These peanut butter no bake cookies are one of those dangerously easy recipes you’ll find yourself making again and again because they take just minutes to throw together and taste so unbelievably good. The combination of creamy peanut butter, crunchy noodles, chewy marshmallows, and sweet butterscotch makes them totally different from classic no bake cookies—and my kids love them so much they’ve started making batches themselves for quick after-school treats!

• Only 4 Simple Ingredients – You can make an entire batch with pantry staples and zero complicated steps, making these perfect for last-minute dessert cravings.
• No Stove Fuss or Baking – Unlike many no bake cookie recipes, there’s no boiling sugar mixture or candy thermometer involved—just melt, mix, and scoop.

Ingredients in Marshmallow Peanut Butter No Bake Cookies

Butterscotch Chips – Add rich sweetness and help create the smooth coating that holds everything together.

Peanut Butter – Brings creamy texture, salty-sweet flavor, and helps bind the cookies into clusters.

Chow Mein Noodles – Give the cookies their signature crunchy texture and fun, crispy bite.

Mini Marshmallows – Add soft, chewy pockets of sweetness that make these cookies extra irresistible.

Tips for making Marshmallow Cookies

• Control the heat like it’s your job – Melt the peanut butter and butterscotch chips just until smooth. If it gets too hot, the mixture can turn greasy and the marshmallows will melt into nothing instead of staying chewy little pockets.
• Let the mixture cool slightly before marshmallows – Stir them in too early and you’ll lose that gooey marshmallow texture entirely. A short 1–2 minute pause keeps them soft and intact.
• Fold, don’t overmix – Once the noodles and marshmallows go in, gently fold just until coated. Over-stirring breaks the noodles and makes the texture less “crunchy cluster” and more “crumbly pile.”
• Work quickly when scooping – The mixture sets fast as it cools, so have your wax paper ready and scoop right away for the best cookie shape and consistency.

How long are no-bake peanut butter cookies good for?

These cookies will stay fresh at room temperature in an airtight container for about 3–4 days, or up to a week if you keep them in the fridge (they’ll be a bit firmer there).

They also freeze well—store them in a sealed container or freezer bag with parchment between layers, and they’ll keep for about 2–3 months. Just let them sit at room temperature for a few minutes before eating so they soften back up and get that perfect chewy-crunchy texture again.

Can I use regular marshmallows instead of mini marshmallows?

Yes, just chop them into smaller pieces so they mix in evenly and don’t clump together.

Do I need to cook the mixture for a long time?

Nope—just melt the peanut butter and butterscotch chips until smooth. Overheating can make the texture greasy and mess with the marshmallows.

Can I substitute the chow mein noodles?

You can swap in something crunchy like pretzels or cornflakes, but chow mein noodles give the classic light, crisp texture these cookies are known for.

Why did my cookies turn out sticky or too soft?

They likely weren’t cooled enough before scooping or the marshmallows were added while the mixture was too hot, causing them to melt instead of stay fluffy.
