Why You’ll Love Hot Chocolate Cupcakes with Marshmallow Buttercream Recipe
There’s plenty to love about these adorable hot chocolate-inspired cupcakes. The chocolate cake is soft, moist, and full of cocoa flavor, while the marshmallow buttercream adds a creamy sweetness that complements the chocolate beautifully.
They’re also surprisingly simple to prepare despite their impressive appearance. The cupcake batter comes together with basic baking ingredients, and the frosting requires only a few ingredients.
Best of all, decorating them is part of the fun. Mini marshmallows, chocolate chips, crushed peppermint, and candy canes transform ordinary chocolate cupcakes into charming little mugs of hot cocoa.
Ingredients
(Tip: You’ll find the full list of ingredients and measurements in the recipe card below.)
For the Chocolate Cupcakes
- 2 cups all-purpose flour
- 2 cups granulated sugar
- 1/2 cup unsweetened cocoa powder
- 1/2 teaspoon salt
- 2 teaspoons baking soda
- 1 teaspoon baking powder
- 1 teaspoon vanilla extract
- 2 large eggs
- 1 cup buttermilk
- 1 cup vegetable oil
- 1 cup hot water
For the Marshmallow Buttercream
- 3/4 cup unsalted butter, softened
- 1 container (7 ounces) marshmallow creme
- 1 cup powdered sugar
- 1 teaspoon vanilla extract
For Decorating
- Mini candy canes
- Mini marshmallows
- Chocolate chips
- Crushed candy canes
Directions
1. Prepare the Oven and Cupcake Pans
Preheat the oven to 350°F (175°C). Line two standard muffin pans with cupcake liners and set them aside while you prepare the batter.
2. Combine the Dry Ingredients
Add the all-purpose flour, granulated sugar, cocoa powder, salt, baking soda, and baking powder to a large mixing bowl. Stir or whisk until the ingredients are evenly combined and there are no obvious lumps of cocoa.
3. Add the Wet Ingredients
Add the vanilla extract, eggs, buttermilk, and vegetable oil to the dry ingredients. Mix until you have a smooth, evenly combined chocolate batter.
Gradually pour in the hot water and continue mixing until incorporated. The finished batter will be quite thin, which is normal for this recipe.
4. Fill the Cupcake Liners
Divide the chocolate batter among the prepared cupcake liners, filling each approximately two-thirds full. Avoid overfilling because the cupcakes need room to rise.
5. Bake
Bake for approximately 16 to 18 minutes. Check for doneness by inserting a toothpick into the center of a cupcake. It should come out clean or with just a few moist crumbs attached.
Remove the cupcakes from the oven and allow them to cool briefly in the pans before transferring them to a wire rack. Let them cool completely before adding the buttercream.
6. Make the Marshmallow Buttercream
Place the softened unsalted butter in a large mixing bowl. Using an electric mixer, beat the butter until creamy and smooth.
Add the marshmallow creme and continue beating until thoroughly combined.
Add the powdered sugar and vanilla extract. Beat again until the frosting becomes smooth, creamy, and fluffy. Scrape down the sides of the bowl as necessary so everything is incorporated evenly.
7. Frost the Cupcakes
Once the cupcakes have completely cooled, spread or pipe the marshmallow buttercream over each cupcake.
If you want tall, decorative swirls of buttercream, consider preparing extra frosting so you have plenty for generous piping.
8. Decorate
Sprinkle mini marshmallows, chocolate chips, and crushed candy canes over the frosting.
For the signature hot-chocolate-mug appearance, carefully trim mini candy canes to an appropriate size and insert the curved portion into the side near the top of each cupcake. The candy cane should resemble the handle of a tiny mug.
Serve soon after decorating for the best presentation.
Servings and timing
This recipe makes approximately 28 standard-size cupcakes.
Preparation time: 20 minutes
Baking time: 16–18 minutes
Total time: approximately 38 minutes, plus cooling and decorating time
Oven temperature: 350°F (175°C)
For the best results, allow enough additional time for the cupcakes to cool completely before frosting. Applying marshmallow buttercream while the cakes are still warm can cause the frosting to soften or melt.
Variations
Peppermint Hot Chocolate Cupcakes
Add a small amount of peppermint extract to the frosting for a stronger peppermint flavor. Peppermint extract is potent, so start with just a little and adjust according to taste.
Mocha Cupcakes
Replace the hot water in the chocolate cupcake batter with hot brewed coffee. Coffee can intensify the cocoa flavor while adding a subtle mocha note.
