Easy Chocolate S’mores Cake
This indulgent chocolate s’mores cake is the definition of pure decadence. It starts off with a dense cookie butter infused chocolate cake. Filled with marshmallow fluff, covered in delicious chocolate frosting, covered in chocolate sauce and topped with toasted marshmallows!
My favourite thing about this cake is how dense and fudgy the cake is. And it’s so moist! I also can’t say no to those toasty marshmallows. Even long after they’ve been toasted, they may not be soft and gooey anymore, but the toasty caramelised flavour is still there!
What does this cake taste like?
Easy chocolate s’mores cake is sweet, dense intense chocolate with toasty marshmallows! It’s funny, I was walking around the house after I toasted the marshmallows and the smell wouldn’t leave me so I may have picked off a few after I finished the cake.
What you need for the RECIPE
This cake has a fair few ingredients but it’s easy to put together and the payoff is huge! A dense, yet light and moist cake with an intense chocolate flavour!
All-Purpose flour – this is just regular plain flour.
Cocoa powder – use good quality dark cocoa powder. The unsweetened kind.
Baking powder – this helps the cake rise
Bicarb soda – this also a raising agent that helps the cake rise and is often used with acidic ingredients like cocoa powder or lemon.
Salt – adds flavour to the recipe. I use the pink Himalayan salt only so that you guys can see it more easily on screen, but regular white fine salt is fine to use.
Malt powder – I actually couldn’t find malt powder so I ended up using milo which is a chocolate malt powder. So either is fine.
Brown sugar – this is a much sweeter way to sweeten this cake and bring out a deep rich chocolate flavour.
Buttermilk – buttermilk is often used to make cakes more moist. If you don’t access to it you can make it yourself using 1 tbsp vinegar or lemon juice per 1 cup of milk and let it sit for 5 minutes before using.
Vegetable oil – you can use sunflower oil in its place.
Eggs – I used large, room temperature eggs.
Cookie butter – this stuff is so yum! I happened to have a jar of the crunchy version of this one.
Vanilla extract – I used pure vanilla extract for this.
Boiling water – this will help make the batter really smooth and bring it to room temperature which results in a really moist cake,
Mini marshmallows – These can be found in the baking section or powdered hot drink section of your supermarket.
The frosting in this recipe is a silky indulgent chocolate frosting!
Butter – I used softened butter for this.
Powdered sugar – you want to use powdered sugar for this so you end up with a smooth buttercream.
Cocoa powder – Make sure you use unsweetened cocoa powder. This helps bring a really deep and rich chocolate flavour to the frosting.
Dark chocolate – I melted the chocolate in the microwave for 30 seconds at a time, stiring each time until it was smooth. It’s important you let your chocolate cool slightly before adding to the frosting otherwise it will cause your frosting to melt.
Marshmallow fluff – Optional. You could just use chocolate frosting if you like, but tea with the theme! This elevates the cake.
The ganache that goes on top of this cake is smooth and it’s so easy to make!
Dark chocolate – make sure you’re using dark chocolate and that it’s cooking chocolate for best results here.
Heavy cream – at least 30% fat content. This is the cream you use for whipping.
We’re topping this cake with toasted marshmallows and graham crackers. See the notes below on different ways to toast the marshmallows.
Graham crackers – if you can’t find graham crackers, anything close to it is fine. You could easily get away with using digestives.
Giant marshmallows – If you can find these, bonus! I found these at Woolworths in Australia. But you can use regular sized marshmallows and it’d look just as good!

Tips for making easy chocolate s’mores cake RECIPE
- When slicing the cake, if you want those really nice clean cuts, clean the knife each time you slice!
- When toasting the marshmallows, if you’re using a kitchen torch to toast the marshmallows, just take care of any marshmallows that may catch fire. It can happen easily. Just keep an eye out and blow out the flame otherwise your marshmallow will turn to black charcoal.
