Ingredients & Why They Work
Each ingredient in this Hot Chocolate Cupcakes with Marshmallow Frosting Recipe brings something special to the table. The combo of dry cocoa powder and sweet hot cocoa mix amps up the chocolate flavor, while the buttermilk keeps the cupcakes super moist and tender. The frosting’s magic comes from that classic marshmallow fluff, lending a dreamy texture you’ll want to scoop right off the beaters.

- All-purpose flour: Provides the perfect structure with just enough bite for a soft cupcake.
- Sugar: Sweetens evenly and helps with that moist crumb.
- Cocoa powder: Adds that deep chocolate richness and a hint of pleasant bitterness to balance sweetness.
- Hot cocoa mix: Brings in that nostalgic, sweet hot chocolate twist making these cupcakes unique.
- Salt: Enhances the chocolate flavor and balances the sweetness perfectly.
- Baking powder & baking soda: These leavening agents work together for a tender, fluffy cupcake rise.
- Vegetable oil: Keeps the cakes moist—oil just blends better than butter here for texture.
- Buttermilk: Adds tanginess and tenderness, reacts with baking soda for lightness.
- Eggs: Bind everything together and give structure.
- Hot water: Activates the cocoa powder and hot cocoa mix for enhanced flavor and helps make the batter smooth.
- Salted butter (for frosting): Adds creaminess and a slight savory edge to balance the sweet marshmallow topping.
- Powdered sugar: Makes the frosting smooth and sweet without graininess.
- Marshmallow fluff: The star of the frosting, lending its cloud-like texture and sweet flavor.
- Vanilla extract: Enhances all the flavors in the frosting with a warm note.
- Milk: Optional for thinning out the frosting to your desired consistency.
- Optional garnishes (Mallow Bits, mini marshmallows, hot cocoa mix, melted chocolate): Add visual fun, texture, and extra chocolate or marshmallow goodness.
Make It Your Way
I love mixing things up with this Hot Chocolate Cupcakes with Marshmallow Frosting Recipe depending on the season or mood. Sometimes I’ll add a pinch of cinnamon or espresso powder into the batter to deepen the flavor, or swap out the marshmallow fluff for a homemade vanilla buttercream for a different frosting texture. You should definitely feel free to play around with it!
- Variation: For a peppermint twist during the holidays, I stir in a few drops of peppermint extract into the frosting and top with crushed candy canes—totally festive and refreshing.
Step-by-Step: How I Make Hot Chocolate Cupcakes with Marshmallow Frosting Recipe

Step 1: Prep and Mix Your Dry Ingredients
First things first, I preheat my oven and line a muffin tin with cupcake liners. Then, in a large bowl or stand mixer, I combine the flour, sugar, cocoa powder, hot cocoa mix, salt, baking powder, and baking soda. Whisking these dry ingredients well ensures that every cupcake has an even chocolate flavor and no clumps.
Step 2: Whisk Together Wet Ingredients Separately
In a separate bowl, I whisk the vegetable oil, buttermilk, and eggs until they’re well combined. This step helps avoid overmixing later, which can make cupcakes tough.
Step 3: Bring Wet and Dry Ingredients Together
Next, pour the wet ingredients into the dry and stir gently until just combined, making sure to scrape down the sides of the bowl to bring everything in. This batter should be nice and smooth—with that classic chocolate scent filling your kitchen.
Step 4: Add Hot Water Slowly
Slowly add the hot water while stirring; this step helps activate the cocoa powder and hot cocoa mix, lending the cupcakes their moist and tender crumb. Try not to overmix; just stir until the batter comes together beautifully.
Step 5: Bake and Cool
Fill each cupcake liner about ⅔ full and pop them into the oven for 15-17 minutes. I like to test doneness with a toothpick—when it comes out clean or with a few crumbs, they’re ready. Be patient and let the cupcakes cool completely before frosting to avoid a melty mess.
Step 6: Make the Marshmallow Frosting
While the cupcakes cool, whip up the frosting. Using a stand mixer with the paddle attachment, beat the softened salted butter until light and fluffy—about a minute. Add powdered sugar, marshmallow fluff, and vanilla extract, blending until combined. Then crank it up to high speed for a couple of minutes to get that ultra-light texture. If the frosting feels too stiff, don’t hesitate to add a tablespoon of milk to loosen it up.
Step 7: Frost and Garnish
Use a knife or piping bag to generously top each cooled cupcake. I love sprinkling Mallow Bits or mini marshmallows on top, sometimes dusting a pinch of hot cocoa mix or drizzling melted chocolate for an extra wow factor. These little finishing touches make them irresistible!
Top Tip
From countless baking sessions, I’ve learned a few tricks that make this Hot Chocolate Cupcakes with Marshmallow Frosting Recipe foolproof and even better than expected—especially if you’re making them for a crowd or a special treat.
- Use Room Temperature Ingredients: I always make sure eggs and butter are at room temp for smoother batter and creamier frosting.
- Don’t Skip the Hot Water: Adding hot water not only makes mixing easier but really amps up the cocoa flavor and ensures moist cupcakes.
- Cool Completely Before Frosting: Hot cupcakes will cause your marshmallow frosting to melt and slide off—patience here makes a huge difference!
- Scrape Down Sides Often: While mixing both batter and frosting, really take your time scraping down the bowl for fully blended ingredients and the best texture.
How to Serve Hot Chocolate Cupcakes with Marshmallow Frosting Recipe

Garnishes
I’m a big fan of topping these cupcakes with mini marshmallows or Mallow Bits because they add a delightful chew and visual appeal. Sometimes a dusting of hot cocoa powder or a drizzle of melted chocolate really takes it over the top, especially if you want to impress guests with an extra touch.
Side Dishes
These cupcakes pair beautifully with a warm cup of coffee or milk, and for a brunch spread, I like serving them alongside fresh berries or a light fruit salad to balance the richness.
Creative Ways to Present
For birthdays or cozy gatherings, I’ve layered these cupcakes in a glass trifle bowl, adding whipped cream and chocolate shavings between layers for a stunning display. You can also serve them on a tiered cupcake stand with festive cupcake liners to make them the star of any party.
Make Ahead and Storage
Storing Leftovers
I usually keep leftover cupcakes stored in an airtight container in the refrigerator for up to five days. Just bring them to room temperature before enjoying—I promise, the texture and flavor bounce right back.
Freezing
Freezing works great with these cupcakes. I freeze them unfrosted in a single layer on a baking sheet, then transfer to a freezer bag. When I’m ready, I thaw overnight in the fridge and frost fresh before serving. This keeps the flavors bright and the icing fluffy.
Reheating
If you want to warm a cupcake, I pop it in the microwave for just 10-15 seconds—don’t overheat or the frosting may start to melt. For a fresh-out-of-the-oven feel, let it come to room temp after reheating for best texture.
Frequently Asked Questions:
Absolutely! You can substitute the buttermilk with a dairy-free milk mixed with a tablespoon of lemon juice or vinegar, and use a dairy-free butter alternative for the frosting. Just make sure your marshmallow fluff is also vegan-friendly if needed.
The addition of hot cocoa mix along with cocoa powder adds a unique, sweeter chocolate flavor that’s reminiscent of a warm cup of hot chocolate—making these cupcakes especially comforting and indulgent.
Make sure your cupcakes are completely cool before frosting. Also, keep assembled cupcakes in a cool room or refrigerated to maintain the frosting’s texture and prevent melting.
Yes! Simply pour the batter into a greased and floured 9x13-inch cake pan and bake for about 30–35 minutes. The frosting applies just as beautifully on cake layers as on cupcakes.
