S'mores cupcake

I love toasting s’mores around a campfire and this dessert makes me feel like I’m fireside! They are great for birthday parties and other fall gatherings.


To make these, you’ll need:

  • Unfrosted chocolate cupcakes – I highly suggest my homemade recipe, but even a box mix will do in a pinch.
  • Egg whites – You’ll need these to make the fluffy marshmallow frosting. For best results, make sure there is no yolk mixed in.
  • Sugar and vanilla – These sweeten and flavor the marshmallow frosting.
  • Graham crackers, chocolate, and mini marshmallows – You’ll definitely want to decorate your cupcakes with these!
  • Chocolate syrup – This is needed to drizzle over the cupcakes.

How It’s Made

Start by making the frosting. Heat egg whites with sugar and vanilla over a double boiler (or a bowl set over a pot of boiling water).

Marshmallow Frosting

After you’ve heated the mixture and the sugar has dissolved, whisk those ingredients using an electric mixer for nearly 20 minutes until you have stiff, glossy peaks. I don’t suggest trying to do this by hand.

Then, it’s time for the fun part – decorating. Spread a thin layer of the frosting over a cooled chocolate cupcake – just enough to serve as glue for the graham cracker crumbs.

Then, invert the cupcake onto a plate of crushed graham crackers. They will stick to the frosting.

Grab your culinary torch and toast the frosting! Start off with the torch’s lowest heat setting so you don’t accidentally burn anything.

Top the cupcakes with a graham cracker square, chocolate, and mini marshmallows.

Tip: Depending on how sturdy and tall your frosting is, you may need to stick a toothpick or skewer behind the graham cracker and into the cupcake to help hold it up.

Expert Tips and FAQs


While you can use any cupcake liners for your cupcakes, I highly suggest trying baking cups. They look so cute!

(Tip: If you use my chocolate cupcake recipe, I suggest you stick a regular liner inside of the baking cup to guarantee that they look their best after the bake.)

If you use Paper Eskimo’s baking cups like I did, you won’t need a muffin tin! You can bake cups directly on a cookie sheet.

I love how they coordinate perfectly with the rest of the supplies that you’ll want for your party.

How long will these cupcakes last?

Once frosted and decorated, they are best when served within 24 hours.

What can I do with all of the leftover egg yolks?

I like to use mine to make homemade fruit curds (like my orange curd) and frozen custard. You can also freeze egg yolks to use in future recipes.

What can I do with leftover marshmallow frosting?

I make cookies with leftover buttercream frosting. With leftover marshmallow frosting, you can make meringues! Just pipe any extra onto a cookie sheet, sprinkle with any spices that you like, and bake at 200 F for 40 minutes. Turn the oven off and let them cool in the oven.

  • Candy thermometer
  • Stand mixer


  • 7 large egg whites
  • 2 cups sugar
  • 1 1/2 teaspoons vanilla extract
  • 4 graham cracker squares crushed
  • 12 unfrosted chocolate cupcakes
  • 12 graham cracker squares
  • 3 chocolate bars
  • 60 mini marshmallows
  • chocolate syrup to taste


  • Combine egg whites, sugar, and vanilla extract in the metal mixing bowl of your stand mixer and set over a pot filled with boiling water on a range, creating a double boiler.
  • Whisk by hand for a few minutes until the mixture reaches 110 F on a candy thermometer.
  • Place the bowl on a stand mixer fitted with the whisk attachment. Whisk on medium speed for 10 minutes.
  • Increase to high speed and whisk until stiff glossy peaks form, about 5 to 10 minutes more.
  • Spread a thin layer of marshmallow frosting over each cupcake.
  • Dip each cupcake into crushed graham crackers.
  • Use a piping bag fitted with a large round tip to pipe a generous swirl of frosting on each cupcake, leaving a small edge of graham cracker crumbs showing.
  • Using a culinary torch, toast the marshmallow frosting.
  • Top each cupcake with a graham cracker square, a piece of chocolate, mini marshmallows, and chocolate syrup.
  • Serve within 24 hours (otherwise the graham cracker will get soggy).



When making the marshmallow frosting:
  • Make sure the inside of the bowl is totally dry before beginning.
  • Make sure there are no egg yolks mixed in with the egg whites.
  • Keep on whisking – don’t stop early.
If the graham cracker doesn’t stay upright on top of the cupcakes, you can place a small toothpick behind it to support it.
