These cupcakes are seriously the BEST Chocolate Cupcakes you’ll ever try!
I love to utilize Baking Science to tweak and test recipes until I think they’re the ULTIMATE version of that recipe.
I’ve done it with my ultra-fudgy Ultimate Brownies, my perfectly chewy Ultimate Chocolate Chip Cookies, and my heavenly Ultimate Classic Cheesecake. What better recipe to perfect next than Chocolate Cupcakes?!
Free Baking Science Mini-Course!
From cookies that spread to undercooked brownies, this FREE 5-day Baking Science course helps you conquer common baking challenges and make bakery-worthy treats every time.
It took about 5 straight batches over a couple days, after previous casual tests over several months, to finally nail the recipe.
These cupcakes are perfectly moist and tender. They’re sturdy enough to hold up to plenty of frosting, with TONS of chocolate flavor. There are three kinds of chocolate in here in total!

How to Make the BEST Chocolate Cupcakes
The Chocolate
We can’t make stellar homemade Chocolate Cupcakes without first considering the chocolate! The cupcakes themselves use a whole 5 ounces of bittersweet chocolate AND Dutch-process cocoa powder, for as much chocolate flavor as possible.
Make sure to use freshly chopped baking chocolate and not chocolate chips, which don’t melt down as smoothly. Learn more about Chocolate in Baking here.
Do I Have to Use Dutch Process Cocoa Powder?
I recommend sticking with Dutch-process cocoa as it works differently on a chemical level compared to natural cocoa. You can find it at many gourmet food stores or online via Amazon.
Dutch Process Cocoa typically contains more cocoa butter (fat!) than your typical grocery store cocoa powder. This means more moisture, richness, and rich chocolate flavor! Learn more about cocoa powder’s fat content here.
Help! I Only Have Natural Cocoa Powder!
If you must use regular unsweetened cocoa powder in this recipe, then omit the vinegar – just note that your cupcakes may be a little more dry. Learn more about the differences between cocoa powders here.
The Secret to Super MOIST Chocolate Cupcakes
- This recipe calls for vegetable oil instead of butter. This creates an ultra-moist texture and an open, slightly spongy crumb. For more details on how these two fats work in baking, check out my Butter vs. Oil in Baking article.
- Since oil is liquid at room temperature, it leaves a sensation of moistness on the palate.
- Be sure to also use full-fat ingredients and don’t reduce the sugar in this recipe. Sugar actually helps contribute to moistness! Learn more about the role sugar plays in baking here.
- Be sure to measure your flour and cocoa powder correctly. Use a digital kitchen scale, or the spoon and level method if you don’t have a scale.
Hot Water and Espresso Powder in Chocolate Cupcakes
- If you bake chocolate cakes or cupcakes a lot, you’ve probably seen quite a few recipes that utilize hot water, or even hot coffee.
- This helps to dissolve and ‘bloom’ the cocoa powder to bring out as much flavor with as few cocoa lumps as possible.
- The espresso simply enhances the chocolate flavor without actually being perceptible.
Do I Have to Use Espresso Powder?
Feel free to use hot coffee in place of the hot water and espresso powder. Instant coffee and water will also work. If preferred, simply omit the espresso powder – no modifications needed.
The Eggs
The more whole eggs a cake recipe has, the richer it’ll be. I used one of my favorite baking tricks and added an extra egg yolk. This works beautifully for brownies and cookies, so why not chocolate cupcakes? It adds more richness, chewiness, and structure so the cupcake can stand up to a generous or heavy frosting.
Be sure to use large eggs – about 56 grams in shell. Don’t use eggs larger or smaller than this, as this will impact your cupcakes.
Egg Substitute For Chocolate Cupcakes?
I have yet to find an amazing egg substitute for this recipe. I recently experimented with egg substitutes in cookies, but I haven’t found any great substitutes in cupcakes yet. Let me know in the comments below if you experiment with that!
The Leavener
After much experimentation, I chose to use baking soda, so I had to add vinegar to the recipe. Why? Because without it, there wasn’t enough acid for the baking soda to react with. Dutch-process cocoa powder has been neutralized of its acid, so it was only the sour cream and the small amount of brown sugar.
For tall, tender, light cupcakes, we need the right amount of leavening, so baking soda + vinegar does the trick. This is why you omit the vinegar if you’re using natural cocoa powder.
The Flour
After testing all-purpose vs. bread flour, I found that all-purpose worked just as well. Since AP flour is more readily available, I stuck with that to make this recipe as simple as possible.
Sour Cream in Chocolate Cupcakes?
I find that sour cream adds such a lovely richness and balance of flavor to Chocolate Cupcakes. Full-fat plain yogurt makes a good alternative if needed.
The Chocolate Buttercream Frosting
When I originally published this recipe, it used a more complicated Chocolate Swiss Meringue Buttercream as the frosting. Although delicious, it’s more advanced and requires more time and special equipment.
