Your Supply List:

- An extra egg.
- Cocoa powder.
- Marshmallow fluff.
- Powdered sugar.
- Butter.
- Chocolate chips.
- Butter.
- Milk.
How to Make Your Whoopie Pie Cake + a Few Notes:
- Mix the ingredients on your cake mix box, plus, an extra egg.
- Spread 1/2 of the batter into a 9 x 13 pan. Then, spread the remaining batter into a second 9 x 13 pan.
- BAKE!
- Let the cakes cool for 10-15 minutes, then, remove them from their pans. Then, let them cool completely before adding the filling.
- Make your filling 👉 make sure your butter is softened before mixing!
- Spread filling evenly on top of one cake. This may be messy and have some overflow. Placing the cake on a flat rimmed baking sheets (lined with parchment paper) will make this process easier.
- Carefully, place the second cake on top of the filling. Take your time with this. You can see in one of my pictures, my cake broke a bit. It’s not a huge deal, the frosting will cover any blemishes. But, you don’t want a total mess, so, take your time with it.
- Finally, make the frosting and spread on top of the cake. Let the cake sit for 30 minutes to an hour for the frosting to set. To speed up this process, place the cake in the refrigerator for approx 15 minutes.
- This cake is ah-ma-zing! But, it’s sweet, start with small portions. 😉
