Chocolate Fluffernutter Whoopie Pies! Dark, chocolate mini cakes with an amazing peanut-buttery, marshmallow-y frosting sandwiched between. A match made in heaven!
Whoopie pies, cream pies, sandwich cookies, I don’t care what you call them, just call me when you make them!
If you are a sandwich cookie lover, try these Oatmeal Sandwich Cookies, Lemon Shortbread Cookies or Brownie Sandwich Cookies.

Simply bake up a batch of my chocolate whoopie pies (recipe included) and then put together this fluffernutter buttercream frosting to sandwich between the “pies”.
Whoopie Pie Ingredients
First you need to make up your “pies” and these are the simple ingredients:
- Boiling Water | this actually “blooms” the cocoa
- Unsweetened Cocoa Powder | I used Dutch Processed cocoa powder (sifted after measuring, if lumpy)
- Baking Soda | added with the boiling water and coco powder to activate it al
- All-purpose Flour |I use unbleached organic, all-purpose flour
- Baking Powder | no aluminum is my preference
- Kosher Salt | brings out all the flavors!
- Brown Sugar | I use light, never tried dark but I think it would work
- Butter | I used salted butter, make sure it’s soft
- Egg | I use large for my baking, eggs give whoopie pie discs that light, cakey like texture.
- Vanilla Extract |Pure is the best, but use what you have or make your own!
- Sour Cream | Brings great moisture and texture to the whoopie piece
How to Make Fluffernutter Frosting
- Marshmallow Creme or Fluff | a must use for the fluffer in the frosting
- Creamy Peanut Butter | I used all-natural peanut butter
- Butter | softened, you are making a buttercream, see real butter
- Vanilla Extract | adds depth to the frosting
- Kosher Salt | Yes, salt, just a bit!
- Powdered Sugar |also known as confectioners sugar or icing sugar
- Milk or Cream |a binder that gives the buttercream it’s smooth creaminess
This frosting would also be fabulous piped atop these rich, fudgy brownies or these espresso brownie bites.

How to Make the Fluffernutter Frosting
- Whip your butter until light and fluffy, about 2 minutes. Then add marshmallow cream, peanut butter, salt and vanilla, mixing until combined.
- Add powdered sugar and milk alternately on low speed. Once incorporated, increase speed to medium-high and beat until light and fluffy, about 4 minutes.
- Using a medium scoop, place a heaping scoop of fluffernutter filling on the “bottom” of a whoopie pie, place the matching “pie” on top, gently pressing down to fill the pie.

Recommended Tools
- Half Sheet Cookie Pan | I love this set as it comes with a cooling rack as well! USA pans are my favorite pan!
- Parchment Paper | This helps with clean up, but also allows the whoopie pie cakes to bake up evenly.
- Medium Cookie Scoop | This is key for matching, even pies, plus it works great for scooping the fluffernutter frosting equally.
- Large Batter Bowl | This is my personal favorite, I love that it has a lid.
- Spatula | for helping to mix as well as scraping all of that goodness out of the bowl!
How Do You Store Whoopie Pies
I like to individually wrap my whoopie pies with plastic wrap and store them in the freezer, then you can pop them in a lunch box, they’ll thaw by lunch time.
They will keep in an airtight container for 3-5 days, or wrap individually and toss in the refrigerator up to 7 days.

Funny thing is, I’m not even a cake lover, but these, little portable, handheld pies can make me swoon.
I’m sorry and you’re welcome!
Oh and if you want to stay all Classic New England, then please try my Classic Maine whoopie pies with traditional marshmallow buttercream.
These are New England approved by my husband’s family in Maine and New Hampshire!

it says how to make the frosting above the recipe then in the recipe it has how to make it and they are different directions. One says to add the powdered sugar at the end with the milk, the other is adding the peanut butter and milk last. Very confusing!!
Hi Lisa, sorry about that – for the frosting it doesn’t really matter, just add the ingredients and whip it all really well until light and fluffy, I’ll go in and make that easier to understand.
These look absolutely divine!
Thank you Julie! An apt description!
I made these for my co-workers. I put them out at 9 am, and by 10 they were gone, and I had to print out the recipe because everyone kept asking for it.
They are easy to make, but everyone now thinks I am some kind of great baker! I have since been asked to make them for a fundraiser to support a local horse rescue.
Another fabulous recipe, Kathleen. We loved the Fluffernutter Whoopie pies! We’ll enjoy them for Christmas with the family, although Jeff and I had a preview tasting tonight to be sure they were okay! LOL.
I love it!! So glad you enjoyed them Carol!!
