Chocolate Cupcakes

Sweet enough for kids but intensely chocolate enough for grown-ups, these are my go-to chocolate cupcakes.
Starting a baking business specializing in cakes and cupcakes sparked my passion for creating recipes, which was the impetus for creating Once Upon a Chef many years ago. These chocolate cupcakes, a delicious discovery from that time (and the mini version of my favorite chocolate cake), have been my go-to ever since. The cake recipe is wonderfully simple—a one-bowl recipe that and yields an ultra moist, deeply chocolate, and tender crumb. And the chocolate buttercream, modestly adapted from Cook’s Illustrated, is fast and foolproof—a welcome change from most homemade chocolate frostings, which can be temperamental and take hours to set.

What You’ll Need To Make Chocolate Cupcakes
For the Cupcakes
- All-Purpose Flour: The foundation of the cupcakes. For accurate measuring, use the spoon and level method: spoon the flour into your measuring cup and level it off with the back of a knife.
- Granulated Sugar: Adds sweetness and helps create a moist and tender crumb.
- Unsweetened Natural Cocoa Powder: Key for that rich chocolate flavor. It’s important to note that natural cocoa powder isn’t interchangeable with Dutch-process cocoa powder due to differences in acidity.
- Baking Powder and Baking Soda: These leavening agents help your cupcakes rise and become light and fluffy. (Understand the difference between baking soda vs baking powder.)
- Eggs: Add structure, richness, and stability to the batter.
- Vegetable Oil: Adds moisture to the cupcakes, ensuring they’re soft and not dry. Oil-based cakes tend to stay moist longer than those made with butter.
- Sour Cream: A secret weapon for moistness! Sour cream not only adds richness and a subtle tang but also reacts with baking soda for a tender texture.
- Vanilla Extract: Rounds out the sweetness and brings complexity to the overall taste.
- Boiling Water: Adds moisture and intensifies the cocoa’s flavor, resulting in a more robust chocolate taste.

For the Frosting
- Milk or Semi-Sweet Chocolate: Choose based on your preference for sweetness. Milk chocolate offers a milder, sweeter taste, while semi-sweet chocolate adds a deeper chocolate flavor. The quality of the chocolate can significantly affect the frosting’s flavor, so opt for a good brand.
- Unsalted Butter: Make sure it’s softened but still cool, which ensures that it blends well without becoming too runny. Unsalted butter allows you to control the frosting’s saltiness more precisely.
- Confectioners’ Sugar: This finely ground sugar, also known powdered sugar, dissolves easily, preventing any grittiness in the frosting.
- Natural Unsweetened Cocoa Powder: Adds a rich and deep chocolate flavor.
- Light Corn Syrup: Adds gloss and sheen to the frosting, making it smooth and spreadable. It also helps in stabilizing the texture.
- Vanilla Extract: Rounds out the flavors and adds depth.

Step-by-Step Instructions
Step 1: Make the Cupcakes
In the bowl of a stand mixer fitted with the paddle attachment, combine the flour, sugar, cocoa powder, salt, baking powder, and baking soda. Mix on low speed for 30 seconds to combine.
Add the eggs, oil, and sour cream.
Mix on low speed until combined.
Increase the speed to medium and beat for 2 minutes. Then, reduce the speed to low and gradually pour in the hot water (be careful to pour very slowly so it doesn’t splash). The batter will be soupy. Stop the mixer and scrape down the sides and bottom of the bowl; mix again until evenly combined.
Divide the batter evenly into the cupcake liners.
Bake for 18 to 20 minutes, or until the cupcakes are set and a toothpick inserted into the center of a cupcake comes out clean.
Cool the cupcakes in the pan for about 10 minutes, then transfer them to a rack to cool completely.
Step 2. Make the Frosting
Place the chocolate in a microwave-safe bowl.
Cook in the microwave in 20-second intervals, stirring in between, until it’s about three-quarters of the way melted. Stir, allowing the residual heat in the bowl to melt the remaining chocolate completely. (If necessary, place the chocolate back in microwave for a few seconds.) Set aside to cool.
In a food processor, combine the butter, confectioners’ sugar, cocoa powder and salt.
Process until smooth, about 30 seconds, scraping down the sides of the bowl as needed. Then add the corn syrup and vanilla.
Process until just combined, 5 to 10 seconds. Scrape down the sides of the bowl, then add the lukewarm melted chocolate. Pulse until smooth and creamy, 10 to 15 seconds. Do not overmix.
When the cupcakes have cooled, use a small offset spatula or butter knife to swirl the frosting on top.
Frequently Asked Questions
Yes, you can make these cupcakes a day in advance. Once they have completely cooled, store them in an airtight container at room temperature.
Yes, the cupcakes can be frozen without the frosting for up to 3 months. Let them cool completely, wrap them individually in plastic wrap, and then in foil. Thaw them overnight on the countertop before serving. (Wait until the cupcakes are completely defrosted to ice them.)

