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 ¼ 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.

Holy Cow!!  Are you ready to bite into bits of gooey toasted marshmallow and an abundance of milk chocolate chips, Reese's peanut butter cups and peanut butter chips in yummy, soft and buttery peanut butter cookies?

You'll soon see why they're called OMG Peanut Butter Marshmallow Cookies!
