How to Make S’mores Cupcakes with Marshmallow Buttercream Frosting

Step 1: Preheat the Oven

Preheat your oven to 350°F (175°C). Line your muffin tin with cupcake liners to prevent sticking.

Step 2: Prepare the Graham Cracker Mixture

In a mixing bowl:
1. Combine graham cracker crumbs, 5 tablespoons of granulated sugar, and melted butter.
2. Mix until well combined; it should resemble wet sand.

Step 3: Make the Batter

In another large bowl:
1. Whisk together granulated sugar, flour, cocoa powder, baking powder, baking soda, and salt.
2. Add the egg, milk, oil, vanilla extract, and boiling water. Mix until smooth.

Step 4: Combine Mixtures

Gently fold the graham cracker mixture into the cupcake batter until just combined.

Step 5: Bake the Cupcakes

Pour the batter evenly into the prepared muffin tins. Bake for about 20-25 minutes or until a toothpick inserted comes out clean. Let them cool on a wire rack.

Step 6: Prepare Marshmallow Buttercream Frosting

In a separate bowl:
1. Beat room temperature butter until creamy.
2. Gradually add marshmallow creme and mix until fluffy.
3. Add vanilla extract and salt; slowly incorporate powdered sugar until smooth.

Step 7: Frost Your Cupcakes

Once cooled:
1. Generously pipe or spread marshmallow frosting on each cupcake.
2. Drizzle thick chocolate sauce over the top.

How to Perfect S’mores Cupcakes with Marshmallow Buttercream Frosting

To ensure your S’mores Cupcakes come out perfectly every time, follow these helpful tips.

  • Use Room Temperature Ingredients: Ensure your butter, eggs, and milk are at room temperature for better mixing and texture.

  • Don’t Overmix the Batter: Mix until just combined to keep the cupcakes light and fluffy; overmixing can lead to dense cupcakes.

  • Bake Evenly: Rotate your cupcake pan halfway through baking for even cooking and browning.

  • Cool Completely Before Frosting: Allow your cupcakes to cool completely before adding marshmallow buttercream frosting to prevent melting.

Best Side Dishes for S’mores Cupcakes with Marshmallow Buttercream Frosting

These S’mores Cupcakes shine on their own but can be enhanced with these delicious side dishes.

  1. Fruit Skewers: Fresh fruit skewers add a refreshing contrast and balance the sweetness of the cupcakes.

  2. Chocolate Fondue: Set up a chocolate fondue station where guests can dip strawberries or bananas alongside their cupcakes.

  3. Mini Cheesecakes: Individual mini cheesecakes provide another rich dessert option that complements the flavors of s’mores well.

  4. Ice Cream Sundae Bar: Create an ice cream sundae bar with various toppings, allowing guests to customize their desserts.

  5. Pineapple Upside-Down Cake: The caramelized pineapple brings a tropical twist that pairs nicely with the flavors of chocolate and marshmallow.

  6. S’mores Dip: A gooey s’mores dip served warm with graham crackers provides an interactive dessert experience alongside your cupcakes.

Common Mistakes to Avoid

Making S’mores Cupcakes with Marshmallow Buttercream Frosting can be a breeze, but there are common pitfalls to watch out for.

  • Using the wrong cocoa powder: Always opt for unsweetened cocoa powder that is natural, not Dutch-processed. This ensures the right flavor and texture in your cupcakes.
  • Not measuring ingredients accurately: Accurate measurements are crucial for baking. Use proper measuring cups and spoons to avoid too much or too little of any ingredient.
  • Skipping the boiling water step: This step helps activate the cocoa powder and keeps the batter moist. Don’t skip it!
  • Overmixing the batter: Mix just until combined to keep your cupcakes light and fluffy. Overmixing can lead to dense cupcakes.
  • Ignoring the frosting temperature: Ensure your butter is at room temperature before making the marshmallow buttercream. Cold butter won’t whip properly, affecting texture.
