These brownies are nearly fat free. You can substitute the plain yoghurt and vanilla with vanilla yoghurt which gives a better result but more sugar.
Altered ingredient amounts. I used soya plain yoghurt as I have a dairy intolerance - 07 Jun 2010 (Review from Allrecipes UK & Ireland)
great easy recipe, i used a fat free activia and they turned out really gooey and quite brownie like! i also added choc chips and mixed nuts to give them a bit of bite. Will be making them again! - 23 Feb 2011 (Review from Allrecipes UK & Ireland)
Used different ingredients. try using vanilla muller light instead as thats fat free but sweeter. - 06 Jun 2010 (Review from Allrecipes UK & Ireland)
