Measure out Rice Krispies cereal into a large bowl and set aside. In a medium saucepan over medium heat, melt butter and marshmallows together until smooth, once marshmallows and butter have melted together add Nutella and stir until well mixed.

Pour marshmallow mixture over the cereal. Stir to coat evenly. Press into a greased pan.

To make topping, heat nutella and chocolate chips in a medium sauce pan over medium low heat until smooth.

Spread over the top of Rice Krispies treats. Put in the fridge and let it set up. Once they have set, cut into them and eat them up... YUM!
