Easy Double-Layer Chocolate Cake Recipe

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.

How to Make a Whoopie Pie Cake With Cake Mix:

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.

If made in 2 9x9s, how long is the cake baked for?
I’ve made the 13×9 multiple times…..just saying, I eat half the filling before it makes it to the cake!

I brought this to our Bible study group and it was a HUGE hit. Everyone raved about it! I added about 3/4 c mini chocolate chips to the cake batter, and I added some extra powdered sugar to the filling. I thought the filling tasted too much like butter before I added the extra powdered sugar. In hindsight, I wonder if a little vanilla might have been good in the filling. When it was all put together, the taste was amazing!

you said this cake does not have eggs, but the recipe does call for one egg. Is there a way to make it without the egg?

This recipe and picture made by mouth water by just looking and reading the recipe. It has to be delicious. There is a recipe called: Death by Chocolate. I think this could be the alternate name for this recipe. Thank you from this Chocoholic.

I made this cake for my family dinner and they just loved it. It really does taste like a Hostess cupcake, only better. It is delicious and rich tasting. Now they are asking me to make it again. Thanks for the recipe.

This looks great! Any tips to get the cake out of the pan neatly? It looks like you flipped them upside down? Thanks!!

This cake is listed as egg free, then tells you to add an extra egg beyond what’s called for on the box of cake mix. Very disappointing……

We have a 14 year old border collie and wanted to celebrate her birthday. My niece suggested we choose a dessert that was black and white to go along with our Julie Dog- your whoppie cake was perfect! It was easy and delicious! The whole family loved it! Thanks so much!

I don’t know how to bake and no one else in my household does, so I will just sit in the corner and cry. Don’t pay any attention to me. Thanks for the pictures and all of the posts. That cake, a gallon of vanilla ice cream and hot, black coffee would be the perfect day before death for me. Thanks.

This looks amazing!! Can’t wait to make it this weekend. One question, would the filling still work if I only use 1/2 cup butter? Don’t get me wrong, it would be heavenly for sure…but I’m not sure my heart can handle that much butter!! Ha ha!!

Looks delicious & easy. Perfect combination. I’m so making this. Thank you.

Carolyn,

Marshmallow fluff is also called marshmallow creme in some places. It is a marshmallow flavored creamy stuff usually found in the baking section.

Deb

i got half and half instead of heavy cream, what can I do to to substitute, I do not want to go to store. Cake in the oven

Sarah Ü

is there a reason to bake two separate cakes? Could you bake one 9×13 and slice it in half? I realize it might be a little crumby that way, but any other reason? Thanks!!

carolyn
