In a mixer, combine:
1 cup Nutella
1 cup Sugar
1/2 tsp milk
The dough is pretty crumbly. If your dough is super dry you can add another 1/2 tsp milk. However, try hand kneading for a minute first. I pulled out a handful at a time to knead and form into dough balls on the tray.
I have always heard it's best to make these small-ish cookies because they are chewy. I had dough balls around 1 tbsp in size. Normally I can fit 12 on my tray but I fit another row of 3 with this recipe & size.
Bake at 350 degrees for around 16 minutes. I use a energy star gas oven and always seem to need to bake things for a longer amount of time than anyone else. You know your oven best, just keep an eye on it!
These are a delicious, chewy, brownie-like cookie with a wonderful flavor. They lasted less than a day here!