In the interest of making this recipe simpler but still delicious, I swapped in a special version of American-style chocolate buttercream.
The frosting contains cooled chocolate ganache for pure chocolate flavor and fudgy richness. I like to use semisweet chocolate, but feel free to use milk or bittersweet chocolate instead.
For an extra smooth, flavorful, rich frosting, opt for organic powdered sugar and high-fat cocoa powder.
My Favorite Cupcake Tools:
- Cupcake liners: These cupcake liners are my favorite for cupcakes that don’t stick to the liner.
- Piping tip: I used the Ateco #828 piping tip for swirling the chocolate frosting on these cupcakes – but any large open star tip will work.
- Piping bags: I love these disposable piping bags.

How to Store Chocolate Cupcakes
Complately cooled Chocolate Cupcakes can be stored inside an airtight container at room temperature for up to 1 day.
Can You Freeze Chocolate Cupcakes?
- If storing for longer than a week, wrap unfrosted cupcakes individually in plastic wrap, to prevent freezer burn and taste transference.
- Place cupcakes inside a freezer bag on a shelf in your freezer where they won’t get smashed.
- Freeze for up to 3 months.
- Unwrap the cupcakes and allow them to defrost at room temperature for about 1 to 2 hours.

Ingredients
For the cupcakes:
- 5 ounces (142 grams) bittersweet baking chocolate, finely chopped
- 1/3 cup (28 grams) Dutch-process cocoa
- 1 teaspoon instant espresso powder
- 1/2 cup (118 grams) boiling water
- 3/4 cup (95 grams) all-purpose flour
- 1/2 cup (100 grams) granulated sugar
- 1/2 cup (100 grams) packed light brown sugar
- 1/2 teaspoon fine sea salt
- 1/2 teaspoon baking soda
- 1/2 cup (113 grams) sour cream (or plain full-fat yogurt), at room temperature
- 1/4 cup (56 grams) vegetable oil
- 2 large eggs plus one egg yolk, at room temperature
- 2 teaspoons white vinegar
- 1 teaspoon vanilla extract
For the frosting:
- 1/2 cup (119 grams) cold heavy whipping cream
- 4 ounces (113 grams) finely chopped semisweet chocolate (don't use chocolate chips)
- 3 sticks (340 grams) unsalted butter, at a cool room temperature
- 2 cups (250 grams) powdered sugar, sifted (preferably organic*)
- 1 cup (85 grams) Dutch-process cocoa powder, sifted
- 2 teaspoons vanilla extract
- 1/4 teaspoon fine sea salt
Instructions
Make the cupcakes:
- In a medium heatproof bowl, combine the chocolate, cocoa powder, and espresso powder. Pour hot water over mixture. Cover and let stand for 5 minutes. Whisk mixture gently until smooth, then set aside to cool.
- Meanwhile, preheat oven to 350°F. Line a standard 12-cup muffin tin with paper liners.
- In a small bowl, whisk together the flour, sugars, salt, and baking soda.
- Whisk sour cream, oil, eggs, egg yolk, vinegar, and vanilla into the cooled chocolate mixture until smooth, scraping down the sides and bottom of the bowl as you mix. Stir in the flour mixture until smooth, being careful not to overmix.
- Using a spring-loaded scoop, divide the batter evenly among prepared muffin cups until 3/4 full. Bake until cupcakes are set and firm to the touch, about 17 to 18 minutes.
- Let cupcakes cool in pan on a wire rack for 10 minutes before removing from pan to cool completely, about 1 hour. Cupcakes can be stored in an airtight container at room temperature for up to 1 day.
Make the frosting:
- In a small saucepan, bring the cream to a simmer. Remove from heat and add the chopped chocolate. Let stand for a few minutes before stirring until smooth. Set aside and cool to approximately 75°F or until thickened but still pourable.
- In the bowl of a stand mixer fitted with the paddle attachment, add the butter, powdered sugar, cocoa, vanilla, and salt. Mix on low speed until well blended and then increase the speed to medium and beat for another 3 minutes, or until very well blended, scraping down the bowl as needed.
- Reduce speed to medium-low and add the cooled chocolate cream mixture. Continue beating until the frosting has lightened in color and texture, about 2 minutes more, scraping down the bowl as needed.
- Frosting can be made 1 day ahead of time and stored in an airtight container in the refrigerator. Warm frosting in the microwave for 5 to 10 seconds and stir until creamy again before frosting cupcakes.
- Frosting can also be transferred to a ziptop bag and frozen for up to 1 month. Defrost in the fridge overnight then rewhip in the stand mixer until light and smooth.

What bittersweet chocolate did you use? I can’t seem to see that anywhere. Making for a grad party.
Hi there! Tessa uses Ghirardelli Bittersweet chocolate! Most supermarkets should carry it, and Target typically sells it, too 🙂
Thank you. I don’t live in the US so I used 55%Lindt and they turned out and were very good. Thank you for the reply.
