My sister made this super easy Nutella cookie recipe the other day - only 3 ingredients, plus optional ingredients such as nuts and chocolate chips.
1 cup of Flour
1 cup of Nutella
* 1/4 cup of nuts or chocolate chips (optional)
Preheat the oven to 350°F.
Mix all of the ingredients together, add in nuts such as crush walnuts and chocolate chips.
Bake for approx. 8-10 minutes.
