If you have ever stood around a campfire thinking someone needs to make this into a real dessert, this s’mores tart is exactly that. Every single element of a classic s’more elevated into a stunning tart that looks like it belongs in a bakery window and tastes even better than it looks. Buttery graham cracker crust, silky dark and milk chocolate ganache, and a thick layer of toasted marshmallow fluff torched right on top until it is perfectly golden and caramelized. This is the dessert you bring to a dinner party and never tell anyone how simple it actually was to make.
The chocolate ganache is where this tart really sets itself apart from every other s’mores dessert out there. A combination of two thirds dark chocolate and one third milk chocolate gives you a ganache that is rich and deeply chocolatey without being bitter, with just enough sweetness from the milk chocolate to make every bite completely balanced. It sets up into this perfectly smooth, sliceable layer that holds its shape beautifully and has the most incredible glossy finish before the marshmallow goes on top. The ratio matters here and it is worth measuring it out exactly to get that perfect chocolate depth.
The marshmallow topping is the most fun part and also the most impressive looking. Whether you use store bought marshmallow fluff or make your own, spread it generously over the completely set ganache in big swooping peaks and then take your kitchen torch to it. Work in slow circular motions and get right up close so you get that deep golden color with the slightly charred edges that taste exactly like a real campfire marshmallow. The torch moment is genuinely one of the most satisfying things in all of baking and the result looks absolutely stunning every single time. Click HERE for the torch I use!
This s’mores tart works for any occasion that needs a showstopper dessert. A summer dinner party, a birthday celebration, a holiday gathering, or honestly just a weekend when you want to make something that feels really special. It comes together in about an hour including chill time and slices beautifully into clean pieces that look gorgeous on a plate. The campfire in tart form. Make it once and it becomes the dessert everyone requests.

- Pour cream over chocolate and let it sit for 2 minutes.
- Using a whisk, combine chocolate and cream until smooth.
- Add butter and stir until butter is fully melted and incorporated.
- Pour ganache into cooled crust and refrigerate until set (usually a few hours)
For the Marshmallow Fluff:
- In a sauce pan, combine water, sugar and corn syrup and stir until combined. Do not stir beyond this point.

Top and Finish:
- Top tart with heaping blobs of marshmallow fluffs and use the back of the spoon to create big swirls. The more definition and divets you add, the more texture you’ll have when you toast!
- Using a kitchen torch, toast the top generously, charring some parts and leaving some white and golden brown.
- Slice with a hot clean kitchen knife and enjoy!!
