Fluffernutter Whoopie Pies

Kelly at Evil Shenanigans wanted to follow Top Chef: Just Desserts by doing each week’s challenges. I thought it was a cool idea but I missed the first challenge she did. That’s o.k. Once I watched last week’s episode  I knew what my ingredient was ..I just wasn’t sure what I wanted to do.

peanut butter whoopie pies are the perfect after school snack


Last week was the Bake Sale Challenge. If you will remember the contestant that got kicked out you will remember that she was kicked out over peanut butter cookies. Very uninspired peanut butter cookies. As soon as that happened I knew that I wanted to make peanut butter cookies that would make those judges sit up and take notice…not that I will ever meet them… but in my fantasy world they stumble across my blog and are blown away by my brilliant take on peanut butter cookies.


But I still wasn’t sure what I wanted to do. Peanut butter… yes… but what could I make that would be a best seller at a bake sale?

My kids always go for the biggest thing there so I knew it had to be supersized. And then I remembered one of my favorite foods when I was a kid and I knew what I was going to do. I googled the ingredients and did not come up with ONE recipe. Yay! This was a sign that I was on the right track, right? Fluffer-nutter whoopie pies. Massive peanut butter cookies with a marshmallow filling. What’s not to love?

And  poor Heather had wanted to do… whoopie pies.

I made the first batch of dough using a whoopie pie recipe from another site and exchanging ingredients. It was awful and I threw it out. It was frustrating because I knew I was going to lose my decent light….and I did.

I decided to use my own recipe as a base and adjust for the different ingredients. I knew that my recipe had the texture I was looking for; cakey and moist. So I started over.


These whoopie pies are moist and full of peanut butter flavor. The filling is sweet marshmallow. I considered adding sliced bananas or chocolate but never got there. The top of the cookie is sprinkled with turbinado sugar for extra flavor and crunch.

Try these. Perfect with a big glass of milk! You can make them smaller if you like. This recipe makes 8 whoopie pies if you use a 1/4 cup scoop for the cookie.

I don’t think the judges would have declined these. I think they would have had to take a cookie and milk break.
