  1. Preheat the oven to 350 degrees F (177 degrees C). Line a 12-cup muffin pan with cupcake liners. Line a second pan with 2 liners. Set aside.


  1. In a large bowl, whisk the cocoa powder, flour, baking soda, baking powder, and salt together until thoroughly combined. Set aside.

  2. In a medium bowl, whisk the eggs, sugar, brown sugar, oil, and vanilla together until completely smooth. Pour half of the wet ingredients into the dry ingredients. Then half of the buttermilk.

  3. Gently stir for about 5 stirs. Repeat with the remaining wet ingredients and buttermilk. Stir until just combined. Do not overmix.

  4. Pour or spoon the batter into the liners. Fill only halfway to avoid spilling over the sides.

  5. Bake in batches for 18 to 19 minutes or until a toothpick inserted in the center comes out clean. Allow cooling completely before continuing.

Marshmallow Filling:

  1. In a medium bowl using a handheld or stand mixer fitted with a paddle attachment, beat the butter, marshmallow creme, vanilla, and cream on medium speed until completely smooth. Add 3/4 cup confectioners’ sugar and the salt slowly with the mixer running on low, then increase the speed to high and beat for 1 minute. If it looks too thin, add 1/4 cup more confectioners’ sugar. Refrigerate the filling until ready to use.

  2. With a handheld or stand mixer fitted with a paddle attachment, beat the butter on medium speed until creamy for about 2 minutes.

  3. Gradually add the sifted sugar/cocoa powder alternately with the heavy cream and vanilla. Beat on low speed after each addition.

  4. Once all added, beat on high speed until creamy and combined for at least 2 minutes. Add a pinch of salt if the frosting is too sweet. Set aside until ready to use.

To assemble the cupcakes:

  1. Using a sharp knife, cut a circle/hole into the center of the cupcake to create a little pocket about ¾-inch deep.

  2. Place 1 spoonful of marshmallow filling inside and top with the piece of cupcake you removed to seal.

  3. Frost the cupcakes however you like. Sprinkle with crushed graham crackers.

  4. Toast the marshmallows on a large baking sheet on one of the top oven racks with your oven on the broil.

  5. Once browned, quickly remove and let cool for 5 minutes. Scoop from the baking sheet using a spatula and place it on top of the frosted cupcakes.

  6. Enjoy immediately while the marshmallows are nice and gooey.

Crucial Technique for Perfecting Marshmallow-Filled S'mores Cupcakes

When preparing the marshmallow filling for your cupcakes, ensure that your butter is at room temperature. This will make it easier to blend with the marshmallow creme and will result in a smoother, creamier filling. Also, when toasting the marshmallows for the topping, keep a close eye on them as they can easily burn under the broiler. It's best to stay by the oven and check them every few seconds.

Time-Saving Tips for Making S'mores Cupcakes

Prepare the filling: Make the marshmallow filling ahead of time and store it in the refrigerator until you're ready to use it. This will save you time when assembling the cupcakes.

Organize ingredients: Before you start baking, gather all the ingredients and measure them out. This will help streamline the baking process and prevent any last-minute scrambling for ingredients.

Use a piping bag: When filling the cupcakes with the marshmallow filling, use a piping bag to easily and quickly add the filling to each cupcake.

Bake in batches: If your muffin pan can only hold 12 cupcakes at a time, bake the cupcakes in batches to save time and ensure even baking.

Chill the frosting: If you have time, chill the frosting in the refrigerator for a short while before frosting the cupcakes. This can help the frosting hold its shape better and make it easier to work with.

Pre-crush graham crackers: Save time by pre-crushing the graham crackers ahead of time, so they're ready to sprinkle on top of the frosted cupcakes.

Substitute Ingredients For Marshmallow-Filled S’mores Cupcakes Recipe

  • cocoa powder - Substitute with carob powder: Carob powder has a similar flavor profile to cocoa powder and can be used as a 1:1 replacement in this recipe. It also adds a unique sweetness and depth to the cupcakes.

  • all purpose flour - Substitute with whole wheat flour: Whole wheat flour can be used as a substitute for all-purpose flour to add a nuttier flavor and additional nutrients to the cupcakes.

  • baking soda - Substitute with baking powder: If you don't have baking soda, you can use baking powder as a substitute, but you will need to use more of it. Use 3 times the amount of baking powder for the same leavening effect.

  • baking powder - Substitute with yeast: Yeast can be used as a substitute for baking powder, but it will require additional time for the dough to rise. Use 1 teaspoon of yeast for every 1 1/4 teaspoons of baking powder.

  • eggs - Substitute with applesauce: Applesauce can be used as a substitute for eggs to add moisture and binding properties to the cupcakes. Use 1/4 cup of applesauce for every egg.

  • granulated sugar - Substitute with honey: Honey can be used as a natural sweetener in place of granulated sugar. It also adds a unique flavor to the cupcakes.

  • light brown sugar - Substitute with coconut sugar: Coconut sugar can be used as a substitute for light brown sugar to add a caramel-like flavor to the cupcakes.

