Whoopie Pie Cake

cake

This Easy Whoopie Pie Cake is an instant favorite..filled with delicious Marshmallow Buttercream!

Sometimes simple is better.

Actually most times, yes?

 

So this post is gonna be simple.

 

This Whoopie Pie Cake was sort of accidental.  Obviously not accidental in intention, but accidental in execution.

See, I was going to make this a super fancy, stack-o-whoopie pies piled up to make a giant gorgeous deconstructed type cake.

 

Unfortunately, ain’t nobody got time for that.

Meaning me.  I ain’t got time for that.

 

So I took the easy route.

It might not be as visually appealing as a giant stack of whoopie pies…I mean not much would…but it is incredibly tasty.

And also, you can actually slice it without holding your breath.

Which is kind of important, because I can only hold my breath for like 7 seconds before I’m certain I will faint.

Whoopie Pie Cake.

Simple. Delicious. Make it.

Whoopie Pie Cake | Cookies and CupsJust start with a chocolate cake mix.

Grease 2, 9×13 pans with butter and dust with cocoa powder.

Split the batter evenly between the 2 pans.
(Obviously if you don’t have 2 pans, just bake one at a time.)

This is actually an optional step, but not really 😉

Just heat up some heavy cream to almost boiling and then add in your chocolate chips, stirring until smooth.

I work at a restaurant and always bring the staff treats on the weekends. Guess what they are getting this weekend. Think I’ll make in the round pans to look like a giant whoopie pie. Thanks for the idea.

MMMM whoopie pie cake! Sometimes when you don’t have time to make a fancy dessert, you end up liking your more simple version anyway!

I’m having one of those days….no, scratch that. I’m having one of those WEEKS when a decadent whoopie pie cake like this could really make the sun shine a little brighter… Soooooo…wanna fly one across country for me? Pretty please? 😉 Seriously, this is just crazy awesome, Shelly.

This looks delicious!! Do you use a cake mix with or without pudding in it?

Joanne
Guest

I do love me some crazy layer cakes…but sometimes I also just want two chocolate layers with some vanilla sandwiched in between. This cake is perfecto for that!

So, I’ve been eating marshmallow fluff out of the jar. It’s a problem. I’ve got to stop. The civilized thing to do is make a cake and eat it!

this could be the best thing I ever ate — made it in two 9″ pans, for Memorial Day picnic, and it disappeared so fast it left a cloud of dust (crumbs?) Thanks for a great recipe, it’s a keeper!

Your whoopie cake looks awesome! What cake mix brand did you use? I want to bake this cake this weekend, just want to make sure I buy the same cake mix you used. Thanks!

Babs

I am making your whoopie pie cake tomorrow for my beau’s birthday and I have every bit of faith it will be fantastic!
He’s from Maine where whoopie pies are as necessary as breathing and when I found your recipe I jumped for joy.
Thanx so much!!!!!

Jen

Help! I so want this to be amazing, but I made it today and my “fluff” didn’t really fluff. Your picture looks white and fluffy and marshmallow-y. But mine came out sort of yellow (the butter) and too runny. What could I have done wrong and how do I fix it when I try again? Thanks!
