Decadent, delicious low-fat frozen chocolate yogourt

I think the title pretty much says it all. I'd been looking for a yummy chocolate treat that wasn't too rich but still tasted good. Something that warranted the word "treat". And I found it here. Unfortunately the recipe calls for low-fat evaporated milk and I couldn't find a can that wasn't processed (mmm... dipotassium phosphate). But one of the comments had alternate instructions and they were even yummier than the original.

Home-made frozen chocolate yogourt

1 can low-fat sweetened condensed milk
1/2 cup dark chocolate (either chips or a broken chocolate bar)
3 tbsp cocoa powder
1 tsp vanilla extract
1 cup fat free plain Greek yogourt

Stir chocolate chips and condensed milk in a sauce pan over medium heat until chips are melted and blended in with the milk. Remove from heat and add cocoa and vanilla. Stir until blended then mix in yogourt. Cool.

At this point I spoon it into my ice cream machine (it's very thick) and let it mix for about an hour before putting it in the freezer. If you don't have an ice cream machine, just put it in the freezer immediately and remove to stir about every 10 to 15 minutes for the first hour. I find it needs to freeze for about 24 hours before it's thick enough so make it a day in advance.

If you're making this for a family, you might want to double it as it only makes about two or three bowls. I make this and plain vanilla ice cream so the kids have some choice with their treat (I will post that recipe tomorrow). Enjoy!
