When Making These Peanut Butter Marshmallow Cookies, Here’s A Few Helpful Tips! 

This peanut butter marshmallow cookie recipes isn’t hard to make, but there are some things to consider to make it easier for you…

  • First of all, the first batches of cookies you bake, you should definitely time these precisely to get your timing down, because you don’t want to over-bake these cookies.  You won’t get the preferred texture and the goal is to make them soft and gooey-ish.
  • These are what I call jumbo cookies, so I used a 1/4 cup (ice cream scoop size) per cookie dough to make each cookie, so if you make these smaller, adjust your time and refer to step 1 .
  • Use parchment paper on your baking trays and bake them @ 350 degrees @ 10-12 minutes, to get the marshmallows toasty but not all the way caramelized and melted.
  • The cookies will still be baking once they are pulled from the oven, but DO NOT remove them from the baking sheet for 5-10 minutes.  They are still setting up and may appear under-cooked and will tear apart if you try to do this immediately.
  • Coat your spatula with a non-stick spray to take them off the baking sheet to transfer them to a baking rack or foil.  The marshmallow that is exposed on the bottom of the cookie, can catch on the spatula if you don’t grease it, which will break up the cookie.
  • Once cooled completely, transfer to a sealed airtight container or zip-lock bag at room temperature.

  1. Hi Pamela! I would say approx 48 if you are doing a tablespoonful per cookie, but I made these super-sized so I’m making a guess. I think what you are doing is a great contribution! I know they will love these and I hope you all raise lots of money! xo

  2. Was wondering how many normal size cookies these should yield. I hope to bake these for the youthgroup’s annual Chocolate Festival the Saturday before Valentine’s Day. It is their biggest fundraiser of the year towards money for their summer mission work trip to help low income and seniors do repairs on their homes. I took the very first group over 20 years ago and its an amazing experience but at almost 60 years old my days of sleeping in school band rooms (I’m usually the only one wise enough, or with enough aches and pains, to bring a cot, the kids get sleeping bags on the floor) and traveling with groups of teenagers is long over. This is how I help now. It helps to know in advance about how many I can expect from a batch of dough to be prepared to make several if need be. Many thanks.

  3. I love fluffernutter too! LOL! I love changing out cookies with different ingredients and I love the idea of changing out the caramel with chocolate chips. It all sounds good to me. Thank you so much for commenting and making them again for the holidays! xo

  4. Made these last year. Changed out the chocolate chips with caramel bits. Amazing!!! Recipe made 14 huge cat head cookies. Special request to be made this year too! Might try white choc chips or toffee chips this time! But then again, why mess with a good thing!! Thanks again from a southern girl all about the fluffernutter

  5. I’m a sucker for anything with peanut butter – adding marshmallow I imagine makes them positively addicting! Thanks for the tips and tricks – I can’t wait to make these!
