Peanut Butter Whoopee Pies —soft peanut butter cookies filled with peanut butter frosting and marshmallow fluff. A fluffernutter mashup.
These Peanut Nutter Whoopee Pies are s throwback mash of a fluffernutter sandwich and a whoopee pie. Traditionally whoopie pies are chocolate cookies with a vanilla shortening cream filling. Fluffernutters are peanut butter and marshmallow sandwiches made with white bread. I’ve made the sandwich cookie into peanut butter and filled them with peanut butter frosting and marshmallow fluff. It’s so yummy!
Peanut butter whoopee pie ingredients
Light brown sugar
These peanut butter whoopee pies are also called fluffernutter whoopee pies because of the mixing of peanut butter with marshmallow cream.
Whoopee pies instructions
To make the whoopee pies, mix together in a bowl the flour, salt, baking soda, and baking powder then set it aside. In another bowl beat the softened butter with both sugars, peanut butter, egg, and vanilla. Sift in the dry mix and blend on medium speed. Add the milk and mix until fully blended.
Scoop even mounds of dough onto a baking sheet. Bake for 9-11 minutes in a preheated 350-degree oven. Allow the cookies to cool for 5 minutes before carefully moving them to a wire rack to finish cooling.
In a clean mixing bowl beat the softened butter, salt, peanut butter, powdered sugar and vanilla on medium speed until smooth.
Fluffernutter whoopee pies
To make fluffernutter whoopee pies, spread the peanut butter frosting on half of the cookies and a tablespoon of marshmallow fluff on the other half.
Sandwich them together to form a delicious sandwich cookie.

I typically don’t like to leave negative reviews but I made these for my senior living resident’s dessert tonight and followed the recipe as stated. I used a small scoop, about a tablespoon, because I wasnt sure how much these would spread. They came out like little rocks. Thank God I only made two to see how big they would be. I scrapped the whoopie pie idea and baked the batter in a pan then cut them into bars, still, it was disappointing that my folks did not get the whoopie pie they were expecting. Not sure what happened here; I am a avid baker and all my ingredients are fresh.
Sorry the recipe didn’t go well for you. It was tested using proper measuring techniques. There are a number of things that can upset a recipe. Hope this post helps: https://www.ontysplate.com/how-to-measure-flour-properly/
Such a good cookie! Made these and they are irresistible! Thank you for your recipe, it’s great 👍
Thank you, Caitlin! So glad you enjoyed them.
How fluffy and chewy these whoopie pies look! Can’t go wrong with fluff and pb, absolutely adorable.
Oh. My. Yum! I love whoopie pies and I love peanut butter so this is like my dream dessert! I can’t wait to bake these. I may or may not share!
This fluffernut whoopie pie sounds so delicious, never made but now I am inspired 🙂
These whoopies look so fluffed up and tempting! Like you, I haven’t grown up eating these, but I totally get where these are coming from.
I’ll take a dozen! 😀 I love the idea of whipping up PB with marshmallow cream…what a heavenly combo! These whoopie pies look so good! They’re calling to me right now 😀
I haven’t made whoopee pies in about a thousand years, and reading this post, I’m not at all sure why. Regardless, I’m feeling inspired now. I LOVE the flavor combinations you have going on here but am wondering if you’ve ever tried other nut butters? I’d love to try these with almond butter, but am concerned that the consistency won’t be the same. Any advice?
Hi Rebecca. I have not tried any other but butter but I don’t think I would try it with almond butter personally. I could possibly consider cashew butter but that’s just my taste preference. If you decide to try with another but butter, please come back and let me know how it turns out!
How fun are these!?! My kids would be loving all the fluffernutter fun going on here, and pretty easy to whip up too!!
This is such a fun idea! I live in the town that Fluff was invented, we have a big festival every September, its a little ridiculous but a lot of fun. These fluffernutter whoopie pies will be a great addition to the fluff inspired eats available!
What a brilliant whoopie pie flavor! I grew up in central PA, home of the whoopie pie – but almost always just the standard chocolate cake with vanilla filling. I can’t wait to make this version!
Hmm yum! This pie looks soooo delicious! I am sure my son would love this. Can’t wait to go to the kitchen.
I grew up on whoopie pies so this post took me back!!! I’ve never made my own though and these steps to recreate look easy!! I can’t wait to make these for my kiddos!
I think your kids will love this recipe. And I’m all about simplicity so I hope the instructions reflects that. Thanks!
These whoopee pie cookies sound amazing! Love the fluffernutter flavor of them! My girls will love these!
