Ingredient Notes:
- If you’re not into pumpkin spice, you can leave it out of the crust and the mousse. The tart will still taste delicious.
- Be sure to use bar chocolate and not chocolate morsels. Morsels have stabilizers in them that prevent them from melting properly.
- Make sure to have the individual pieces of crystallized ginger separated out, rather than in one big clump. That way you can easily fold them in.
How to make it:
See full ingredients & instructions in the recipe card below!
Make the crust:
This recipe starts with the crust and just like any graham cracker crust dough, this one is too brittle to roll out and transfer into the tart pan, instead you need to press it in with your fingers.
Step 1. In a bowl, whisk together both flours, wheat germ, salt and pumpkin spice. Set aside.
In a separate bowl, whip together butter, sugar and honey, then whip in the dry ingredients.
Step 2. Transfer the dough into a 9-inch greased tart pan with removable bottom. Note: It will look like a whole lot of dough at first but once you press it in, it will fill a 9-inch tart pan perfectly.
RECIPE TIP: I recommend using a fluted, non-stick tart pan with removable bottom for this s’mores tart because that will make it very easy to get the tart out of the pan.
Step 3. Start pressing the dough into the pan using the bottom of a cup measure.
Step 4. Finish pressing the crust into the pan using your fingers, then chill in the fridge. Bake the crust in a 350-degree oven until it turns golden-brown. Let cool completely.
Make the filling:
Step 5. Add finely chopped bittersweet chocolate and pumpkin spice to a small bowl. Bring heavy cream to a boil, pour it over the chocolate and let the mix sit for a minute.
Step 6. Whisk the mix into a smooth ganache and set aside.
Step 7. Whip heavy cream and sugar to stiff peaks.
Step 8. Fold the chocolate ganache into the whipped cream.
Step 9. Spoon the mousse into the tart shell and spread out with an offset spatula.
Step 10. Chill the tart in the fridge for 1 ½ hours.
Make the topping:*
*RECIPE NOTE: Make the meringue topping right before serving the tart. Once the topping is on, it cannot sit around for very long.
Step 11. When you’re ready to make the meringue topping, whip egg whites until they start to foam, then slowly whip in granulated sugar, followed by sifted powdered sugar.
Step 12. Fold finely chopped crystallized ginger into the meringue, then dollop it onto the tart.
Step 13. Finish the tart with a quick blow of the kitchen torch and serve immediately after that.
How to serve it:
Serve the tart immediately after finishing the meringue topping.
How to make the tart ahead:
You can freeze the mousse tart (before topping it with the meringue) for at least a week, if you want to make it ahead. Let the tart thaw on the kitchen counter for about 1 hour, then top it with the meringue and serve.
Can I make this tart without the meringue topping?
Yes! This tart is quite delicious even without the meringue topping. If you want to make it without the topping, I recommend serving it with whipped cream and/or cherry or raspberry preserves.

OMG, this looks incredible. Growing up as a girl scout, we always made s’mores on our campouts. I am vegan and this recipe can easily be veganized. Thanks for sharing.

Love this stunning tart, Nicole, I am mesmerised by that cloud of meringue! So beautifully captured as always! Thank you for sharing the homemade graham cracker recipe, as we can’t get them here in the UK. xx
Nicole B.
Thank you so much for your kind words, Louise! I had actually never thought about graham crackers not being available elsewhere, come to think of it, I have no clue where they originated (or where their name comes from). :)

These flavours sound completely novel for S’mores. Ginger and chocolate is one of my favourite combinations. That and the fact that it’s in S’more form, of course. Beautiful as always, Nicole.
