Homemade graham cracker crust, rich chocolate ganache and a billowy toasted meringue come together to make the ultimate s'more tart! Good thing it's as easy as it is delicious!

It's here. It's officially that proverbial time of year to make something s'more. Why officially? Because I pretty much decided so.

If you've been hanging around these parts for any length of time, you've probably picked up on my affinity for all things s'more. I've made s'more doughnuts, s'more sandwich cookies... Seriously, I could write this list forever. I kid you not, FOREVER.

And, let's be honest, what's NOT to love about s'mores? Can you REALLY beat chocolate, marshmallow and graham cracker? FYI, the answer you're looking for is no. Just no.

Unless you were going to say chocolate, marshmallow and graham cracker alongside a crackling fire in the dead of winter with a mug of hot cocoa. In which case, let's be best friends?

Prefer to watch the process?

How to make this s'more tart

First, make the graham cracker crust.

In the bowl of a stand mixer, beat the butter for the graham cracker crust until smooth. Add the brown sugar and honey, and continue beating until the mixture is once again smooth.

Add the remaining ingredients for the crust and beat until it pulls away from the sides and clumps into a single ball. Wrap the dough in plastic wrap and allow to chill for at least 30 minutes or up to 2 days (depending on how far in advance you make it).

On a lightly floured surface, work the dough for the crust with your hands until malleable.

Roll the dough out on a piece of parchment paper until it's slightly larger than your 14" x 5" pan. Gently flip the dough into the pan and press it into the bottom and sides.

Don't worry if it breaks apart or cracks; this dough presses back together beautifully. Just use your fingers to press together any cracks and excess dough to fill in holes.

Trim away any excess left around the edges. Generously prick the bottom, and bake at 350F with pie weights for 10-12 minutes, or until golden brown.

Second, make the chocolate ganache filling.

To make the ganache, heat the cream until almost boiling (this can be done in a microwave if you prefer not to mess with the stove). Chop the chocolate into fine pieces and pour the hot cream over it.

Allow the hot cream and chocolate to sit for a couple of minutes so that the chocolate softens. Gently stir the ganache with a spatula (a whisk creates too many air bubbles) until completely smooth.

Pour the ganache into the cooled tart shell and spread evenly. Wrap with plastic wrap pressed down onto the surface of the ganache, and refrigerate for at least 2 hours.

Fourth, make the meringue.

To make the meringue topping, whisk together the egg whites and granulated sugar in the bowl of a stand mixer placed over a pot of boiling water (a double boiler).

Whisking occasionally, heat the mixture until the sugar has dissolved and the mixture is hot to the touch.

Move the bowl to your stand mixer, add the vanilla, and whisk on high (using the whisk attachment) until billowy, and the meringue holds a stiff peak.

Finally, assemble the tart.

Remove the tart from the refrigerator, and spread the meringue evenly across the top.

I used the back of a small spoon to create the back and forth pattern on the top, but you can really style the meringue however you like. Toast with a chef's torch and serve immediately.

Tips for making the perfect tart

Looking to work ahead? The the graham cracker dough can be made 2 days in advance and a baked shell filled with ganache can last up to a week. Both should be refrigerated.
Graham cracker dough is too dry: Sometimes this dough winds up a little dry. If that happens to you, you can easily fix this by dampening your hands with water and knead that little bit of moisture into the dough. The dough has reached the right consistency when it forms one cohesive ball without being sticky.
Easily transfer the dough: The secret to easily transferring the graham cracker crust to the pan is to roll it out on a piece of parchment. Pick up the parchment paper and gently turn it out over the pan.
Baking an empty tart or pie shell: Whenever you’re baking an empty pie or shell tart, be sure to use a pie weight of some sort. This will keep the dough from rising, pulling way from the pan and/or forming air pockets. Pie weights are available to purchase or you can make your own by placing parchment paper on your crust and covering it with uncooked rice or dry beans.
Meringue won't whip up: Sometimes, no matter what you do, your meringue won't whip up to stiff, billowy peaks. The most common culprit: Grease. Any bit of grease in your mixing bowl, no matter how miniscule, can keep your meringue from reaching stiff peaks. To avoid this, make sure to give your mixing bowl a fresh clean before making the meringue.
Browning the meringue without a torch: If you don’t have a culinary torch on hand, you can brown your meringue in the oven under the broiler. Just be sure to keep an eye on it so it doesn’t burn.

Oh hey there! You might have noticed a number of updated posts recently. That's because summer is often a time where blogs like mine see less traffic, and what better time to improve the content I already have than a time where I don't have to worry quite so much about creating totally new things.

But improving doesn't mean forgetting where I was in my photography journey this time three years ago. Spoiler alert: It's not nearly as far along as I am now.

I was still in my "wash out all the shadows" phase. So enjoy the photo below of this post circa 2016!