Extra Chocolate Version
Add mini chocolate chips to the cupcake batter or sprinkle additional chocolate curls over the finished frosting.
Mini Hot Chocolate Cupcakes
Prepare the batter in mini muffin pans instead of standard cupcake pans. Because smaller cupcakes bake more quickly, begin checking them well before the standard baking time.
Classic Marshmallow Cupcakes
Skip the candy canes and crushed peppermint. Decorate the marshmallow buttercream with mini marshmallows and chocolate shavings for a version you can serve throughout the year.
Holiday Sprinkle Cupcakes
Replace or supplement the crushed candy canes with festive sprinkles. Red, green, white, or silver decorations work especially well for Christmas.
Salted Chocolate Cupcakes
Finish each cupcake with a very small pinch of flaky sea salt. The salt creates a pleasant contrast with the sweet marshmallow frosting and rich chocolate cake.
Storage/Reheating
Store frosted cupcakes in an airtight container to keep them soft and prevent the buttercream from drying out. Because the frosting contains butter, keeping the cupcakes in a cool environment is best.
For short-term storage, the cupcakes can be kept in an airtight container for about 1 to 2 days in a cool room. For longer storage, refrigerate them for up to 4 days.
If refrigerated, bring the cupcakes to room temperature before serving. This allows the cake to soften and the buttercream to regain its creamy texture.
The unfrosted chocolate cupcakes can also be frozen. Once completely cooled, place them in a freezer-safe container or wrap them individually before freezing. They can be frozen for up to 2 to 3 months. Thaw them at room temperature before frosting and decorating.
For the neatest presentation, add candy canes, crushed peppermint, and mini marshmallows shortly before serving. Candy decorations can become sticky or soften when exposed to moisture for extended periods.
Reheating isn’t necessary. These cupcakes are best served at room temperature rather than warm, especially once they have been frosted.
FAQs
1. Why is my chocolate cupcake batter so thin?
A thin batter is expected with this recipe because it contains hot water and a generous amount of liquid ingredients. Don’t add extra flour simply to thicken it. The liquid batter helps create cupcakes with a soft, moist texture.
2. Can I make these cupcakes ahead of time?
Yes. You can bake the chocolate cupcakes a day or two ahead and store them in an airtight container once completely cooled. For the freshest appearance, frost and decorate them closer to serving time.
3. Can I freeze Hot Chocolate Cupcakes?
The unfrosted cupcakes freeze very well. Allow them to cool completely before placing them in a freezer-safe container. Thaw them at room temperature before adding the marshmallow buttercream and decorations.
4. Can I make the marshmallow buttercream ahead of time?
Yes. Prepare the buttercream in advance and keep it covered in the refrigerator. Before decorating the cupcakes, let the frosting soften at room temperature and whip it briefly with an electric mixer to restore its light, creamy consistency.
5. Why do the cupcakes need to cool before frosting?
Warm cupcakes can melt butter-based frosting. Even slightly warm cupcakes may cause the marshmallow buttercream to soften, slide, or lose its shape. Wait until the cupcakes have cooled completely before decorating.
6. Can I use regular milk instead of buttermilk?
Buttermilk is recommended because its acidity and texture contribute to tender chocolate cupcakes. If you don’t have buttermilk, you can prepare a substitute by combining milk with a small amount of lemon juice or white vinegar and allowing it to sit briefly before using.
7. Can I leave out the candy canes?
Absolutely. The candy canes are mainly decorative and add peppermint flavor. You can leave them off and simply decorate the cupcakes with marshmallows, chocolate chips, chocolate shavings, or sprinkles.
8. How do I know when the cupcakes are finished baking?
Insert a toothpick into the center of one of the cupcakes. If it comes out clean or with a few moist crumbs, they’re ready. If wet batter remains on the toothpick, continue baking for another minute or two before checking again.
9. Can I pipe the marshmallow buttercream?
Yes. The marshmallow buttercream can be piped onto completely cooled cupcakes. If you’re planning large, decorative swirls, making extra frosting is useful because piped decorations generally require more buttercream than simply spreading frosting over the cupcakes.
10. How can I keep the candy cane decorations from getting sticky?
Add the candy cane decorations as close to serving time as practical. Peppermint candies can absorb moisture from frosting and the surrounding air, causing them to become sticky or begin dissolving. Storing the cupcakes in a cool, dry place and adding the candy decorations later helps maintain their appearance.
