Toss the noodles and chips in the slow cooker and get a crunchy, sweet treat the grandkids will go crazy for. It's the easiest candy you'll ever make!
This slow cooker butterscotch haystacks recipe is the kind of no-fuss candy you toss together when the grandkids are on their way and you want something fun, crunchy, and sweet without turning the oven on. It leans on pantry staples—chow mein noodles and butterscotch chips—and lets the slow cooker do the work. Haystacks have been a Midwestern church-basement and holiday-tin classic for years, but here we skip the stovetop and melt everything low and slow so you can walk away, answer emails, or switch a load of laundry while the candy base comes together.
Serve these butterscotch haystacks piled on a platter or in a big tin lined with parchment for easy sharing. They’re great with a cup of coffee or hot cocoa for the adults, and a glass of cold milk for the kids. I like to set them out alongside a bowl of fresh fruit or simple salty snacks like pretzels or popcorn to balance the sweetness. They also travel well for potlucks, school events, or holiday cookie exchanges—just let them set completely before layering in containers with wax or parchment paper between layers.
Slow Cooker Butterscotch Haystacks
Servings: 24
Ingredients
1 (11–12 oz) bag butterscotch chips 1 cup semisweet chocolate chips (optional but recommended for balance) 2 tablespoons unsalted butter 1/2 cup creamy peanut butter 1 teaspoon pure vanilla extract 1/4 teaspoon fine sea salt (omit if using salted peanuts) 4 cups dry chow mein noodles 1 cup salted roasted peanuts (optional, for extra crunch) Sprinkles or flaky sea salt, for topping (optional)
Directions
Lightly spray the inside of your slow cooker with nonstick cooking spray or line it with a slow cooker liner for easier cleanup.
Add the butterscotch chips, semisweet chocolate chips (if using), unsalted butter, and peanut butter to the bottom of the slow cooker, keeping them in an even layer so they melt consistently.
Cover the slow cooker and cook on LOW for 45 to 60 minutes, stirring every 15 minutes, until the chips are completely melted and the mixture is smooth and glossy. Turn the slow cooker to WARM once everything is melted so it doesn’t scorch.
Stir in the vanilla extract and sea salt until fully combined.
Add the dry chow mein noodles and salted peanuts (if using) directly into the slow cooker. Gently toss and fold with a heat-safe spatula until all the noodles and nuts are evenly coated in the butterscotch mixture. Be patient here so you don’t crush all the noodles—you want that signature haystack look.
Line two large baking sheets with parchment or wax paper. Using a spoon or small cookie scoop, drop heaping tablespoons of the coated noodle mixture onto the prepared sheets, forming loose “haystacks.”
If desired, immediately sprinkle the tops with sprinkles or a tiny pinch of flaky sea salt while the haystacks are still tacky.
Let the haystacks cool at room temperature for about 1 hour, or until firm and set. If your kitchen is warm, you can speed this up by placing the trays in the refrigerator for 20 to 30 minutes.
Once set, transfer the haystacks to an airtight container. Store at room temperature for up to 5 days, or in the refrigerator if your home is very warm. Layer with parchment or wax paper to prevent sticking.
Variations & Tips
For a nut-free version, skip the peanuts and add extra chow mein noodles or swap in sunflower seeds or pumpkin seeds. If you love classic butterscotch flavor without chocolate, use only butterscotch chips and increase the amount to 16 ounces, keeping the rest of the recipe the same. For a more grown-up twist, stir in 1/2 cup of shredded coconut or chopped pretzels with the noodles for extra texture and a salty-sweet balance. You can also use half chow mein noodles and half crispy rice cereal for a lighter crunch. For holiday haystacks, top them with seasonal sprinkles or colored candy melts drizzled over the top once they’ve set. If you’re short on time, spread the coated noodle mixture in an even layer on a parchment-lined sheet pan, chill until firm, then break into clusters instead of scooping individual haystacks. To prep ahead, melt the chips and peanut butter in the slow cooker earlier in the day, then switch to WARM and stir in the noodles and peanuts right before you’re ready to scoop so the mixture stays workable.
