S’more Layer Cake

Hey there! You may be wondering what this recipe for S’more Layer Cake is doing on a paleo-ish food blog. Well…. it dates back to when I wasn’t a paleo-ish blogger, and it’s one of our favorites. 

Eventually I’d like to clean it up and make it (at least) gluten and dairy-free, but in the meantime it’ll stay and have a home here on my blog as totally-worth-it recipe we’d indulge in.

If you’ve been reading my blog for a while you’ll know that even though we’re pretty clean eaters, we like to indulge on birthdays. We also take our birthday cakes very seriously. 

Birthday cake planning is talked about year-round, and the girls have cakes planned out until they’re tweens.

Luckily girls are fickle, so I don’t have to make my shopping list until a couple weeks beforehand, which is usually when they change their minds.

My marshmallow-obsessed middle child turned four over the holiday weekend, and for the past month or so she’d been requesting a s’more birthday cake.

Just a couple weeks after she’d made her decision, I got Deb Perelman’s book, The Smitten Kitchen Cookbook, in the mail.

See that cake up there? It’s Deb’s S’more Layer Cake. I almost died when I saw it. No, really.

Decision made.

This week we also tried those tacos (spaghetti squash and beans!) as well as her vinegar slaw with cucumbers and dill. Those were especially good after the rich, Thanksgiving food we’d been eating all weekend.

Nothing like a bowl of lightly pickled cabbage to set you back on track. I actually loved it, though, and it was a surprisingly good addition to those tacos.

Alright, back to the cake. I packed my kitchen torch and a number four candle and made the cake up at my parents house over the weekend. My little miss was so excited!

We were, too. That cake was TO. DIE. FOR. The cake part tasted just like graham crackers, and that meringue smelled just like roasted marshmallows when it was torched.


The only thing I’d do differently is make more frosting (I didn’t feel like it made enough to make those dollop things in Deb’s photo), and use dark chocolate in the filling instead of milk chocolate.

 The Smitten Kitchen Cookbook is pretty amazing, guys. That was kind of a given, though. Smitten Kitchen was one of the first food blogs I started reading, and Deb always delivers. Always.

A few food bloggy friends also felt that way, too! For more gushing over this book and some rockstar recipes go to…

S'more Layer Cake

Yield: 16 servings

If you love s'mores, then this cake is a MUST BAKE. And if you don't have a kitchen torch, ask for one for your birthday. And then make this cake. It's absolutely fantastic with toasted marshmallow frosting.


Cake Layers

  • 16 tablespoons unsalted butter (2 sticks)
  • 2 cups all-purpose flour
  • 2 cups honey (not cinnamon-sugar topped) graham-cracker crumbs, finely processed to a powder (about 14 2 1/2-by-4 7/8-inch sheets)
  • 2 teaspoons baking powder
  • 3/4 teaspoon baking soda
  • 3/4 teaspoon table salt
  • 1/2 teaspoon ground cinnamon
  • 2/3 cup granulated sugar
  • 1 cup dark brown sugar
  • 4 large eggs, at room temperature
  • 2 cups buttermilk, well shaken (or 1 1/3 cups milk and 2/3 cup sour cream)


  • 1/2 pound milk chocolate, chopped small
  • 3/4 cup heavy cream
  • 2 pinches of salt


  • 4 large egg whites
  • 1 cup granulated sugar
  • 1/4 teaspoon cream of tartar
  • 1 teaspoon pure vanilla extract


  1. Preheat your oven to 350 degrees F.
  2. Butter two 9-inch round cake pans, and line them with circles of parchment paper, then butter or coat with nonstick cooking spray.
  3. In a medium bowl, whisk together flour, graham-cracker crumbs, baking powder, baking soda, salt, and cinnamon. Set aside.
  4. In a large mixing bowl, cream butter and sugars together until light and fluffy. Add eggs one at a time, scraping the bowl down after each addition.
  5. Add a third of the dry ingredients, then half the buttermilk, a third of the dry ingredients, the remaining buttermilk, and then the remaining dry ingredients, mixing between additions until combined. Scrape down bowl, and mix again briefly if needed.
  6. Divide batter between prepared cake pans, smoothing tops.
  7. Bake until a toothpick inserted into the center comes out clean, about 30-35 minutes. Cool in pan on rack, then run a knife between the cake edges and pans before inverting each layer on a rack, discarding the parchment paper, and flipping back upright onto a rack. Let cool completely, a process you can speed up in the fridge.
  8. Make the filling: Place the chocolate in a heatproof bowl. Combine the heavy cream and salt in a small saucepan, and bring to a simmer.
  9. Pour over the chocolate, and let sit for 1 minute, then whisk until smooth. Set bowl over another bowl filled with ice water, and stir it until it firms up to a spreadable consistency. You can also let it cool down in the fridge, stirring it from time to time so it thickens evenly.
  10. Prepare the cake: Arrange a single cake layer on a serving platter or cake stand. For a neat-looking cake, use a long serrated knife to level the top gently, taking off only the domed part (which shouldn't be much); place scraps in a bowl where husbands and other housemates can enjoy the preview.
  11. Spread chocolate thickly over bottom layer. Place the top layer over bottom layer. Once again, for a neater appearance, you can level the top off the cake in the same manner, but I won't tell anyone if you don't share the scraps. Baking is exhausting work, after all.
  12. Make the frosting: Place egg whites, granulated sugar, and cream of tartar in the heatproof bowl of an electric mixer. Set over a saucepan with simmering water. Whisk constantly until sugar is dissolved and whites are warm to the touch, about 3 minutes.
  13. Transfer the bowl to an electric mixer fitted with the whisk attachment, and beat, starting at low speed, gradually increasing to high, until stiff, glossy peaks form, 4-7 minutes. Add vanilla, and mix until combined. You'll want to use this immediately.
  14. Frost the cake: Spread a thin layer of the frosting over the top and sides, covering all of the crumbs (and binding them to the cake). Transfer the cake to the fridge for 5 or 10 minutes, to let it set a bit, then generously coat the top and sides with additional frosting.
  15. Pipe the remaining frosting (if you have it) in marshmallow-like dollops decoratively over the top. (I didn't do this part, so I have no wisdom to share.)
  16. With a kitchen torch on a low setting, lightly brown the top, creating a toasted-marshmallow effect.


Nat's Notes:vI should have used parchment in my pans, but I didn't. A few chunks came out of the tops, but with the fluffy frosting, you'd never know. Honestly, I secretly like when it does that because I get to taste more of the cake.
