Use the butter wrapper and coat the pyrex dish, set aside
In a large pot, melt entire stick of butter
When butter is melted add the mini marshmallows
When marshmallows are completely melted add the peanut butter & nutella.
Then add the Cheerios and mix well
Transfer Cheerios mix to buttered pyrex dish & set aside to cool
Drizzle melted chocolate over top of the Cheerios
For a healthier option, use almond butter or sunflower butter instead of peanut butter
And add nuts and dried cranberries to the cheerios mix.
