Step‑by‑Step Instructions for Hot Chocolate Cupcakes with Marshmallow Buttercream
Step 1: Preheat the Oven
Begin by preheating your oven to 350°F (175°C). While the oven is heating, prepare two muffin tins by lining them with 22 paper liners. This will ensure that your Hot Chocolate Cupcakes are easily removable after baking and help them maintain their delightful shape.
Step 2: Mix the Batter
In a large mixing bowl, combine the chocolate fudge cake mix, milk, oil, eggs, hot cocoa packet, and instant dry pudding mix. Using a hand mixer, beat the mixture until it is smooth and well-blended, which should take about 2 minutes. The batter should be thick yet pourable, making it perfect for filling your cupcake liners.
Step 3: Fill the Muffin Cups
Once your batter is ready, carefully fill each muffin cup about three-quarters full with the chocolate mixture. This will give the cupcakes room to rise without overflowing. Slide the filled tins into the oven and bake for 15–18 minutes. A toothpick inserted into the center of a cupcake should come out clean when they’re done, indicating perfect doneness.
Step 4: Cool the Cupcakes
After baking, remove the cupcake tins from the oven and let them cool in the pans for about 5 minutes. Then, transfer the cupcakes to a wire rack to cool completely. Allowing them to cool ensures that your Hot Chocolate Cupcakes retain their moist texture and are ready for frosting.
Step 5: Prepare the Marshmallow Buttercream
While the cupcakes are cooling, it’s time to make the dreamy marshmallow buttercream. In a mixing bowl, cream together the softened butter, marshmallow fluff, vanilla extract, and salt until smooth and well combined. The mixture will become fluffy and sweet, creating the perfect topping for your cupcakes.
Step 6: Mix in Sugar and Cream
Gradually add the powdered sugar to the butter mixture, one cup at a time, mixing thoroughly after each addition. Alternate this with drizzling in the heavy cream until the frosting reaches a light and fluffy consistency. If the frosting feels too soft, add a bit more powdered sugar to achieve your desired thickness.
Step 7: Frost the Cool Cupcakes
Once your Hot Chocolate Cupcakes have cooled completely, generously frost each cupcake with the marshmallow buttercream using a spatula or piping bag. Ensure the frosting is spread evenly to maximize the fluffy texture, which will contrast beautifully with the rich chocolate cupcake base.
Step 8: Add Garnishes
To finish your delightful creations, sprinkle miniature marshmallow bits on top of the frosting and drizzle with chocolate syrup. This adds both texture and a touch of visual appeal, making your Hot Chocolate Cupcakes with Marshmallow Buttercream irresistible and ready to impress family and friends at any gathering.

Hot Chocolate Cupcakes with Marshmallow Buttercream Recipe FAQs
How do I choose the best ingredients for my hot chocolate cupcakes?
Absolutely! For the best results, use a high-quality chocolate fudge cake mix, as it provides great flavor and texture. Ensure that your milk is fresh and at room temperature for optimal mixing. Look for a marshmallow fluff that’s smooth and creamy, which will make your buttercream frosting light and airy.
What are the best storage methods and duration for these cupcakes?
You can keep your hot chocolate cupcakes in an airtight container at room temperature for up to 3 days. If you want them to last longer, refrigerate them for about a week, ensuring they’re well-covered to prevent drying out. For longer-lasting treats, freeze them without frosting for up to 3 months, which preserves their moist texture beautifully.
How can I freeze my cupcakes properly?
To freeze your hot chocolate cupcakes, follow these steps: First, let them cool completely to avoid ice crystals. Place the cupcakes in a single layer on a baking sheet and freeze them for about an hour. Once they’re firm, wrap each cupcake tightly in plastic wrap and then place them in a freezer-safe bag or container. This method keeps them fresh for up to 3 months. Just frost them after thawing to keep that marshmallow fluffiness intact!
What should I do if my frosting isn’t fluffy enough?
Very! If your marshmallow buttercream seems flat, it may need more powdered sugar for stability or additional heavy cream to lighten it up. Start by adding 1/4 cup of powdered sugar at a time until you reach your desired consistency—aiming for a light, airy texture. Also, ensure your butter is at room temperature before mixing to help achieve that perfect fluff!
Are these cupcakes suitable for people with allergies?
Yes, you can make these hot chocolate cupcakes more inclusive! For dairy allergies, substitute the milk with almond milk and use vegan butter along with a dairy-free marshmallow fluff. If there are egg allergies, the flax egg alternative (1 tablespoon of flaxseed meal mixed with 2.5 tablespoons of water for each egg) works wonderfully! Always check the labels on ingredients to ensure they meet specific dietary needs.
Can I make these cupcakes ahead of time?
Absolutely! You can bake the hot chocolate cupcakes a day in advance. Just allow them to cool completely, store them covered at room temperature, and frost them right before serving. This ensures they maintain their delightful texture and taste fresh for your guests!
