How to make a s’mores mousse tart:

You start 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 but that’s quite easy to do.

Whisk 3/4 cup all-purpose flour1/2 cup whole-wheat flour1/4 cup wheat germ1/4 teaspoon salt and 1/2 teaspoon pumpkin spice together in a bowl.

Set the flour mix aside and in a separate bowl, whip together 8 tablespoons softened, unsalted butter1/3 cup light-brown sugar and 1 tablespoon honey.

Beat the flour mix into the butter and continue to beat until the dough becomes crumbly.

Transfer the dough to a 9-inch greased tart pan with removable bottom.

RECIPE TIP: I recommend using a fluted, non-stick tart pan with removable bottom for this tart because that will make it very easy to get the tart out of the pan.

Start pressing the dough into the pan using the bottom of a cup measure.

Finish pressing the crust into the pan using your fingers, then chill the tart pan in the fridge for 20 minutes. Heat the oven to 350 degrees F. and bake the crust until it turns golden-brown (8 to 12 minutes). Let the crust cool completely.

The chocolate mousse filling is easily made with melted bittersweet chocolate and heavy cream and I added pumpkin spice here as well but if you don’t like that, you can just leave it out.

Chop up 5 ounces bittersweet chocolate, put them in a small bowl, then bring 3/4 cup heavy cream to a boil, pour it over the chocolate and let the mix sit for a minute.

Whisk the mix into a smooth ganache and set aside.

Whip 4 egg whites until they start to foam, then slowly whip in 1/4 cup granulated sugar, followed by 3/4 cup powdered sugar.

Fold 1/2 cup finely chopped crystallized ginger into the meringue, then dollop it onto the tart.

RECIPE TIP: You want to 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.

Finish the tart with a quick blow of the kitchen torch and you’re all set.

Ingredients:

For the graham cracker crust:

  • 3/4 cup all-purpose flour
  • 1/2 cup whole-wheat flour
  • 1/4 cup wheat germ
  • 1/4 teaspoon salt
  • 1/2 teaspoon pumpkin spice
  • 8 tablespoons unsalted butter, softened
  • 1/3 cup light-brown sugar
  • 1 tablespoon honey

For the chocolate filling:

  • 5 ounces bittersweet chocolate, finely chopped*
  • 1/2 teaspoon pumpkin spice
  • 3/4 cup heavy cream
  • 1 cup heavy cream
  • 1 tablespoon granulated sugar

For the meringue topping:

  • 4 egg whites
  • 1/4 cup granulated sugar
  • 3/4 cup powdered sugar, sifted
  • 1/2 cup finely chopped crystallized ginger (make sure you have the individual pieces more or less separated and not in one large clump to make it easier to fold them into the meringue)

Instructions:

For the graham cracker crust:

  • Whisk the flours, wheat germ, salt and pumpkin spice together in a bowl.
  • Beat butter, sugar and honey for a few minutes until fluffy.
  • Beat in the flour mix.
  • Transfer the dough into a 9-inch greased tart pan. (It will look like a lot at first but it will compress greatly when you start to press it in).
  • Press the dough into the tart pan, using a cup measure and then your fingers. 
  • Place the pan in the fridge for 20 minutes.
  • Heat the oven to 350 degrees F.
  • Bake the tart crust until golden-brown (8–12 minutes).
  • Let cool completely.

For the chocolate filling:

  • Add chocolate and pumpkin spice to a bowl.
  • Bring 3/4 cup heavy cream to a boil, then pour over the chocolate/spice mix and let sit for a minute.
  • Whisk to combine cream and chocolate into a smooth mix.
  • Whip 1 cup heavy cream with the sugar to stiff peaks.
  • Fold the cream into the chocolate.
  • Transfer the mousse into the cold crust, spread out evenly with an offset spatula, then chill in the fridge for 1.5 hours.

For the meringue topping:

  • Beat the egg whites until they start to foam, then, with the mixer running, gradually add the granulated sugar until you get glossy peaks.
  • Again with the mixer running, gradually add the powdered sugar.
  • Fold in the crystallized ginger.
  • Spread the topping onto the chocolate mousse tart and briefly burn with a torch.

Notes:

*Don’t use chocolate morsels; morsels have stabilizers in them that actually prevent them from melting.

      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). :)

      Thank you so much, Julia! That is so nice of you to say. The slice I cut out was actually in several pieces, I cut it out too thin initially and then sliced off more and more slivers until the opening in the tart looked the right size. :)

      You’re right, it’s sort of an update on the traditional s’mores flavors. :) Thank you so much for your kind words, they really mean a lot coming from you, your work is absolutely stunning!
