S'mores Cupcakes Recipe | Rich Chocolate & Toasted Marshmallow — Kelvin's Kitchen
Jump to Recipe Print Recipe

This Decadent S'mores Cupcakes is an absolute crowd-pleaser and so much easier to make than you'd think. Rich, indulgent, and perfectly sweet, it's the kind of treat that disappears fast. Get ready for everyone to ask you for the recipe!

Did You Know?

The combination of graham crackers, chocolate, and marshmallows first appeared in the early 1900s. The recipe was popularized through the Girl Scouts' handbook, and the name S'mores comes from wanting 'some more' of these irresistible treats.

Pro Tips

Bring eggs and butter to room temperature before mixing for the smoothest batter. Test doneness with a toothpick in the center. A few moist crumbs clinging to it means it is ready.

Frequently Asked Questions

1. What type of chocolate cake base works best for s'mores cupcakes?

A moist, dark chocolate cake base using Dutch-process cocoa and hot coffee gives the deepest chocolate flavor that complements the marshmallow and graham cracker components.

2. How do I make the marshmallow frosting?

Swiss meringue buttercream made with marshmallow fluff gives the smoothest result. Alternatively, make a simple marshmallow frosting by whipping fluff with butter and powdered sugar.

3. How do I get the toasted marshmallow look on top?

Use a kitchen torch to toast the marshmallow frosting after piping. Hold the flame 2-3 inches away and move constantly to create an even golden-brown color without burning.

4. Can I use a broiler instead of a kitchen torch?

Yes, but watch constantly — marshmallow frosting can go from golden to burnt in seconds under a broiler. Keep cupcakes 4-6 inches from the element and rotate the tray.

5. How do I add the graham cracker component?

Crush graham crackers and mix into the cupcake batter, press a layer into the bottom of the liner before adding batter, or use as a crunchy topping on the frosting.

6. Can I fill the cupcakes with marshmallow?

Yes — use an apple corer or piping tip to hollow out the center of baked cupcakes, then pipe in marshmallow fluff before frosting. This creates a gooey surprise inside.

7. Should I use milk chocolate or dark chocolate?

Milk chocolate is more traditional for s'mores and appeals to most palates. Dark chocolate works for a more sophisticated, less sweet version. Use chocolate ganache for the richest result.

8. How far ahead can I make s'mores cupcakes?

Bake the cupcakes a day ahead and store covered at room temperature. Frost and torch the marshmallow the day of serving for the best texture and appearance.

9. Why did my cupcakes sink in the middle?

Overmixing the batter, opening the oven too early, or too much leavening can cause sinking. Mix until just combined and avoid opening the oven during the first 15 minutes.

10. How do I store s'mores cupcakes?

Store at room temperature in an airtight container for 2-3 days. The marshmallow topping is best fresh. Do not refrigerate — cold temperatures make the cake dry.

Ingredients Method Notes

Ingredients
  

  • 9-10 graham cracker sheets 1 cup crumbs
  • ½ cup all-purpose flour
  • 1 ½ teaspoon baking powder
  • ½ teaspoon salt
  • ½ cup unsalted butter softened
  • ¾ cup granulated sugar
  • 2 large eggs
  • 1 teaspoon vanilla extract
  • ½ cup milk
  • ½ cup mini chocolate chips

Method
 

  1. Preheat your oven to 350°F (175°C) and line a muffin tin with cupcake liners. Crush graham crackers into fine crumbs. Whisk together the graham cracker crumbs, flour, baking powder, and salt. In a large bowl, beat the butter and sugar until light and fluffy. Add the eggs one at a time, beating well after each addition. Mix in the vanilla extract. Gradually add the dry ingredients alternating with the milk. Fold in the mini chocolate chips. Fill each cupcake liner about two-thirds full. Bake for 18-20 minutes, or until a toothpick comes out clean. Allow to cool completely.
  2. In a small saucepan, heat the heavy cream until it just begins to simmer. Pour the hot cream over the chocolate chips in a bowl. Let it sit for a minute, then stir until smooth and glossy. Allow the ganache to cool slightly.
  3. In a large bowl, combine the marshmallow fluff, softened butter, and powdered sugar. Beat until light and fluffy. Add vanilla extract and mix until combined.
  4. Use a small knife or cupcake corer to remove a small piece from the center of each cupcake. Fill the hole with chocolate ganache. Pipe or spread the marshmallow frosting on top. Use a kitchen torch to lightly toast the marshmallow frosting. Sprinkle with graham cracker crumbs and drizzle with extra chocolate ganache.
