Melt marshmallows and butter in an large microwave safe bowl.
Add nutella and stir well.
Pour in cereal and mix well...it's a bit tough!
Pour into a greased 9x13 pan.
When set, cut into squares and top with a spread of nutella.
Optional: Top each with sea salt and a piece of crisp bacon.
If you REALLY like bacon you could also mix some in with the cereal!
