When I make yogurt and want a decadent creamy one I add cream to the finished mix along with any flavourings. I would add the seed of a vanilla bean along with the cream and voila a very creamy rich yogurt, with a lot of calories
I am working on a vanilla bean scented yoghurt at the moment…so stay tuned…could be the answer to all your dreams! (but you should dream bigger if that is true!)
