This improvisation on the epic whoopie pie recipe, which is traditionally halfway between a sandwich cookie and cake, takes the dessert all the way to cake land by producing a slab cake covered in ganache. As easy as this cake recipe is to make, it is also stunning to look at with spongy cake layers and fluffy white icing between two layers. Also, the fact that this whoopie pie cake recipe is a slab cake means it is an excellent choice for serving a crowd and would be the type of dessert any kid would enjoy if you are looking for kids birthday cake ideas. If you want a chocolate cake to serve at your next potluck or just want a sweet treat through the week, this easy cake recipe is for you.

The more usual cake baking involves deep round spring form cake pans and sometimes rectangular, but unfortunately, not everyone has the cake pan to suit all their baking needs. In the case of this chocolate cake recipe, you only require 9x13 inch cake pans, which are an incredibly versatile item for the kitchen and a pan size that most people have because they are perfect for making squares or brownies. This rectangular pan allows you to get two large cake layers to sandwich the marshmallow fluff icing recipe between. The added bonus is that you don’t have to slice horizontally through the layers either like you would with other cake recipes and could be a challenge with such a large cake. Although this recipe specifies to grease and dust the cake pans with cocoa powder, if your pans are a little older, they may have lost some of their non-stick nature and simply greasing may not be enough. Rather than fussing with cakes that are stuck to their pans, consider lining the 9x13 inch pans with parchment paper, because this will make removing the cakes a foolproof affair. Otherwise, if your pans are still trusty vessels for cake baking, you can follow the grease and dust method in this cake recipe.

As with any whoopie pie recipe, a mandatory ingredient is the frosting that gets sandwiched in the center. Sometimes this can be a simple white buttercream and other times it might be a marshmallow cream. This cake uses a marshmallow cream involving just three ingredients for a simple, decadent, and fluffy icing to place between cake layers. A key ingredient would be the marshmallow fluff, which you can purchase in most grocery stores and gives the frosting its signature light and airy texture. The whoopie pie has become such a notable treat in the U.S. that it is no wonder that Shelly, the author of Cookies & Cups recipe blog, came up with her unique version. There is much contention over the origins of this dessert recipe with people attributing it to New England, Pennsylvania, and Maine, but one thing is for sure, everyone loves these sandwich cookie cakes. Thank you to Shelly for sharing her whoopie pie cake recipe with us.
