Some of my most joyful moments in the kitchen involve making buttercream frosting. The fluffier, the better – that’s my motto.
It’s not only fun for me to make and eat myself, but I also immensely enjoy the reactions from those I love when that first swipe of fluffiness reaches their lips. Really great buttercreams are not an everyday occurrence. They’re special, and should be totally and completely enjoyed without guilt. That’s another motto of mine.

Today is our sweet Tessa’s birthday. She is now 11 years old.
We’ve been celebrating the past few days, first with a handful of girlfriends and a sleepover on Friday night, and then with my parents here for the weekend. The best celebrations always involve our besties in life.
When all you want is fluffy marshmallow frosting…
When I asked Tessa what she’d like me to make for her birthday treat this year, she replied, “I don’t care what kind of cake, but I’d like marshmallow frosting.” Oh, how I love this girl!
I knew in my heart that this fluffy marshmallow buttercream was a success once I finished capping all the chocolate cupcakes with big pillowy mounds of frosting. It was delicious. And it looked so fun!
Tessa took one look and her eyes got big and wide. “For me?!”
She wholeheartedly approved these chocolate cupcakes, saying how fun they looked and how great they tasted. The marshmallow buttercream got highest marks. One of Tessa’s girlfriends even tried to commission me to make these for her birthday party in a few months. :)
How to make fluffy buttercream frosting:
1. Start with room temperature butter by taking it out of the refrigerator in plenty of time to completely soften on its own. Do NOT soften your butter in the microwave, as this tends to soften it unevenly.
2. Whip the butter. Alot! I start out by whipping the butter alone…for a full 8 minutes in my stand mixer with the paddle attachment. You might think that sounds crazy to whip the butter for that long, but just trust me. A longer whipping time allows more air to be incorporated, and you will see the butter lighten in both color and texture.
3. Beat in the powdered sugar, a bit of salt, some half and half or heavy cream, and any flavorings.
4. To add color to your buttercream, I recommend gel colors. Gels have less liquid and more pigment than liquid colorings, which means you can use less and won’t risk diluting the frosting with excess liquid. I’m a total fan of gel colors.
5. Now whip it all again! For this final step, I set the timer for 5 minutes and walk away, only returning once or twice during this time to scrape down the bowl.
Use a scoop to decorate this chocolate cupcake
Have you ever used a scoop to add frosting to cupcakes? It’s one of my favorite methods!
You will want to seek out a large scoop that has a big diameter. I like this 4-tablespoon scoop that allows a small perimeter of cake to remain visible in this standard sized cupcake.
(Those brown paper liners are my go-to liners for cupcakes and muffins.)
The scoop method for applying the fluffy marshmallow buttercream pronounces the fluffiness of this frosting. It enables the frosting to sit nice and tall, with very little effort. It’s so easy!
To finish these off, I simply sprinkled the frosted tops with shavings from a chocolate bar.
No-fail chocolate cupcake recipe for celebrating
I know that so many people feel intimidated to make their own cupcakes for celebrations, afraid they won’t be able to produce treats that look and feel special enough.
But I beg you to let go of those belittling feelings and just give this recipe a try. You’ll be surprised at the results of this easy-to-make chocolate cupcake recipe, and even find a little joy in the process.

Chocolate Cupcakes with Fluffy Marshmallow Buttercream
Ingredients
for the chocolate cupcakes:
- 3 c. all-purpose flour
- 6 T. cocoa powder
- 1 tsp. kosher salt
- 2 c. sugar
- 1 T. espresso powder
- 2 tsp. baking soda
- ⅔ c. vegetable oil
- 2 T. vinegar
- 2 c. cold water
- 1 T. pure vanilla extract
for the fluffy marshmallow buttercream:
- 2 c. unsalted butter at room temperature
- 5 c. powdered sugar
- ½ tsp. kosher salt
- 2 T. half and half
- 1 T. pure vanilla extract
- 1 13 oz. container marshmallow creme (use a new container, so it’s fresh and ultra fluffy)
- chocolate shavings
Instructions
- for the chocolate cupcakes: Preheat oven to 350° F. Line 2 regular size cupcake pans with 24 paper liners and set aside.
