Peanut Butter Banana Whoopie Pies

September 12, 2024 By Gretchen

Jump to Recipe Jump to Video Print Recipe

Peanut Butter Banana Whoopie Pies are going to make your hips gyrate like the King himself!

Also known as the Fat Elvis, these delicate little banana cakes are filled with creamy peanut butter buttercream, fresh banana slices and drenched with chocolate ganache!

Peanut Butter Banana Whoopie Pies

This fast dessert idea is a great way to use up all those frozen bananas that are taking up residence in your freezer!

You don’t even have to pull out the mixer to make the whoopie pie recipe since it’s a one bowl mix!

 

 

The ganache icing is optional but really transforms these little hand held cakes into an elegant plated dessert!

Just be sure that if you are using the fresh bananas as added filling to these little cakes, that you do so ala minute so they don’t turn brown!

Notes for Success:

If you are not up for making a recipe of buttercream for the filling you can follow the peanut butter recipe below but just leave out the buttercream addition.
The filling will be more like a Reese’s Peanut Butter Cup which of course is not a bad thing!

Graham cracker crumbs in the peanut butter filling is an optional ingredient, I like it because it tastes more like a true Reese’s Peanut Butter Cup filling but you can leave it out with no changes to the recipe
And the buttercream addition is also an optional ingredient, but will make the filling creamier and lighter

I am using a 1½ ounce cookie scoop for this recipe

    Hey Gretchen,

    Was worried that you had left your fat pants in Florida, glad to see you have put that fear to rest. Bananas in anything makes it good.
