S’mores Cake. Just those two words are enough to make my heart flutter. Layers of rich chocolate, crunchy graham cracker, and creamy marshmallow… all in a cake? Yes yes yes.
I have been compensated by The Kroger Co. for this post, but the opinions are mine and mine alone. Keep reading for the S’mores Cake recipe!
I learned how to make roll cake the other week, so I decided to try another one and combine all three classic S’mores components into a S’mores Cake Roll!
Once you’ve got the hang of making a roll cake (step-by-step tips here!), making a S’mores Cake is just as easy. The key is ensuring that you have graham crackers, chocolate, and marshmallows on hand. For this S’mores Cake, I went to my local Kroger store (they’re called Ralphs here in Southern California) and picked up Honey Maid Graham Crackers, Kraft’s Jet-Puffed Marshmallows, and some Hershey chocolate bars. Could a S’mores recipe get any more classic? I don’t think so.
How to Make a S’mores Cake
To bake this S’mores Cake recipe, I had figure out how to create a chocolate sponge (i.e. the cake bit) that rolled easily. Because, while I have a chocolate cupcake recipe that’s been my go to for years — and which I really should share with you! — it rises a lot and, thus, isn’t suitable for making a chocolate roll cake. So, I researched, compared recipes, worked out all the ratios in a spreadsheet (this is totally a normal method, right?) and then was left with a bit of a quandary. Do I use baking powder or no?
Baking powder is excellent at making baked goods rise. And almost every recipe I found for a chocolate roll cake called for baking powder. This didn’t seem like a good idea. But, hey, ok, baking powder it is. Since my friend Ashley and I decided to film this, I made a few tester S’mores Cakes in the early morning.
The video is coming soon, but in the meantime, check out her YouTube channel and her recipe for how to make Bulletproof Coffee! —
The chocolate cake rolls looked great. They rolled beautifully. And then. And then hours later, when she arrived for filming, they were a hot mess. They stuck to the paper. They crumbled into bits. They basically threw a giant tantrum and refused to participate in any of the fun. I knew the baking powder had to go, but unfortunately, there wasn’t time to make another tester… so we had to do it live!
The S’mores Cake without baking powder was thinner, didn’t crack, and rolled without fuss. I filled it with a chocolate ganache, marshmallow frosting (I used marshmallow fluff, but a thinner version of this homemade Marshmallow Frosting would work too!), rolled up the chocolate roll cake, then topped it with more chocolate ganache, graham crackers, marshmallows, and chocolate.
Because I’m such a marshmallow fan, I will probably double the amount of marshmallow frosting when I make this S’mores Cake again – and maybe sprinkle graham crackers on top of the frosting, which would add a nice crunchiness to each bite. Actually, I think that’s one of the best things about this S’mores Cake recipe: you can totally customize it to your liking!
