This moist chocolate cupcake recipe with creamy chocolate buttercream. Pair it with fudge frosting for a chocolate lover, strawberry buttercream for a springtime dessert, or cream cheese frosting for a perfect birthday treat.
These homemade cupcakes are similar to my famous easy chocolate cake recipe and easy buttercream frosting, but even easier to make! Even my daughter, Avalon, could make these cupcakes at 5 years old.
The secret to super moist and flavorful chocolate cupcakes is a little espresso powder that brings out the flavor in chocolate! I often use coffee in my chocolate cake recipes, like my death by chocolate cake, for the same reasons.

Chocolate Cupcake Ingredients
Oil – Cocoa powder is very drying so to make your chocolate cupcakes moist, you will need oil. Some recipes use butter (like mine) for added flavor and texture but oil really helps create moist cupcakes.
Warm Buttermilk – Not only does the warm buttermilk help bloom the cocoa powder, it also makes the cupcakes super tender and moist.
Espresso powder - This is an optional ingredient, but helps make them delicious. It doesn't make your cupcakes taste like coffee, it just enhances the flavor of the chocolate. I use hot coffee in my chocolate cake recipe, so it has a similar effect without adding extra liquid.
Brown Sugar - Did you know that white sugar is just brown sugar with the moisture removed? It adds a depth of flavor that is delicious, just make sure to sift it to remove any hard lumps. That moisture is called molasses. If you want to add moisture to a recipe, replace half the white sugar with brown sugar.
Cocoa powder - Really any kind of cocoa powder will work for these cupcakes. You can also use dutch-process cocoa powder for a darker color and more intense flavor, or natural cocoa powder for a more milk chocolate flavor.
Making Chocolate Cupcakes
- Preheat your oven to 350ºF and prepare your cupcake pan with paper liners.
- For the best results, warm the buttermilk in the microwave (roughly 100ºF), and warm the eggs in hot water for 5 minutes. Warm ingredients will create an emulsion and a smoother batter.
- Combine the buttermilk, oil, and vanilla together and set it aside.
- Whisk together the flour, cocoa powder, baking soda, baking powder, salt, and espresso powder in a mixing bowl and set it aside.
- Cream together the butter, white sugar and sifted brown sugar in your stand mixer with the paddle attachment until light and fluffy. If you don't have a stand mixer, you can use the whisk attachment and a hand mixer, but I would mix the rest of the ingredients by hand to avoid overmixing.
- Add in the eggs one at a time while mixing on low, letting the first one mix in before adding the second. Scrape the bowl to be sure that everything is mixed well.
- While mixing on low speed, add ⅓ of the dry ingredients, followed by ⅓ of the wet ingredients. Alternate two more times until just combined.
- Fill your cupcake liners ½ of the way full. This recipe makes about 24 cupcakes.
- Bake the cupcakes at 350°F for 18-20 minutes until set. Do not overbake.
- Cool completely on a cooling rack before frosting.
Making Chocolate Buttercream
- Cream the butter until smooth.
- Then add in the melted chocolate and cream until smooth.
- Mix in the powdered sugar, vanilla, salt, and the heavy cream and cream until smooth.
- Add more cream if the frosting seems too thick.
FAQ
Oil is important for making moist chocolate cupcakes, but too much oil in a recipe will cause the wrappers to peel away from the cupcake. Some people add sour cream for moisture, but I prefer buttermilk for that moisture and acidity.
If you want to make sure your cupcakes are very fluffy, you want to cream the butter and sugar together really well. I have had a lot of really delicious cupcake recipes that come together in one bowl with no creaming required but the texture is fudgy rather than fluffy.
I used to think it was a problem with the recipe that I was using but the secret to a perfectly domed cupcake is actually how full you fill the cupcake liner. You only need to fill the cupcake liner ½ to ⅔ full. If you over-fill then your batter will rise up and then collapse over the edge.
You can use a medium cookie scoop to get your batter in your liners or you can even put your pan on a scale and pipe your batter into the liners for the ultimate accuracy!

