Peanut Butter Whoopie Pies
I grew up visiting the Pennsylvania Dutch Country as a child. Whoopie Pies are a classic dessert among the Pennsylvania Amish. They’ve become more popular in recent years and I’ve seen them pop up all over the place.
Last night I went out to dinner with a few of my girlfriends from college. I had some of these Peanut Butter Whoopie Pies waiting in the car in a lunch bag with ice packs. After dinner, we moseyed over to Starbucks for coffee and I whipped out my whoopie pies for dessert. A chorus of “Tar, these are really good!” ensued. I may have blushed a little.
What is a Whoopie Pie?
The official definition is “a dessert or snack made from two soft cookies, typically chocolate, with a creamy filling sandwiched in between.”
I skipped over the traditional chocolate version and went straight to peanut butter. And I don’t regret it one bit.
“Pennsylvania, Maine, Massachusetts, Virginia and New Hampshire all claim to be the birthplace of the whoopie pie.” – Wikipedia
Wherever they came from they are delicious. The first whoopie pie I clearly remember eating was in New Hampshire at a cute little country store while visiting my husband’s aunt. That was chocolate with marshmallow filling. Yum!
How to Make a Whoopie Pie?
Whoopie Pies are very easy to make. They are made from a thick, cakey batter that produces big soft cookies. My trick is using a cookie scoop to keep them a uniform size. This makes finding a pair that match much easier. Once you mix up the batter, just scoop the cookies and bake.
Next, mix up the filling. Cool the cookies, add some filling, and give them a top. Done!

Is peanut butter powder the same as peanut butter flour?
Pretty much. They can be used interchangeably.
Could you use cashew flour instead of peanut flour?
I have not baked with cashew flour myself but I think any nut flour would work in these.
Taryn can I get your ratio of your blend of sugar substitutes that you use please?
Hi Mary, it is linked in the post and you can find it here: joyfilledeats.com/sweetener
These spread out and are flat. The dough looked firm enough. The only change I made was regular milk instead of almond. Maybe if the recipe was by weight instead of volume it would have turned out? Bummer.
I’ve been slowly converting my recipes to offer weight but I have to do each individually. Did you use the sweetener listed? I don’t think just swapping the milk would make them spread so much.
Would these do okay if frozen? I want to make them, but I can’t go crazy. I LOVE peanut butter desserts and I WILL go crazy.
Yes. I’d wrap them individually in plastic wrap to avoid freezer burn.
in the recipe you say 1/2 cup sugar free sweetener or my sweetener, does that mean 1/2 cup or your sweetener? I have made your sweetener but have not used it yet.
Normally yes. This recipe was developed with erythritol though so you may need less. I’d try 1/2 the amounts listed. You can always make the filling sweeter if the cookies are lightly sweetened. Grinding my sweetener to a powder is recommended for icing.
Would this work with sunbutter for a peanut allergy?
Very tasty but I’m not sure if I did something wrong. The filling was too grainy. I think I will use powdered sweetener instead.
Same with mine
I want to try making these but I want to try to make my own peanut flour. Can I do this with regular salted peanuts? Some of these ingredients are so expensive. I would rather use the stuff I have on hand.
Thank you!
You can try but they press the oil out of peanut flour to make it drier. It might be too wet if you grind it yourself. Also, I’d try with unsalted peanuts or the cookies may end up too salty. Be careful when grinding the peanuts to stop as soon as they are finely chopped or you’ll end up with peanut butter.
Hi so I was just wondering about the cream filling it you are using peanut flour or are you using peanut butter powder? In The recipe it says powder in one part and then flour in the other part. Could you clarify? Thanks.
I just used the flour for the filling because I didn’t catch it in time hopefully it will turn out OK
As long as you are buying peanut butter powder without added ingredients they are basically the same thing. Either will work. https://www.nationalpeanutboard.org/news/in-nutshell-peanut-flour-vs-powdered-peanut-butter.htm
Anything peanut butter sounds like a good idea to me. Can’t wait to try!
These turned out amazing!!! So delicious! Thank you for sharing
Just did a batch of those delicious whoopie pies!!! OMG! It was easy to do! BUT peanut butter flour is very expensive in Quebec 8$ for 200gr, so I cant pig out… but I enjoy them the same :)))
I’m glad you liked them 😀
Can I use almond flour instead of coconut ?
Yes, but you will need a little more. I would try using 3/4 of a cup. If it looks too wet add more almond flour by the tablespoon until it looks like my photos.
These Whoopie pies were fantastic! They satisfy my peanut butter craving and were simple to make.
