It's Mr Food no bake cheesecake. I use a lot of his recipes.

I found the following recipe by listing all the ingredients on the google search line. I did write cream cheese first and then the rest of the ingredients. I tried to find it without the cream cheese but it never came up. There is no milk listed either.

Here is one that uses Greek yogurt instead of sour cream but it does require baking:
