S’more Cake

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.

What you need to make S’more cake:

Makes a 3 tier 8 or 9 inch cake or a 4 layers of 6 inch cake.

  • 1 tablespoon vanilla extract
  • 2 tablespoons cocoa powder
  • 1/2 teaspoon salt
  • 1/3 – 1/2 cup milk – Depending on the thickness desired, I frost my cakes with 1/2 cup thickness but my sandwich cookies with 1/3 cup thickness.

Instructions for chocolate buttercream:

  1. 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.

  6. Add the flour mixture to the butter mixture, followed by the milk mixture.
  7. Stir together until batter is smooth.
  8. Grease and flour your pan and divide batter between the different pans. Don’t fill more than 1/2 full.
  9. Bake according to bake times below:
  10. Cool or freeze cakes.
  11. If you want thinner layers like I did on my cake you can slice the cakes in half.

  18. Pour over chocolate chips and cover bowl. Let sit for 3 minutes or until chocolate is melted. Stir until chocolate is shiny and all melted. If it doesn’t melt completely, microwave for 15 second intervals, stirring after each time until all chocolate is melted.
  19. Cool until semi-set so it isn’t super runny, then pour slightly cooled chocolate ganache over the top of cake and let it drip down the sides slightly.
  20. Toast the marshmallows under a broiler for 1-2 minutes (watch carefully).
