First, you'll need some yogurt - duh! - and a few other ingredients like sugar, fruit, or honey to give it some extra flavor. The type of yogurt you use is up to you, but full-fat yogurt tends to work best for freezing because it's creamier and less likely to become icy.
Now, here's where things get really interesting. Did you know that freezing yogurt is basically like making ice cream, but without all the fancy equipment? You can even add in some crazy mix-ins like chocolate chips, nuts, or candy pieces to give it a fun twist.
