This S’more cake is a chocolate cake that is filled with marshmallow creme and then frosted with chocolate buttercream frosting. Then crushed graham crackers are pressed against the outsides and the top has a pour of chocolate ganache with toasted marshmallow and Hershey’s chocolate bars. It’s decadent and totally delicious!
This cake is the perfect s’mores and chocolate lovers cake. It tastes like a brownie, chocolate cake and a s’more combined. It’s indulgent and sure to make the marshmallow and chocolate lovers happy campers – pun intended – just without the campfire and smokey smell.
This cake is a little slippery because of the marshmallow creme between the layers so you can use a wood dowel down the middle if you are having problems with it sliding.

Instructions for chocolate buttercream:
- Blend all ingredients in a large bowl with an electric mixer with a whisk attachment. It can also be blended by hand with a whisk.
Instructions for the S’more cake:

- Blend together the butter and sugar together until smooth.
- Add cocoa powder, vanilla and eggs.
- In another bowl, add the flour, salt and baking powder and sift together.
- Add the flour mixture to the butter mixture, followed by the milk mixture.
- Stir together until batter is smooth.
- Grease and flour your pan and divide batter between the different pans. Don’t fill more than 1/2 full.
