What do you do with a jar of Nutella in the cupboard after Christmas that you've had there to make chocolate truffles with that you didn't get around to making?
You eat it by the spoonful, of course.
Until better sense gets the better of you and you frantically google "recipes with Nutella" to save you from yourself.
Nutella brownies, recipe from here, they kindly provide the calorie, cholesterol and saturated fat content per bar: I suggest you carefully don't read this.
An excellent way to use up the Nutella, a lovely treat for my sweet-deprived children, but honestly, if you're into brownies in any way, not a patch on these.
