Since I'm trying to lose weight, I tweaked this idea from a Weight Watcher friend to include greek yogurt - delicious and actually good for me. Very adaptable, add complimentary fruit or nuts to create your favorite.
Stir yogurt and cocoa powder together until well blended.
Stir in cool whip.
Fold in almonds and mini marshmallows.
If you are careful, you can do all this in the original yogurt container. Cover with plastic wrap and place in freezer. Check after 30 minutes by stirring. If it is ice cream consistency, it's ready to eat! If it's over frozen, just place it in the fridge until it's thawed to the desired consistency.
This is very adaptable. You can add fruit and/or nuts to your favorite flavor and have a single serving of frozen delight that you can eat guilt free!
