Fage chocolate frozen yogurt = epic fail

I used my Bzz Agent coupons to bur the Fage Greek yogurt and followed a recipe I found online.

- Fage Greek Yogurt- 0%, 24 oz
- Granulated Sugar, .75 cup
- Cocoa, dry powder, unsweetened, 6 tbsp
- Vanilla Extract, 1 tbsp

- Combine Ingredients in a Bowl

- Chill Mixture in Refrigerator for an Hour

- Churn in Icecream maker as per instructions until set.

This tasted absolutely disgusting.  I even added some chocolate chips to help it taste better.  It did not help.  It tasted so sour and tangy.  

Miss V wouldn't eat it and I ended up tossing it out.
