This S’mores cake packs all the flavors of a classic s’more into a delicious cake. It starts with a graham cracker crust, followed by a layer of chocolate cake. Then it’s filled with vanilla bean marshmallow and topped with a rich chocolate ganache and extra marshmallows.


Can I use milk chocolate instead of dark chocolate for the ganache?

How long should the cake cool before applying the marshmallow cream?
Let the cake cool completely before adding the marshmallow cream to get the best texture.

Can I use a different flavor extract in the marshmallow cream?
Absolutely! Feel free to try different extracts for a unique flavor.

Can I make the cake in a different size or shape?
While this recipe is designed for 6″ cake pans, you can use 8″ cake pans for two layers. Just adjust the baking time accordingly.
