3-Ingredient No-Bake Haystack Cookies
These no-bake haystack cookies need just three ingredients and about ten minutes of hands-on time. They are the kind of treat you can make when a craving hits and you do not want to turn on the oven.
Crispy chow mein noodles coated in melted butterscotch and peanut butter, then mounded into little clusters. They set up into crunchy, salty-sweet bites in under an hour.
Why These Cookies Are a Weeknight Win
I keep a bag of chow mein noodles in the pantry just for this. When I need dessert in a hurry, this is the recipe I reach for.
The combination of rich butterscotch and creamy peanut butter melts into a glossy coating that clings to every crunchy noodle. There is no mixer, no oven, no waiting for butter to soften.
Ingredients
- 1 cup butterscotch chips: Classic base; use good-quality chips for the smoothest melt.
- ½ cup creamy peanut butter: Avoid natural peanut butter or the cookies will not set firmly.
- 3 cups chow mein noodles: Look for the plain crunchy kind, not the fried noodles packaged with seasoning.
Variations / Substitutions
- Swap the butterscotch chips: Use semisweet, milk, or white chocolate chips for a different flavor, or try peanut butter chips for double peanut taste.
- Use a different crunchy base: Broken pretzel sticks, crushed cornflakes, or crispy rice cereal work well, though the texture will change a bit.
- Add a crunch: Stir in a handful of salted peanuts or slivered almonds after the noodles are coated.

How to Make Haystack Cookies
Step 1: Melt the Butterscotch and Peanut Butter
Line a baking sheet with parchment paper. In a medium microwave-safe bowl, combine the 1 cup butterscotch chips and ½ cup peanut butter. Microwave in 30-second bursts, stirring with a spatula after each one, until the mixture is smooth and fluid. This takes about 1 minute total, but go slowly to avoid scorching.
The mixture will look separated at first, then come together into a glossy, caramel-colored sauce. It is ready when no lumps remain and the peanut butter has melted in completely.
Step 2: Stir in the Noodles
Add the 3 cups chow mein noodles to the melted mixture. Fold gently with the spatula until every noodle is coated. Work quickly here, because the warm mixture starts to thicken as it cools.
The noodles will crackle a bit as you fold, which is normal. You want a thick, sticky coating that clings to each strand, not a puddle of sauce.
Step 3: Scoop and Set the Haystacks
Drop heaping tablespoon-sized mounds of the coated noodles onto the prepared baking sheet. Use two spoons to push the mixture off, or use your fingers lightly moistened with water. Press them lightly into rough haystack shapes. Let the cookies set at room temperature for about 30 minutes until firm, or pop the tray in the fridge for 15 minutes to speed it up.
Once set, the cookies will be crunchy and hold their shape. Sprinkle a tiny pinch of flaky salt on top right after scooping, if you like, for a sweet-salty finish. Serve them straight from the baking sheet or pile them into a bowl.
A Few Tips for Perfect Haystacks
- Do not over-microwave the butterscotch chips, or they can seize and turn grainy. Short bursts and plenty of stirring keep the melt smooth.
- If the mixture becomes too stiff to fold, return the bowl to the microwave for 5 to 10 seconds, just enough to loosen it.
- Shape the haystacks with a light hand. Loose, airy mounds stay crunchier than tightly packed clusters.
- These set best in a cool, dry kitchen. High humidity can keep them slightly soft, so on a damp day, chill them in the fridge.
- To make a double batch, melt the chips and peanut butter in a saucepan over low heat, stirring constantly, for more control.
Scale the recipe up for a crowd:
| Batch Size | Butterscotch Chips | Peanut Butter | Chow Mein Noodles |
|---|---|---|---|
| Single | 1 cup | ½ cup | 3 cups |
| Double | 2 cups | 1 cup | 6 cups |
| Triple | 3 cups | 1½ cups | 9 cups |
Storing Leftover Haystacks
- Room temperature: Keep them in an airtight container, layered between parchment if needed, for up to 5 days. They stay crunchy and hold up well.
- Refrigerate: If your kitchen is warm, store them in the fridge for up to 1 week. The chill firms them even more, though they will soften slightly when they come back to room temp.
Frequently Asked Questions
Why did my haystack cookies fall apart?
The coating likely was not hot enough or not stirred until fully smooth, so it did not bind the noodles. Make sure the butterscotch and peanut butter are completely melted and combined before adding the noodles.
Can I use crunchy peanut butter?
Yes, you can. The cookies will have a bit of peanut crunch in the coating. Creamy peanut butter gives the smoothest texture, but crunchy adds a nice salty bite.
My mixture turned grainy. What happened?
The butterscotch chips overheated in the microwave. Next time, use shorter bursts and stir well between each one. If it happens, try stirring in a teaspoon of warm peanut butter to smooth it out, though the texture may still be a little off.