Notes
- Make sure all your ingredients are at room temperature before mixing your batter (milk, butter, eggs).
- Use good quality vanilla extract, vanilla bean paste, or even a vanilla bean for true vanilla flavor. One vanilla bean = 2 teaspoons vanilla extract.
- Preheat your oven to 350ºF for 30 minutes before baking to give your cupcakes a good rise and set the dome.
- Baked cupcakes can be frozen for up to 6 months.
- Buttermilk is essential to this recipe because it adds flavor and moisture. If you have whole milk and white vinegar or lemons, you can make your own buttermilk substitute.
- If you don't have a paddle attachment, mix by hand with a spatula to avoid overmixing.
Anisha Thomas says
Hey love thanks for the recipe but do u use low fat buttermilk or whole because I can't find while buttermilk anywhere!
The Sugar Geek Show says
I don't think it matters as long as it's buttermilk
Kaitlyn Middleton says
Can you use instant coffee instead of espresso powder?
The Sugar Geek Show says
I'm not sure it would work exactly the same https://www.kingarthurflour.com/blog/2017/01/16/baking-with-espresso-powder
Blossom says
Baking a cake for my niece for her bday but she is allergic to raw egg. whats the replacement for egg white in the chocolate buttercream. Please can u suggest. Thank u ?
The Sugar Geek Show says
There isn't a replacement for this recipe, you could make chocolate ganache or you could make American buttercream and add in 1/4 cup sifted cocoa powder

Best Chocolate Cupcakes...EVER. All of the other chocolate cupcake recipes I've tried have had such a sticky texture, but not these, which is EXACTLY what I was looking for. So light and fluffy, it was the perfect bakery cupcake. Your vanilla cupcakes were awesome, so I knew these would be too. Thanks so much!!!!!
Mary says
I LOVE these cupcakes! Best chocolate cupcakes ever!! I often get orders for a dozen, can I easily half this recipe and be safe?
Thanks!!!
The Sugar Geek Show says
Yes you can, or you can freeze leftover cupcakes in freezer-proof containers for up to 6 months
Mary says
Oh, freezing them would be nice so they are on hand! Do you need to wrap the cupcakes individually in plastic wrap or anything to keep them moist? And how/when do you need to thaw them for use?
The Sugar Geek Show says
I would wrap individually in plastic wrap and then into a freezer bag. No need to defrost in a certain way. Just take them out of the bag and leave at room temperature.
Angie says
These cupcakes are so so good. Truly the BEST chocolate cupcakes ever. Thank you Liz.
Shelly O says

Do you mean for the buttercream? You can only use pasteurized egg whites for this recipe, not raw egg whites.
Sohail says

Yes you can double the recipe
Maryam says
If I need to use this recipe to bake a cake how long should I bake it?
Sugar Geek Show says
I would recommend using my easy chocolate cake or death by chocolate cake recipe instead 🙂
Carrington Brown says
Can I use this recipe as a cake?
Sugar Geek Show says
It's very similar to my easy chocolate cake, so I'd use that recipe instead 🙂 Or check out my death by chocolate cake
Dominic says
These were incredible! For years I'd used an old one bowl recipe from Martha Stewart, but lately had found it to create sunken cupcakes almost half the time. I ended up shopping around and still wasn't quite satisfied. I tried yours and will not be looking anywhere else. It's easy to put together and creates such a fudgy and soft cupcake without the common crisp tops or sunken centers. Thanks Liz!
Genevieve Peterson says
Wow! I made these for my husband's work team. He and I ate a couple of cupcakes before I delivered them to his work . . . you know, to test and make sure everything turned out well. Oh my gosh, we almost decided to keep them all at home! They are so good! I went over the top and filled the cupcakes with fudge and iced them with vanilla buttercream. But the chocolate cake part itself really, ahem, takes the cake. I even had them refrigerated and they were still moist and yummy. I'll be baking those again soon. 🙂 Thank you so much for sharing this recipe.
