Hostess Cup ‘Sheet’ Cake
Do you remember when Hostess went bankrupt and no one could get their tasty, completely unhealthy pastries? I.WAS.DEVASTATED! Hostess Cupcakes are my absolute favorite quick pastry. I knew I had to find those flavors in a homemade DIY edition…thus the Hostess Cup ‘Sheet’ Cake was born.
This was out of laziness as well as desperation. While it is fun to eat a cupcake, I wasn’t about to make a bunch of cupcakes that required filling. I just cannot make those types of commitments to food. I knew I could easily add the same flavors to a sheet cake.
Devil’s food cake, marshmallow flavored filling, chocolate ganache on top…these were my main priorities. I was WAY less concerned with the presentation of it. While I wanted the end result to look tasty and a little bit of whimsy that brought the consumer back to the Hostess days, I also didn’t want to spend hours upon hours waiting to be able to shove the tastiness into my drooling mouth.

Instructions
Chocolate Cake
- Preheat oven to 400°F. Grease and flour a 10 X 15 inch cookie sheet with sides. Set aside. In a large bowl, sift together flour and sugar. Set aside. In a medium saucepan, mix together butter, shortening, cocoa and water and bring to a boil. Pour over flour and sugar mixture. Mix well. Add buttermilk, soda, cinnamon, vanilla, eggs, and salt; mix well. Pour into cookie sheet and bake for 20 minutes or until a toothpick inserted comes out clean. Allow cooling completely before adding on the marshmallow frosting.
Marshmallow Frosting
- In a bowl add in the marshmallow fluff, 3 cups of the powdered sugar, the marshmallow flavoring, and beat with an electric mixer. Add in another cup of the powdered sugar, beat again. Add in 1 Tbsp of whole milk, beat. Add in the last cup of powdered sugar and beat until a thick consistency. You may need to add in 1-2 more Tbsp of whole milk. Don't add too much though because if it is too runny it will run right off of the top of the cake. Place the cake in the refrigerator for 30 minutes to allow the marshmallow frosting to harden slighly.
Chocolate Ganache
- In a microwave bowl, pour in the semi-sweet chocolate chips and the whole milk. Microwave in 15 second increments, stiring in between each, until the consisitency is nice a smooth. Add in the salt and stir more. Pour over the marshmallw frosting and place back into the refrigerator for at least 4 hours.
White Icing
- In a bowl add in the powdered sugar and the cold water 1 tsp at a time, mix until a slightly runny consistency. Pour into a frosting bag or a Ziploc bag. Cut the very tip off, but only very slightly. You do not want the hole to be large. You are going to do detailed piping work. Begin swirling the icing in rows over the chocolate ganache. Place back into the refrigerator for another 15 minutes. Serve immediately, or keep in refrigerator up to a week.
Nutrition
The thing that really makes this is the marshmallow frosting. Adding the extra marshmallow flavoring isn’t necessary, but, in my opinion, the marshmallow flavor from the marshmallow cream just isn’t enough to take it to tasty status.
This marshmallow oil is some POTENT stuff. You need very little to go a LONG way! ALSO…the marshmallow frosting is the perfect addition for any cupcake or cake recipe.
Do you have a favorite Hostess treat? Were you as upset as I was when they temporarily left the shelves? Hope y’all are having an amazing week. Stay safe and happy.
