The first time I had Butterscotch Haystacks, they were tucked into a Christmas cookie box from my neighbor, and I could not believe the crunch and flavor! When she told me the secret was a bag of chow mein noodles, I was blown away, because they taste nothing like chow mein noodles. It's just creamy, peanut buttery goodness with the best crunch. For the holidays, I love adding mini M&M's to the top for a pop of color!

Ingredients for Butterscotch Haystacks
- Butterscotch chips: One 11-ounce bag gives these their buttery, caramel-like flavor.
- Creamy peanut butter: Adds smooth, nutty flavor and is the glue that holds the haystacks together.
- Chow mein noodles: One 12-ounce bag. They give the haystacks that hay-like look and all the crunch... and no, they don't taste like chow mein!
- Roasted peanuts: Add richer nutty flavor and a slightly different crunch.
- Mini M&M's (optional): My holiday touch for a pop of color on top.

How to make Butterscotch Haystacks
Prep the pans. Line two sheet pans with parchment paper.
Melt. Add the butterscotch chips and peanut butter to a large microwave-safe bowl. Microwave in 30-second increments, stirring between each, until the chips are melted and the mixture is smooth.
Stir in the crunch. Add the chow mein noodles and peanuts and stir until everything is coated.
Scoop. Drop heaping tablespoons of the mixture onto the prepared sheet pans. If you're using mini M&M's, sprinkle them on top right away while the haystacks are still soft so they stick.
Chill. Refrigerate for 15 to 20 minutes, until set. Enjoy!
Stephanie's tips for the best haystacks
- Go slow in the microwave. Butterscotch chips burn easily, and once they burn they turn hard and grainy. Stick to 30-second bursts and stir every time.
- Use fresh chow mein noodles. Fresh noodles give you the most crunch.
- Add toppings fast. Sprinkle the mini M&M's on before the haystacks start to set.
How to serve Butterscotch Haystacks
These are best served on their own once they've set. They're also perfect for gifting... pop a few in a clear bag tied with ribbon for holiday or party giveaways, or tuck them into a cookie box like my neighbor did. Need more ideas for your tray? Check out my Christmas Cookie Box Ideas.
Substitutions and variations
- Mini M&M's: Totally optional, but so fun for the holidays.
- Marshmallows or shredded coconut: Both can be stirred in for a little something extra.
- Toasted noodles: For even more crunch, lightly toast the chow mein noodles in a dry skillet before adding them. I haven't tested this one myself yet.
Butterscotch Haystacks FAQs
Why can't I microwave the butterscotch chips longer?
Butterscotch chips burn very easily, and when they burn they turn hard and grainy. Microwaving in 30-second intervals and stirring in between helps prevent that.
Can I add other mix-ins?
Yes! Marshmallows or shredded coconut both work, and mini M&M's on top are my favorite for the holidays.
Can I make them ahead of time?
Yes. Make them up to 2 days ahead for the best crunch. They'll keep for up to a week, but they start to get a little softer after the first few days.
How do I make sure they stay crunchy?
Use very fresh chow mein noodles and store the haystacks in an airtight container.
How to store Butterscotch Haystacks
Store in an airtight container or large zip-top bag at room temperature for up to 1 week. If your house runs on the warm side, keep them in the refrigerator instead.