  • vegetable oil - Substitute with applesauce: Applesauce can be used as a substitute for vegetable oil to reduce the fat content in the cupcakes. Use an equal amount of applesauce as the amount of vegetable oil called for in the recipe.

  • buttermilk - Substitute with milk + vinegar: You can make a buttermilk substitute by combining 1 cup of milk with 1 tablespoon of vinegar or lemon juice. Let it sit for 5-10 minutes before using.

  • unsalted butter - Substitute with coconut oil: Coconut oil can be used as a substitute for unsalted butter to add a hint of coconut flavor to the cupcakes.

  • marshmallow creme - Substitute with fluffernutter spread: Fluffernutter spread, a combination of marshmallow and peanut butter, can be used as a substitute for marshmallow creme to add a unique flavor to the filling.

  • confectioner's sugar - Substitute with powdered erythritol: Powdered erythritol can be used as a sugar-free substitute for confectioner's sugar in the filling and frosting.

  • heavy cream - Substitute with coconut cream: Coconut cream can be used as a dairy-free substitute for heavy cream to add richness to the filling and frosting.

  • milk chocolate - Substitute with dark chocolate: Dark chocolate can be used as a substitute for milk chocolate to add a richer and slightly bitter flavor to the frosting.

  • marshmallows - Substitute with toasted coconut flakes: Toasted coconut flakes can be used as a substitute for marshmallows to add a crunchy and nutty topping to the cupcakes.

  • graham crackers - Substitute with digestive biscuits: Digestive biscuits can be used as a substitute for graham crackers to add a slightly different texture and flavor to the cupcakes.

Presenting the Perfect Marshmallow-Filled S'mores Cupcakes

  1. Elevate the cupcake: Place the cupcake on a pristine white plate to showcase its decadence and allure. Ensure the cupcake is centered and positioned with precision.

  2. Garnish with graham cracker dust: Sprinkle a delicate dusting of graham cracker crumbs around the base of the cupcake to add a touch of rustic charm and a subtle crunch.

  3. Create a marshmallow nest: Arrange the toasted marshmallows in a nest-like formation on top of the cupcake, creating a visually stunning and inviting presentation.

  4. Drizzle with chocolate sauce: Artfully drizzle a rich, velvety chocolate sauce around the base of the cupcake, adding a touch of elegance and decadence to the presentation.

  5. Add a touch of gold leaf: For a luxurious touch, delicately place a small, edible gold leaf on top of the marshmallow nest, adding a hint of opulence to the overall presentation.

  6. Serve with a side of vanilla bean ice cream: Accompany the cupcake with a quenelle of vanilla bean ice cream on the side, adding a refreshing and complementary element to the indulgent dessert.

Storing and Freezing S'mores Cupcakes

  • Allow the cupcakes to cool completely before storing or freezing.
  • Store leftover cupcakes in an airtight container at room temperature for up to 3 days.
  • For longer storage, place the cooled cupcakes in a freezer-safe container or zip-top bag and freeze for up to 2-3 months.
    • If freezing, it's best to freeze the cupcakes unfrosted and without the marshmallow topping.
    • Thaw the frozen cupcakes in the refrigerator overnight or at room temperature for a few hours before frosting and adding the marshmallow topping.
  • If you have leftover marshmallow filling or chocolate frosting, store them separately in airtight containers in the refrigerator for up to 5 days.
    • Allow the filling and frosting to come to room temperature and give them a quick stir before using.
  • To maintain the best texture and flavor, add the toasted marshmallow topping just before serving, as it can become sticky and lose its shape over time.

Reheating Leftover S'mores Cupcakes

  • To reheat leftover marshmallow-filled s'mores cupcakes, start by preheating your oven to 350°F (175°C). This temperature will help warm up the cupcakes without drying them out or making them too crispy.

  • Place the cupcakes on a baking sheet lined with parchment paper or aluminum foil. This will prevent the cupcakes from sticking to the pan and make cleanup easier.

  • If the marshmallow filling has hardened, you can place a small piece of butter or a teaspoon of heavy cream on top of each cupcake before reheating. This will help soften the filling and make it gooey again.

  • Cover the baking sheet with aluminum foil to help trap in moisture and prevent the cupcakes from drying out. This is especially important if the cupcakes have been stored in the refrigerator and may have dried out slightly.

  • Place the covered baking sheet in the preheated oven and reheat for 5-7 minutes, or until the cupcakes are warmed through and the marshmallow filling is soft and gooey.

  • If you want to refresh the graham cracker topping, you can sprinkle some crushed graham crackers on top of the cupcakes before reheating. This will give them a nice crunch and added flavor.

  • For a quick and easy reheating option, you can also microwave individual cupcakes for 10-15 seconds on high power. Just be sure to watch them closely so they don't overheat and become too soft or mushy.

  • If you want to reheat the cupcakes without the marshmallow filling, you can remove the filling with a spoon or piping bag before reheating. This will allow the chocolate cupcake to warm up without the filling becoming too runny or messy.
