These no-bake Haystack Cookies are crunchy, sweet, and made with only four ingredients: peanut butter, butterscotch, chow mein noodles, and honey-roasted peanuts.
In a microwave-safe bowl, combine butterscotch chips and peanut butter. Microwave in 20-second intervals, stirring well after each, until smooth (about 40 seconds total). Be careful not to overheat. Melting is happening even outside of the microwave!
In a large bowl, add peanuts and chow mein noodles. Pour the melted butterscotch mixture over them and gently fold with a spatula until well coated.
Use a spoon to drop the mixture onto a parchment-lined sheet pan, forming 2–2.5-inch mounds. Top with mini chocolate chips or a pinch of flaky sea salt, if you like.
Let the cookies cool completely until the butterscotch hardens, either at room temperature or in the freezer for about 20 minutes. Enjoy!

Notes
Storage: Store the cookies in a sealed container in the fridge for up to a week to keep them fresh. For longer storage, freeze them in layers separated by parchment paper, and they’ll stay good for up to 3 months.
