The Best Chocolate Birthday Cupcakes with Fudgy Chocolate Buttercream.

The BEST chocolate birthday cupcakes…with fudgy chocolate buttercream!
This is the perfect Friday recipe, right?! Even if it’s not your birthday, we can certainly pretend, because trust me everyone needs a cupcake today. Yep, I’m just feeling like the world could use one or two. Now, I know cupcakes can’t really solve all the problems of the world. But you gotta admit, there’s something pretty wonderful about sitting down with a delicious chocolate buttercream cupcake that seems to melt away the problems of the world…if only temporarily.



As a lot of you already know, my adored little sister, Asher, celebrated a birthday this week. And as is tradition, every year I make a recipe for the blog that is birthday inspired. After all, she is my favorite (and only) little sister.
First Year: Ultimate Triple Layer Chocolate Bourbon Peanut Butter Buckeye Cake
Second Year: Magic Gooey Chocolate Meringue Texas Sheet Cake
Third Year: Chocolate Bourbon Caramel Macaron Cake (this was also my cookbook announcement post)
Fourth Year: Vanilla Birthday Cake with Whipped Chocolate Buttercream
Are you seeing a pattern? Lots and lots of chocolate, Asher’s favorite. Last year’s vanilla birthday cake was a pretty big stretch for me, but I was able to convince her with the whipped chocolate buttercream. She actually ended up loving that cake…and realizing that maybe, just maybe, there might be a few great non-chocolate desserts out there too.


Anyway, in previous years I’ve surprised Asher with a new cake recipe. But I’m going to be honest, most of the time she just ends up asking me to make her a regular chocolate cake. So this year I decided, instead of surprising her with one of my over-the-top cake creations, I would just ask the girl what she wanted.
To be expected she said chocolate cake, but this year she wanted the cake in the form of cupcakes! For some reason, Asher is really having a moment with cupcakes. Can you blame her though? Cupcakes are cute, hand-held, and an all around fun and delicious dessert.
Plus, I personally think cupcakes are small enough that it’s totally acceptable to go back for a second. Obviously.


It’s not very often that I do a super classic recipe like these cupcakes. But every once in a while I like to throw a classic into the mix, because sometimes, you really just cannot beat the classics.
And let’s be real, everyone needs a good chocolate cupcake recipe in their back pocket. It’s kind of a must.
The best part? These Best Chocolate Birthday Cupcakes are SO easy.
I’m talking ONE bowl for the cupcake batter, and ONE bowl for the buttercream. Honestly, these are so simple that the thought of running to the store for a box mix will not even cross your mind. And trust me, these cupcakes are million and one times better than anything out of a box.


The cake itself is incredibly soft, moist, and extra fudgy, with just the right amount of chocolate flavor, and the perfect amount of crumb. As the title states, these cupcakes are the BEST! I know, kind of bold, but these cupcakes have been made one hundred times over now, and they really just cannot be beat.
My little secret to making these cupcakes extra delicious? A couple of handfuls of mini chocolate chips stirred right into the batter.
Yummmm.
And the frosting? Oh, the frosting, it’s basically chocolate buttercream heaven, and the only real way to truly complete these cupcakes.
Also, I feel as though I should mention that everyone I make these cupcakes for likes the ratio of cake to buttercream to be close to one to one. This means my buttercream recipe makes a lot of frosting. I’d say you could downsize the recipe a bit, but then really, would you really want to do that?
I’m thinking not.
While we might not all be celebrating a birthday this week, we are heading into a long holiday weekend. Therefore, I could not think of a better recipe to send you guys off with than these chocolate cupcakes.
Perfect for any and all Labor Day activities!

The Best Chocolate Birthday Cupcakes...with Fudgy Buttercream
By halfbakedharvest
Course: Dessert
Cuisine: American
Keyword: buttercream topping, celebration cake, chocolate cup cakes
Possibly the best chocolate cupcake ever!
Ingredients
- 2 eggs
- 3/4 cup buttermilk
- 1/4 cup plain greek yogurt
- 1/2 cup canola oil
- 1 tablespoon vanilla extract
- 1 1/2 cups all-purpose flour
- 1 1/2 cups granulated sugar
- 1 cup unsweetened cocoa powder
- 1 1/2 teaspoons baking soda
- 1 1/2 teaspoons baking powder
- 1 teaspoon kosher salt
- 1/3 cup hot black coffee
- 1/2 cup mini semi-sweet chocolate chips (optional)
Fudgy Buttercream
- 3 sticks (1 1/2 cups salted butter) at room temperature
- 3 cups powdered sugar
- 3/4 cup unsweetened cocoa powder
- 2 teaspoons vanilla extract
- 3-4 tablespoons heavy whipping cream
Instructions
-
1. Preheat the oven to 350° F. Line 24 muffin tins with paper liners.
2. In a large mixing bowl, beat together the eggs, buttermilk, greek yogurt, canola oil, and vanilla until smooth. Add the flour, sugar, unsweetened cocoa powder, baking soda, baking powder, and salt. Mix until there are no longer any clumps of flour. Add the hot coffee and mix until combined. The batter should be pourable, but not super thin. Stir in the chocolate chips, if using.
3. Pour the batter among the muffin tins and bake 15-18 minutes, until a tester inserted into the center comes out clean. Remove and let cool completely before frosting.
Fudgy Buttercream
-
1. In a large mixing bowl, beat together the butter and powdered sugar until the butter is light and fluffy, about 2 minutes. Add the cocoa powder and vanilla and beat, scraping down the sides as needed another 2 minutes or until there are no streaks of white. Add 3 tablespoons of the heavy cream and whip the frosting for 2-4 minutes or until light and fluffy. If desired add the remaining tablespoon of the heavy cream. Taste the frosting and add more powdered sugar if you like a sweeter or thicker frosting.
2. Frost each cupcake as desired. The cupcakes will keep for 3-4 days in the fridge, bring to room temp before eating.

