S’mores have forever been one of my favorite campfire treats. From s’mores milkshakes to my all-time favorite peanut butter s’mores dip, if it has marshmallows, chocolate and graham crackers, I’m in. So it was only a matter of time before I took this summertime dessert and gave it an elevated upgrade with my latest obsession: dot cakes (a.k.a. my cocktail cakes). Welcome to the party, S’mores Cocktail Cakes!

If you’ve been following along with my Cocktail Cakes series, you already know the concept: individual desserts served in shallow cocktail glasses, inspired by the viral dot cakes. This s’mores cake version stars moist chocolate cake layered with crushed graham crackers and a swirl of toasted marshmallow fluff.

They’re everything you love about s’mores sans the campfire. Serve ’em up at your next summer dinner party, backyard barbecue or 4th of July spread for the ultimate sweet finale.

Ingredients You’ll Need

We’re using the same chocolate cake I developed specifically for making dot cakes from scratch: moist, rich chocolate flavor that bakes up perfectly thin in a standard 13×9-inch pan. Here’s what you’ll need and why:

  • All-purpose flour, unsweetened cocoa powder, salt, baking soda and baking powder: The same dry ingredient foundation as my chocolate layer cake.
  • Unsalted butter at room temperature: Cold butter won’t cream properly and you’ll end up with a lumpy batter. Check out my foolproof trick for perfectly softened butter in under 10 minutes.
  • Sugar and egg: For sweetness and structure.
  • Sour cream: My secret ingredient. Just like in my vanilla cake mix cupcakes and coconut cake, sour cream is what keeps this cake incredibly moist and tender.
  • Vanilla extract: For flavor. Bonus points for using homemade vanilla extract!
  • Whole milk: Keeps the batter smooth and the finished cake tender. You can even use chocolate milk for more flavor!
  • Graham crackers: You’ll need ¾ cup crushed graham crackers, which is about 5 to 6 full sheets depending on how finely you crush them.
  • Marshmallow fluff: You’ll need one 7-oz. container of this spreadable fluff (also referred to as marshmallow creme).

First, Make the Chocolate Cake Layer

The batter comes together quickly with a stand mixer or electric handheld mixer. Start by creaming the butter and sugar until light and fluffy, then beat in the egg, sour cream and vanilla. Alternately add the milk and flour mixture in three increments until just combined.

Grease your 13×9-inch pan with cooking spray, pour in the batter and spread it into an even layer. Expect a much thinner layer of batter than a traditional 13×9 cake. I reworked my original chocolate cake recipe specifically for these dot-style cakes so the layer fits perfectly in the glasses. Since it’s thinner, it will bake up quickly.

Pull it the moment a toothpick comes out clean. Then comes the hardest part: waiting for it to cool completely before assembling.

Then, Assemble the S’mores Layers

Now comes the fun part: assembling the s’mores cakes! Here’s how the layers come together:

Layer 1: Chocolate cake. Once your cake has cooled completely, press your serving glass directly into the cake to stamp out your rounds. No knife required! Place one cake round in the bottom of each glass (these are the cocktail glasses I used).

Layer 2: Graham crackers. The easiest way to crush graham crackers is to toss them in a zip-top bag, squeeze all the air out and seal it tightly. Lay it flat on your counter and firmly roll back and forth with a rolling pin until you reach your desired texture. I like a mix of fine crumbs and small pieces for the best texture and crunch. Divide evenly among the glasses right on top of the cake layer.

Layer 3: Marshmallow fluff. Transfer the marshmallow creme to a sealable plastic bag (a piping tip is optional but makes it easier!) and pipe a generous layer over the graham cracker crumbs. Prefer to skip the bag? An offset spatula works great for spreading it on too. Don’t be shy here.

The best part: Toast it. I use a kitchen torch to toast the marshmallow creme until it’s golden brown and caramelized. If you don’t own one yet, consider this recipe your sign to get one. Once you have it, you’ll use it for everything from crème brûlée cheesecakes to toasting meringue on pies. The key is to keep it moving in small circles so it toasts evenly without burning.

Once torched, serve immediately for the ultimate gooey, toasty, chocolatey s’mores experience.

Equipment

Ingredients 

For the chocolate cake:

  • Cooking spray
  • 2/3 cup all-purpose flour
  • 1/4 cup unsweetened cocoa powder
  • 1/2 teaspoon baking soda
  • 1/4 teaspoon baking powder
  • 4 Tablespoons unsalted butter, at room temp
  • 2/3 cup sugar
  • 1 large egg
  • 1/4 cup sour cream
  • 1 1/2 teaspoons vanilla extract
  • 1/3 cup whole milk

For assembly:

  • 3/4 cup crushed graham crackers
  • 1 (7-oz.) container marshmallow creme/fluff

Instructions 

Make the chocolate cake:

  • Preheat the oven to 350°F. Grease a 13×9-inch baking pan with cooking spray.
  • In a large bowl, whisk together the flour, cocoa powder, baking soda and baking powder with ½ teaspoon kosher salt. 
  • In the bowl of a stand mixer fitted with the paddle attachment, cream together the butter and sugar until light and fluffy. Beat in the egg, then beat in the sour cream and vanilla extract until combined. 
  • Alternately add the milk and flour mixture in three increments until combined.
  • Transfer the batter into the prepared cake pan, spreading it into an even layer. 
  • Bake the cake until a toothpick inserted comes out clean, 18 to 22 minutes. Let the cake cool completely. 

Assemble the s'mores cocktail cakes:

  • Once you've stamped out the cakes, divide the crushed graham crackers among the cups.
  • Transfer the marshmallow creme to a sealable plastic bag. (Piping tip is optional!)
  • Pipe a layer of marshmallow creme atop the crushed graham crackers.
  • Use a kitchen torch to toast the marshmallow creme, then serve.

Kelly’s Notes

  • Container options: Coupe cocktail glasses give these the most elegant look, but small mason jars, ramekins or any small cup work too. The number of cakes you’ll get depends on the size of your container.
  • Serve immediately after torching for the ultimate gooey, toasty s’mores experience.
