Instructions:

1st Step

In a large mixing bowl, combine the chow mein noodles, peanuts (if using), and mini marshmallows (if using). Toss them together gently to distribute the ingredients evenly.

2nd Step

Over low heat, combine the creamy peanut butter and butterscotch chips in a medium saucepan. Keep stirring until everything is blended and smooth.

3rd Step

Combine the butterscotch and peanut butter and pour them over the chow mein. Gently fold and mix until all the noodles are uniformly coated, using a spatula or wooden spoon.

4th Step

Prepare a parchment paper-lined baking sheet or tray. Drop the mixture by the spoonful onto the parchment paper, or use your hands to do so. Form them into little mounds that resemble haystacks.
