Hi, I just made chocolate-hazelnut spread, and I liked it!
Grind 100 g toasted hazelnuts, 10 seconds speed 10.  let cool.  set aside.
Heat 50 g heavy cream, 90 g whole milk, 1 tbsp powdered milk, and 10 g canola oil 3 minutes temp 80 speed spoon
add 150 g semisweet chocolate chips (ghirardelli) and let stand 1 minute.
mix 1 minute speed 1
add the ground hazelnuts and mix 10 seconds speed 7
It will not be as thick as canadian nutella, more like european Nutella.  although not as sweet as either of them, and you will definetly taste the hazelnuts... thats why I liked it
Hope you like it too!