Wonderful!! So happy to hear that!!
This recipe is so amazing! Unfortunately, I’ve recently developed a wheat allergy, but I love this recipe so much, so I tried making the recipe again using Bobs Red Mill 1:1 GF Baking flour and they turned out so great and were super delicious. Thank you!
I’m glad that substitute worked for you, Mandy! 🙂
My goodness this recipe is perfection! The batter tasted great straight out of the oven, was incredible after it was topped with icing, and it was still amazing 3 days later! Both kids and adults loved them!!! Thank you for this amazing recipe it made me look like a pro baker!
Hi Bobbie! SO thrilled that you loved this recipe so much! We love that it made you feel like a pro baker!! Happy baking 🙂
Emily hi
If I don’t have Dutch process cocoa how can I substitute?
Ailyn
Hi Ailyn! Tessa actually explains what to do if you don’t have Dutch process cocoa in the pink box above the recipe 🙂 Enjoy your cupcakes!
Do you happen to know how much batter is best to put in a standard sized tin? Oftentimes with chocolate cupcakes they rise excessively and I have overflow. I use 1/4 c batter with cupcake recipes but your recommendation is to fill them higher than I typically would.
Hi Jennifer! 3/4 full rose up beautifully for us, but when you’re not sure about how much batter is best, we recommend testing it out. Bake two cupcakes prior to baking the entire batch, one filled 2/3 full, the other 3/4 full, for the designated time, and see which you prefer. Then you’re not “messing” up an entire batch and can continue with baking. I hope that helps!
How would I make these as mini cupcakes? do I have to change the baking time or temp?
can I make mini cupcakes instead? how would I convert the temp/time for mini cupcakes?
Hi Rina! Sure! Follow the instructions in our article about converting recipes HERE. Let us know what you think of this recipe when you give it a try 🙂
Do you think I could use these as the base for Black Forest Cupcakes? I’ve been looking for a good recipe but I’m picky about chocolate cake and want it to be dark, moist, and delicious. I’m just worried these won’t handle the moistness of a black forest filling. (I’ve never made filled cupcakes or Black Forest cake but my friend requested them for his birthday so I’m trying to figure it out!). Thanks.
Hi Mary! While we haven’t tried that specifically, these cupcakes hold up well to a good amount of buttercream, I’m sure adding a filling will be completely fine 🙂 If you’ve not made filled cupcakes before, just a helpful hint to use an apple corer to remove the center of the cupcakes. It makes the process go so smoothly and quickly! Please let me know if you have any other questions, and let me know how your cupcakes turn out!
Best chocolate cupcakes i have ever made! I tried dozens of recipes over the years, most of them have common ingredients, technics and taste, but these are unique to me. Very delicate crumb, fudgy, but not wet and the taste is an irresistible chocolate flavor. Thank you for the recipe!
So happy to hear how much you love this recipe, Petya!
Hi! I was wondering if it’s possible to make this recipe as a CAKE please? Thank you! 🙂
Hi Nadia! Check out the bottom of the pink tip box that’s listed above this recipe, Tessa links her favorite Best Chocolate Cake recipe as well as a guide on how to convert cupcakes into cake 🙂
Can you use cake flour? Also if you use brewed coffee do you omit any of the boiling water?
We have only tested bread flour and AP flour, so I can’t say for sure! Yes, if you use hot coffee in place of the espresso powder and hot water, you’ll use the exact amount (omiting the hot water). I hope that helps!
should unsweetened chopped chocolate be 4 ounces? recipe ingredient lists as 5ounces. The chocolate cocoa coffee and water mixture was fudgy.
Hi Diane! No, the chocolate amount is correct as written. The mixture will be a bit fudgy and thicken as the ingredients are mixed together and cooled. How did your cupcakes turn out?
I added more boiling water at the end to loosen up the batter because it was like cookie dough! They did turn out! Only thing I can think of that may have been the problem was that I did not let the chocolate mixture stand for 5 minutes before mixing it until smooth. It may have seized.
I thought that it was the amount of chocolate that I used because in your intro you mentioned 4ounces.. and the actual recipe state 5 ounces. Regardless.. they were fine! I will attempt again ! Thankyou!
Gotcha! So sorry about that, I see the error. The recipe is correct at 5 ounces, but I updated the intro text (we must have been daydreaming about the frosting haha!). Thanks for your feedback!
Hi! Just confirming if you can use unsweetened baking chocolate instead of bittersweet (as written above) 🙂 Would like to try these and i have some unsweetened baking chocolate in my pantry.
Hi Jessica! I’m sorry, that was an error written on my part in response to the reader’s comment about the measurement of the chopped chocolate used. We’ve only used bittersweet chocolate with these cupcakes; however you’re welcome to try unsweetened! Just know that your cupcakes will be less sweet. Let us know how it goes if you give it a try 🙂
