Peanut Butter Crunch Marshmallow Bars FOR PRESIDENT!!  Am I right?  It’s probably just my unabashed love of all things peanut-buttery getting the better of me again.

I’m just not myself around peanut buttery treats.

Or, maybe I am, and “myself” is a big giant peanut butter loving hound?  If you’re one of those people that is a hater of peanut butter….you may have found yourself in the wrong place.

We, at The Salty Marshmallow like PB in our sandwich cookies, our non sandwich cookies, and inside of biscuits.

Either way, you guys, these bars are worth getting completely weird obsessed over.


These remind me of a “back in the day” kind of treat.  These are something that your awesome, sweet, adorable, grandma would serve you.  They are a really special, super rich, indulgent kind of bar.

Grandma wasn’t watching her figure when she made treats like this.  Neither are we!


What is awesome about these?  Besides, ya know, everything.

They are NO BAKE!!

The bottom layer is like a mixture between a peanut butter cookie and peanut butter fudge.  A lot of peanut butter bars call for graham crackers.  These are extra special with vanilla wafers!

The chocolate layer is just melted Nestle Crunch Baking Bits (you can use the cut up candy bars if you’d like).  It gives the perfect crunchy texture to this bar.  Like eating a big fat soft and cruncy candy bar!

The marshmallows….well, they’re for fun.  They’re my “namesake” so, there they are!  They add another fun layer as well.

Soft peanut butter, crispy chocolate…..squishy marshmallow?  Something like that!

Get these on your fall no bake dessert list!
