I tried it yesterday and it turned out awesome. Creamy and rich, it tastes just like a good chocolate ice-cream. I made the mistake of trying to substitute the heavy cream with half and half at first, trying to cut down the fat, but it simply wouldn't foam. So it is important not to use substitution.
WOW!!! This was wonderful for something so easy, especially if you're a Nutella fan! Decadent but not too sweet. Just served it with a drizzle of chocolate sauce. I think it would be really great with strawberries or kiwis. Great dessert to impress dinner guests. Thanks Dee!
