Whoopie Pie Cake

This is by far one of the best cakes, maybe even one of the best recipes overall, that I have ever made. I made this for my birthday party on Friday and everyone loved it. Someone even said it was the best cake they'd ever had. It is extremely decadent, so a small slice will do the trick. I highly recommend making this one when you get the chance! The original recipe is from Cookies and Cups, and I've added a few of my own notes as well:

Ingredients:

• Cake
• 1 box Chocolate cake mix (prepared per package directions) + 1 extra egg
• *cocoa powder for dusting the pan
Filling
• 1 cup butter, room temperature
• 2 cups Marshmallow Fluff
• 3 cups powdered sugar
Ganache
• 1/2 cup heavy cream
• 1 cup semisweet chocolate chips

How to Make

Cake
1. Preheat oven to 350°
2. Grease 2 9x13 sized pans with butter and dust with cocoa powder, set aside.
3. Prepare cake according to package directions, but add in an extra egg to the mix.
4. Split the batter evenly between the 2 pans and bake for 15-20 minutes until a toothpick comes out clean.
5. Allow cakes to cool completely.
Filling
6. In stand mixer beat butter and Fluff together until smooth.
7. Turn mixer to low and slowly add in powdered sugar. Turning mixer back up, continue mixing for 30-60 seconds until smooth.
8. Spread the filling on top of one of the cakes. Top the filling with the other cake.
Ganache
9. In small saucepan bring the heavy cream to almost a boil. Remove from heat and stir in chocolate chips. Allow to cool for 10 minutes and then pour over top of cake.

My Notes:

- I don't usually use an electric mixer, but it is actually a really good idea to use it for the filling, because that marshmallow fluff can be thick

- A regular sized jar of marshmallow fluff from Jet-Puf is just about 2 cups. Perfect!

- I used two 9x9 pans to make a round cake rather than a rectangular one. The bake time was about 30 minutes instead of 15-20
