Nutella: you will have left over Nutella. Keep it in the fridge for a midnight snack, use with the cookie dough to make thumbprint biscuits or eat it straight away (therefore avoiding having to make a decision about what to do with the leftovers)
Cookie Dough: you will only need 2/3's of this recipe. Use the rest to make thumbprint cookies with the left over nutella.
