I had been wanting to purchase muffin top pans for a long time. I was elated when I found them on sale at my recent TJ Maxx. Much to Lloyd’s chagrin, I’ve yet to use them for their intended purpose. Luckily, I got creative and used them to make some whoopie pies. Thick, luscious, creamy peanut butter filled banana whoopie pies, to be exact.
Peanut Butter Banana Whoopie Pies
Ingredients
- 1 1/2 cups all-purpose flour
- 1/2 cup bread flour
- 1 teaspoon baking soda
- 1/2 teaspoon salt
- 4 tablespoons unsalted butter, room temperature
- 4 tablespoons vegetable shortening
- 3/4 cups light brown sugar
- 1 teaspoon vanilla extract
- 2 large eggs
- 3 very ripe bananas, mashed
Directions
-
Preheat oven to 350 degrees F.
-
In a small bowl whisk together the all-purpose flour, bread flour, baking soda, and salt.
-
In the bowl of a stand mixer combine the butter, vegetable shortening, light brown sugar, and vanilla. Beat on medium speed for about 3 minutes with the paddle attachment, until light and fluffy.
-
Add the eggs one at a time, and stir just until combined.
-
Alternate adding the flour mixture and the mashed bananas. Stir to combine between each addition and scrape down the sides of the bowl if necessary.
-
Fill whoopie pie pan (I used a muffin top pan) with the mixture. Alternatively, you can pipe circles onto a baking sheet lined with parchment paper or a Silpat.
Salty Peanut Butter Woopie Filling
- 3/4 cup creamy or crunchy peanut butter
- 3/4 cup (6 tablespoons) unsalted butter, at room temperature
- 3/4 cup confectioners’ sugar
-
1/2 teaspoon salt
-
In a small bowl beat together the peanut butter and unsalted butter on low speed until smooth and creamy.
-
Add the confectioners’ sugar and salt, beat on low just until combined then increase speed to medium and beat until fluffy, about 4 minutes.
-
Fill one side of half of the whoopie pies with mixture, and top with the other halves.
Because my pies came out so thick, I doubled the peanut butter mixture so that the whoopie to filling ratio was more like 2:1. It was a beautiful ratio. The cakes were dense and delicious, like my favorite banana bread. The rich, salty peanut butter butter filling was smooth and decadent.
Best served with a tall glass of cold milk.
Indulgence never tasted so good.




I have a whoopie pie pan that has yet to be used. That should change soon!
OMG, amazing!
the middle layer
3/4 c each of butter, sugar, and PB….I would just like to eat that for every meal for the rest of my life!
Those are so cute – honestly, those would be dangerous around me!!
I would totally eat that whole plate of these right now. My weakness lies in peanut butter!
Oh wow, those look amazing! I saw some whoopie pie pans at World Market recently. I’m so going back to buy them and try this recipe!!
What an awesome combo. Banana + peanut butter = healthy, right?!
I need one of those right now!! They look so amazing
Now that’s the amount of frosting I can get behind.
You can never go wrong with extra frosting!
Best introduction ever. Who doesn’t have a designated “muffin top” pair of pants!?
Ooooh these sound delicious! Love the flavors that you used…mmmmm!
Oh stop it, I just got fatter LOOKING at these. YUM.
Using muffin top pans to keep whoopie pies in control is such a great idea – as are these flavors. Nice job!
Yes please! I’ll take a batch! : )
That looks like the most dangerous plate ever. I’m not sure I could be trusted with peanut butter frosting.
These look so delicious! I love the banana and peanut butter combo. Can’t go wrong with that. Love TJ Maxx too – always find great deals there!
These look redunculously good. A must make!
You’ve batted 100 with these whoopies! With spring upon us and baseball soon to follow, these will be a hit after a game at the ball park!
Oh my do those whoopie pies look sooo insanely good. I’d gladly eat a dozen of them for you right now.
@Lindsey @ Gingerbread Bagels, They didn’t last long!
@Cakewalker, Or any time, really.
@Natalia – a side of simple, Oops- I think you read it wrong, but this is even funnier… muffin top PANS! Like the baking pans… but I got a good laugh. Those too!
@Emily @ A Cambridge Story, Precisely!
I think I just died laughing. TOTALLY read that wrong. Whelp, I guess the news is out about my pants! I guess I was just so excited
Peanut butter and banana whoopie pies are a great idea!
