You can get yogur/granola/fruit mixes like that at a Starbucks, Peet’s Coffee, and other similar places. At Whole Foods too!

Try taking vanilla Greek yogurt (any generic store brand will do), put it in the freezer for about an hour or two, take it out, add ground walnuts to it and some chopped up fruit (blueberries, strawberries, blackberries, whatever you prefer). Very good treat, like ice cream.

Yes; it would be simple to make. The brand that I suddenly recall was Yoplait.
Once I saw the maker of the yogurt that starts with a “CH ” interviewed so I went out and bought one and hated it . lol
