Why You’ll Love This Recipe

Ingredients

You only need a handful of simple ingredients for these delightful little mounds!

  • 1 cup smooth peanut butter: Use your favorite creamy variety. Natural peanut butter can work, but sometimes separates, so standard creamy is usually the most reliable for texture here.
  • 11 ounces butterscotch chips: The key to that classic butterscotch flavor! One standard bag is usually 11 or 12 ounces, so just grab a bag.
  • 4 cups chow mein noodles: These crispy, crunchy noodles are the “hay” in our haystacks. Make sure they’re fresh and not stale for the best crunch.
  • 1 cup roasted peanuts (optional): If you love extra peanut flavor and crunch, toss these in! Use salted or unsalted depending on your preference. I personally love the little bit of salt the salted ones add!

How to Make It

Alright, let’s make some haystacks! This is seriously the easiest process ever.

  1. Grab a good-sized microwave-safe bowl. We’re going to melt our binding agents first.
  2. Toss the peanut butter and the butterscotch chips into that bowl.
  3. Now, we melt! Pop the bowl into the microwave. Heat in short bursts – think 20 or 30 seconds at a time.
  4. This is important: After each interval, take the bowl out and give the mixture a really good stir. Even if it doesn’t look fully melted, stirring helps the residual heat do the work and prevents burning. Keep microwaving and stirring until the mixture is completely smooth, glossy, and totally melted. It should be easy to stir with no lumps.
  5. Next, it’s time to add the crunch! Pour the chow mein noodles and the optional roasted peanuts into the bowl with the melted peanut butter and butterscotch.
  6. Gently, but thoroughly, fold everything together. Use a spatula or a sturdy spoon and make sure every single noodle and peanut gets coated in that glorious sweet and peanut buttery mixture. You want everything lovely and sticky!
  7. Line a couple of baking sheets or your counter space with wax paper or parchment paper. This is where our haystacks will set up.
  8. Using a spoon (or two spoons if you find it easier!), drop heaping spoonfuls of the mixture onto the prepared paper. You can make them big or small, uniform or rustic – it’s totally up to you! They don’t need to be perfect.
  9. Now comes the hardest part: waiting! Let the haystacks sit out at room temperature until they are completely cool and firm. This usually takes an hour or two, depending on how warm your kitchen is. Don’t rush it, or they’ll be soft and messy.
  10. Once they’re set, carefully peel them off the wax paper. Time to enjoy your easy, crunchy, delightful haystacks!

Substitutions & Additions

Want to mix things up? Here are a few ideas:

  • Different Chips: Not a fan of butterscotch? Try milk chocolate chips, semi-sweet chocolate chips, or even white chocolate chips instead. Or do a mix!
  • Nut Butter Swaps: Almond butter or cashew butter can be used, but they might alter the setting consistency slightly. Stick with peanut butter for the classic texture.
  • Add-ins: Get creative! Try adding mini marshmallows, chopped pretzels for extra saltiness, crispy rice cereal for more crunch, or even some flaky sea salt sprinkled on top before they set.
  • Nut-Free: For a nut-free version, use SunButter (sunflower seed butter) and omit the peanuts. Make sure your chips are also nut-free.

Tips for Success

  • Don’t Overheat: When melting the peanut butter and chips, use those short microwave intervals and stir, stir, stir! Overheating can cause the chocolate/butterscotch to seize or burn.
  • Even Coating: Take your time folding in the noodles and peanuts. You want every piece coated so the haystacks hold together and have flavor throughout.
  • Setting Time: Be patient! They really do need to set completely at room temperature to be firm enough to handle and stack. If your house is warm, they might take a bit longer.
  • Prep Ahead: While they are quick to make, you can measure out your ingredients ahead of time so you’re ready to go!

How to Store It

These haystacks keep really well! Once they are fully set, store them in an airtight container at room temperature. Layer them between sheets of wax paper if needed to prevent sticking. They should stay fresh and crunchy for up to 1-2 weeks, though honestly, they never last that long in my house!

If you want them to set faster, or if your kitchen is very warm, you can pop the baking sheets into the refrigerator for about 30 minutes to speed things up before storing them at room temp.

FAQs

Can I use crunchy peanut butter?

Yes, you absolutely can! Using crunchy peanut butter will just add another layer of texture with the peanut pieces already mixed in.

Can I use different kinds of noodles?

While chow mein noodles are traditional, you could experiment with other crispy rice noodles or even crushed pretzels for a different take, but the texture might be slightly different.

How long does it take for them to set?

At room temperature, they usually take about 1-2 hours to set completely. If you refrigerate them, they’ll be firm in about 30 minutes.

Are these gluten-free?

Traditional chow mein noodles are made with wheat, so this recipe as written is not gluten-free. You would need to find gluten-free crispy noodles or use a different gluten-free crunchy base (like gluten-free pretzels or crispy rice cereal) if you need a GF option.

Notes

Use short microwave intervals and stir frequently when melting to prevent burning. Ensure noodles and peanuts are evenly coated. Allow adequate setting time at room temperature (1-2 hours) or refrigerate for 30 minutes. Store completely set haystacks in an airtight container at room temperature for up to 1-2 weeks. Use wax paper layers to prevent sticking. Try milk or dark chocolate chips instead of butterscotch. Add mini marshmallows, chopped pretzels, or crispy rice cereal for variations.
