Hard to find whole milk yogurt these days. I like the Cascadian Fresh brand because it uses only fruit to sweeten, no sugar, but the rare stores that do carry it even more rarely have the whole milk version.
You can’t find whole milk yogurt? Then do like me and make your own. It’s super easy! See this thread for a discussion:
Good old Dannon plain yogurt is made from whole milk. It’s available at Walmart around here. I was thinking it was a common national brand but maybe not.
There is a brand called Liberate’ which is a whole fat yogurt. It is yummy.