- In a large bowl, whisk all dry ingredients to combine. Make 3 large holes in the dry ingredients.
- In a separate smaller bowl, combine oil and vinegar. Pour this into the 3 holes of the dry ingredients. Pour the water over entire mixture. Mix with a fork. Add vanilla and stir.
- Divide batter evenly amongst the 24 cupcake wells. Bake for about 25 minutes, or just until a toothpick comes out clean. Remove cupcakes to wire rack to cool completely.
- for the fluffy marshmallow buttercream: In the bowl of a stand mixer fitted with a paddle attachment, whip butter on medium-high speed until very fluffy, about 8 minutes, occasionally scraping down the sides and bottom of the bowl. Add powdered sugar and salt, and beat on low to incorporate. Add half and half and vanilla extract, mixing on low until combined. Increase mixer speed to medium-high and beat until very light and fluffy, about 5 minutes, occasionally scraping down the sides and bottom of the bowl. Then add marshmallow creme and mix on medium speed until just combined.
- to assemble cupcakes: Use a large 4-tablespoon scoop to top each cupcake with a round of marshmallow buttercream. Gently tap the bottom of the cupcake on the counter once or twice to settle the buttercream onto the cupcake. The marshmallow buttercream recipe makes enough frosting for 24 cupcakes frosted in this generous manner. Top the marshmallow buttercream with a sprinkling of chocolate shavings.
This Cake Mix is Awesome! I needed an Allergy Safe Mix for 850 kids. It turned out perfect every time, I used it without the frosting; cake taste was amazing. no one could tell anything was ‘different’. I used Gerbs Cocoa Powder and King Arthur help line recommended to replace 1/4 cup of water with coffee because their espresso powder (or any other brand) was not totally safe for Tree Nut allergy. It made a perfect bottom for out a Toy Story bottom!
Yay!! I’m so happy to hear this. Thanks Vicki!
Can you do piping with this marshmallow frosting recipe?
I’ve read and reread the instructions…when is the marshmallow fluff added to the frosting?
Hi Candace – look in the instructions under “for the fluffy marshmallow buttercream:”, in the last sentence.
I’ve been searching for a marshmallow butter cream for my daughter’s s’mores birthday cake request. Will this spread well for a layer cake?
Hello Jamie – Although I have not tested this buttercream on a layer cake, I do believe it would work well.
I am wondering if these could work as mini cupcakes and if so how would the baking time differ? I can’t wait to make them!
Hello Alissa – this recipe would definitely work for mini cupcakes. I haven’t tested minis for bake time, and quite candidly, mini cupcake measurements vary so much. I would just cut back the bake time and pay close attention, periodically testing for doneness with a toothpick. They will definitely bake up quicker than a full size cupcake. I hope you like these – they’re a favorite of our youngest daughter!
Hi,
I wanted to try to bake 2 8″ round cakes instead of cupcakes. Should I still bake them at 350 degrees? How long do you think that they should bake?
Want to try this recipe for marshmallow frosting. Need to know if it requires refrigeration or can leave frosted cupcakes at room temp?
Hi Brenda, getting ready to make these and notice there are no eggs? Just making sure before I get going on them! Love all your recipes!
Hello Kathleen! That is correct. No eggs. :)
You are speedy! Thank you. This is great news as I have a couple friends who are allergic to eggs, they will be thrilled! But for now it’s to satisfy a bunch of middle schoolers at a book fair! Thanks again!
These look fantastic!! Have you ever made this frosting with coconut extract?
Hello Marina – I have not used coconut extract with this marshmallow buttercream, but I think it would be great. Also check out my recipe for fluffy coconut buttercream here: https://www.afarmgirlsdabbles.com/coconut-cupcakes-with-fluffy-coconut-buttercream-recipe/ Enjoy!