I really cannot blame her on the cupcake part! You make these cupcakes look so absolutely divine! The frosting looks so delicious.
Thank you, Amanda! I hope you have a great weekend!
OMG, I LOVE the smoke shots! Those photos are really cool! And let’s be honest, I kinda want to face plant into those cupcakes.
Thank you so much, Christina! Have a great weekend! ps. I agree with the face planting. LOL.
These look delicious – is the recipe already altitude adjusted (I’m in Denver), hoping so.
HI! Yes, these work great in the altitude. The centers will sink just slightly, but I love this becasue it allows for a pocket of extra frosting! Let me know if you have questions! 🙂
Perfect recipe going into the holiday weekend–these look beyond amazing. Thanks for the Friday treat Tieghan and happy belated to Asher!
Thanks Erica! Have a great weekend!
I’m allergic to coffee. Can I leave that out of the cupcake batter, or will that ruin the recipe?
HI! Use an equal amount of water in place of the coffee. The cupcakes will be great! Enjoy and let me know if you have other questions. 🙂
These are awesome. I love a good cupcake (especially chocolate), and these look perfect. And you’re such a sweet sister. I think it’s so cute how you do a new recipe for her birthday each year. She is lucky to have you!! 🙂 Have a great long weekend.
Thanks Natasha!
Happy Birthday Asher, what an awesome sister you’ve got!
I will tell her you said happy birthday! THANKS!
I went back to see what I wrote three years ago.
I couldn’t wait for your cookbook to come and I thought you should use your cake picture on the blog because it was so good. Now there will be a studio and even more incredible recipes and pictures to come.
Congrats on three more years and Happy Birthday Asher.
Awe! Thank you so much, nancy! I am beyond flattered! Hope you had a great weekend!

Oh I love it! I bet asher was stoked for the extra chocolate love this year. They look EPIC!
Thanks so much, Lindsay!
Just a quick question – do I need to sift the powdered sugar or is it unsifted? This looks just wonderful and I have a cake to make this week!
HI Debra! No need to shift the powdered sugar. Hope you love the cupcakes!
That frosting looks out of this world! I will be saving these because my kiddo turns two next month and I’ve been thinking about cupcakes!
Yeah! I hope you all love the cupcakes. Thanks Leigh Ann! 🙂
Happy birthday to Asher! What a perfect treat.
Thanks Jennifer!
You really need a like button. Or better yet, a love button because I would be lovin all over your site! Did that sound weird? lol
haha! Not at all! That is such a compliment. Thanks Lisa!
Could u put this batter in a 9 x 13 pan??? I’m out of cupcake liners
Hey Nancy! Yes, baking in a 9×13 inch pan works great. I would bake for 25-30 minutes. Hope you love the cake!
I just love these cupcakes – what a perfect treat to celebrate Asher! 🙂
Thank you! 🙂

While scrolling down this recipe I realized my mouth was watering! Too bad it’s only Monday… I will keep this recipe in the back of my mind until this weekend. Can’t wait!
Haha I am so glad you love this Stine Mari! Thank you!
I made these cupcakes and the frosting. Was amazing. How do I make the frosting go just be white instead of chocolate ? Want to make it again but with vanilla frosting. I’ve never done homemade frosting before.
HI! Just simply omit the cocoa powder from the frosting. should be great! Thrilled you love the cupcakes. Thanks!
Hi there, These look amazing. I want to make for my son’s birthday this weekend. Does this recipe require a mixer or can it all be done by hand? P.S. I pretty much make at least two meals from your site each week. Love it!
Hi! This can be done by hand, that will be great! Let me know if you have other questions. Hope you love this recipe! 🙂
Also, THANK YOU! That makes my day. Hope your son loves the cupcakes!!!
These look amazing! Just wondering if there is anything I might be able to substitute for the coffee?? I can’t have coffee, but would love to make these!
Thanks!
Hey Jessica! You can water in place of the coffee. Please let me know if you have any other questions. I hope you love this recipe. Thanks so much and happy Holidays!! xTieghan ?
Have you done this with Dutch processed cocoa powder? I know it doesn’t react with baking soda so was just curious.
Dutch process cocoa powder will be great! Please let me know if you have any other questions. I hope you love this recipe. Thanks so much!! xTieghan
Would this recipe be enough to make 3 8in round cake layers? And how long would it take to bake? I’d love to make this into a chocolate layer Cale. Sounds delicious!!
Hey Jayme, I would use my 3-layer chocolate cake recipe. It sounds like it is exactly what you are looking for. Link below. Please let me know if you have any other questions. I hope you love this recipe. Thanks so much!! xTieghan

