You all know that I have an itsy bitsy obsession with marshmallow fluff, and this cake is pretty much the cake of my dreams. Anything s’mores flavored I am ALL over it. S’mores macarons, s’mores brownies, s’mores icebox cake…I mean I could eat this flavor combo for the rest of my life. So it probably come as no surprise that we just had to make a S’mores cake.
DUH. I honestly can’t believe it took us this long to take all those flavors of an ooey gooey s’more into a layer cake.
What’s your favorite party of a s’more? The golden marshmallow? The melty chocolate? The crunchy graham? Well I love them ALL.
Best part about this cake? All three get to shine through in their own individual layer.
What is a s’mores cake:
S’mores cake takes the three key components of any good s’more and makes each one into a decadent layer. In case you live under a rock, a s’more is made from toasted marshmallows, chocolate, and two graham crackers sandwiched together. It’s easily one of my favorite flavors combos. You’ll make three separate components and then assemble them.
And I’m going to break it all down for you.
- Chocolate Cake: We used our favorite chocolate cake recipe to make the fudgiest, most chocolatey cake we’ve ever had.
- Graham Cracker Crumble: You know that buttery goodness traditionally found as the base of a graham cracker? We adapted that into a crumble to sprinkle in between each layer of cake (PSA it is to die for).
- Marshmallow Buttercream: Made with marshmallow fluff stirred right into the frosting, this ultra fluffy frosting tastes exactly like a marshmallow
And damn IT. IS. GOOD.
How to assemble s’mores layer cake:
This recipe will make a 2 layer 8 inch cake or a 3 layer 6 inch cake like we made here!
Simply place your first layer on a cake stand and frost the top of it with marshmallow buttercream. Sprinkle with half of the graham cracker crumble. Next, place another layer on top and repeat the process.
Place the last cake layer on top and frost the top and sides of the cake. We topped ours with chocolate ganache and toasted marshmallows but you could do anything!
The only thing that could possibly make this s’mores layer cake better would be serving it with a scoop of Ben and Jerry’s S’mores ice cream.
I thought it was discontinued but a quick google search shows that it’s still in stores and my grocery store stopped selling it. So basically it’s just discontinued for me.
So if you see Ben or Jerry around, please let them know we need them to bring their S’mores ice cream back to my grocery store so that we can eat it with this cake.
That is all.

Looks amazing! How does the graham cracker layer not get soggy in the middle?
Hi Sandra! It will get a little bit soggy, but the honey helps it to clump together and protect it from soaking up too much moisture!
My whole family tore up this cake lol! It was soooooo good. I used the regular 100% cocoa powder instead of the dark so it was a little sweeter than the first time I made it. Thank you!

I recommend tripling the frosting recipe but otherwise the cake is delicious! This is my go-to chocolate cake recipe and it’s always popular. I also used 2 8-inch pans so I could get 4 layers and added a little extra fluff to the frosting. It was super delicious!

This Cake is outrageously delicious! I made it for our 10 year anniversary. Just be warned, double or triple the frosting if you plan to frost your layer cake normally rather than in this (adorable) half-dressed style. The frosting is delicious so I wanted a thick layer all over the cake. Thank you for this gem!! I followed the directions exactly and it was PERFECT.

My son asked for a S’More cake for his birthday and we found this. It was fantastic. We only did two layers and had to more than double the frosting (definitely recommend more than the recipe calls for). I also found the grahm cracker layer to be way to sweet. I look forward to trying it again without the added honey to this layer to balance out some of the sweetness. Amazing chocolate cake recipe. I used a simple chocolate syrup for the topping and it worked great. Kept well for left overs too.
