I bought Fage Greek yogurt 0% fat and I mixed in sugar free Torani chocolate syrup. It was pretty good. Still had a little aftertaste but I think if I add some Stevia drops it will completely remove that. Gonna make caramel yogurt next with Torani sugar free syrup.

I think that Stevia tends to make yogurt taste bitter but let us know how it turns out. I just mixed in some Mio drops and that worked pretty well. You can also mix Crystal Lite or sugar free jello powder.

I use mio also...it's some great stuff!

If you make your own yogurt at home instead of buying the yogurt, it will taste even better... When you make it homemade you can control how sour it is so it doesn't have that strong sour taste that many commercial yogurts have. Give it a go, you won't be sorry.