Hey Teighan, I have two cupcake tins but I like one much better. What if I baked them 12 and 12? Would it be okay if half the batter sat while the first batch cooks? If not, I’ll just use both tins. Let me know what you think!
Hi Renee! Yes, baking 12 and 12 will be totally fine! Please let me know if you have any other questions. I hope you love this recipe! Thank you! xTieghan
Can you freeze the baked cupcakes (and even the icing) and assemble the day of? Just trying to make them in the week, and have them ready for the weekend.
thanks!
Hey Laura! Yes, you can freeze both the cupcakes and frosting. I think that should work great! Please let me know if you have any other questions. I hope you love this recipe! Thank you! xTieghan ??
Thanks dear.
Can you please mention the weight of the ingredients in grams and mililitres.
Normally 1 cup equivalent to how much of grams?
Hi there! I am sorry, I am not comfortable converting the recipe to grams as it’s not something I’ve done and I don’t want to miss guide you. Have you tried using an online calculator?
Please let me know if you have any other questions. I hope you love this recipe! Thank you!! xTieghan
I only made half this recipe and it was enough for the 5 star rating. Made these for my son’s birthday party with my own vanilla vanilla butter cream frosting. They didn’t last long! The cake was so moist and rich, but not too rich, and we all loved the add of the chocolate chips. We also made the Ice Cream Cake, and this same cake serves as a base layer – and it is now a family favorite. Thanks.
Hi! I am so glad this turned out so well for you all! Happy Birthday to your son! xTieghan
Would this recipe work with two 8 inch cake pans?
Hi Kelli! Yes, it will work! I hope you love this! xTieghan
Hi! I want to make these for my nephews birthday but no buttermilk at the store, what can I use as a replacement?? Thank you!!
Hi Carolyn! I would use regular milk with a little under a tablespoon of lemon juice. Let it sit for 5 minutes before using! Please let me know if you have any other questions! xTieghan
So excited to make these for a bridal shower this weekend. Can I substitute coconut oil for the canola oil? Thanks!
Hi Kristen,
Yes that will work! I hope you love the recipe, please let me know if you have any other questions! xTieghan
I love all your post and I want to try your chocolate cake
I hope you do try it! Thank you so much Thina! xTieghan
I made these today and honestly, they are the best cupcakes I have ever made. The batter was bananas! During Covid I have made a lot of your recipes and each one is delicious and easy and exactly as described. Thank you so much!
Aw that is so great to hear! I hope you continue to love this and other recipes of mine, Elissa! Thank you! xTieghan
Hi,
Can I use peanut/vegetable oil instead of canola oil? If not which other oil can I use
Thanks
Hey Deepti,
Yes vegetable oil is totally fine to use. I hope you love the recipe, please let me know if you have any other questions! xTieghan
I was just wondering can you taste the coffee in the cupcakes because I am making them for a friend and she likes coffee and I don’t but I want everyone to be able to enjoy them?
Hey Hannah,
You cannot taste the coffee, it just enhances the chocolate flavor. I hope you love the recipe, please let me know if you have any other questions! xTieghan
I really dislike coffee. Do you taste it at all in the finished product?
Hey Sarah,
You cannot taste the coffee, it just enhances the chocolate flavor. I hope you love the recipe, please let me know if you have any other questions! xTieghan
I made these for my friend for her 50th birthday and she loves chocolate cupcakes. She said these were the best she’s ever had! I have to agree. Love, love, love!!!
Thank you so much Crista!! xTieghan
What an amazing recipe! Is perfect! It was very easy to make and the result is incredible. Everybody loved them. I’m pretty sure I’ll be coming back again to this recipe!
Hi Adri! I am really glad you all enjoyed this recipe! Thank you so much for trying it!! xTieghan
I loved this cupcake recipe
Thanks so much Amanda!
this recipe is really perfect for a birthday and the cupcakes are very versatile, it works on any occasion
Hey Bia,
I am thrilled you enjoyed the recipe. Thanks for giving it a try! xTieghan
I love cupcakes and this recipe seems to be very tasty.
Thanks so much!
Hi! SO excited to make these for my son’s birthday! Something to look forward to for a pandemic birthday 🙂 How would you translate this into mini cupcakes? Thank you!
Hey Caity,
How fun!! I would follow the recipe as is but obviously reduce your bake time. Depending on the size of the mini cupcakes you may want to starting checking for doneness at 15 minutes. I hope you love the recipe, happy birthday to your son! xTieghan
Going to make these this week! Wondering though, I can’t really eat yogurt – is it possible to replace that with something else like coconut milk maybe? Thanks!
Hey Marissa,
You can use sour cream in place of the yogurt. I hope you love the recipe, please let me know if you have any other questions! xTieghan