Ingredients
For the Cupcakes
- 1½ cups all-purpose flour, spooned into measuring cup and leveled off with knife
- 1½ cups granulated sugar
- ¾ cup unsweetened natural cocoa powder, such as Hershey’s
- ¾ teaspoon salt
- 1½ teaspoons baking powder
- ¾ teaspoon baking soda
- 2 large eggs, lightly beaten
- ¼ cup vegetable oil
- ¾ cup sour cream
- 1 teaspoon vanilla extract
- ¾ cup boiling water
For the Frosting
- 8 ounces milk or semi-sweet chocolate, broken into small pieces (see note)
- 2½ sticks (20 tablespoons) unsalted butter, softened but still cool
- 1¼ cups Confectioners' sugar
- ¾ cup natural unsweetened cocoa powder, such as Hershey's
- Pinch salt
- ¾ cup light corn syrup
- 1 teaspoon vanilla extract
Instructions
For the Cupcakes
- Preheat the oven to 350°F and set two oven racks in the centermost positions. Line two 12-cup muffin tins with paper liners.
- In the bowl of a stand mixer fitted with the paddle attachment, combine the flour, sugar, cocoa powder, salt, baking powder, and baking soda. Mix on low speed for 30 seconds to combine. Add the eggs, oil, sour cream, and vanilla and mix on low speed until combined.
- Increase the speed to medium and beat for 2 minutes. Then, reduce the speed to low and gradually pour in the hot water (be careful to pour very slowly so it doesn’t splash). The batter will be soupy. Stop the mixer and scrape down the sides and bottom of the bowl; mix again until evenly combined.
- Pour the batter evenly into the prepared muffin tins (they should be about halfway full). Bake for 18 to 20 minutes, or until the cupcakes are set and a toothpick inserted into the center of a cupcake comes out clean.
- Cool the cupcakes in the pans for about 10 minutes, then transfer them to a wire rack to cool completely.
For the Frosting
- Place the chocolate in a microwave-safe bowl and cook in the microwave in 20-second intervals, stirring in between, until about three-quarters of the way melted. Stir, allowing the residual heat in the bowl to melt the remaining chocolate completely. (If necessary, place the chocolate back in microwave for a few seconds.) Set aside to cool.
- In a food processor, process the butter, sugar, cocoa powder and salt until smooth, about 30 seconds, scraping down the sides of the bowl as needed. Add the corn syrup and vanilla and process until just combined, 5 to 10 seconds. Scrape down the sides of the bowl, then add the lukewarm chocolate and pulse until smooth and creamy, 10 to 15 seconds. Do not overmix. The frosting can be used immediately or held at room temperature for up to 3 hours.
- When the cupcakes are completely cool, use a small offset spatula or butter knife to swirl the frosting lavishly over top. The cupcakes are best enjoyed fresh on the day they are made, but they will keep for two days stored in an airtight container at room temperature.
- Note: If making this cake for children, I recommend using milk chocolate for the frosting (Hershey or Lindt milk chocolate bars work well). Semi-sweet chocolate will lend a more intense chocolate flavor (Ghirardelli bars for baking are ideal).
- Make-Ahead/Freezer-Friendly Instructions: The cupcakes can be made up to one day ahead of time and stored in an airtight container at room temperature. They can also be frozen without the frosting for up to 3 months. Let them cool completely, wrap them individually in plastic wrap, and then in foil. Thaw overnight on the countertop before serving. (Wait until the cupcakes are defrosted to ice them.)

Great recipe, so delicious. Big hit with my family, so chocolatey and moist.
I didn’t have enough sour cream so used part sour cream and part greek yogurt worked perfectly.
These are the most moist and delicious little chocolate morsels. A winner again Jennifer!
These are the MOST wonderful cupcakes for chocolate lovers. I made these for dinner last night and got rave reviews for Jenn’s expertise and creativity! My son deemed this icing the best he’s ever tasted. I don’t own a food processor, so I used a mixer for the icing and ALWAYS follow Jenn’s recipes as written. Thanks, Jenn!
Another hit by Jenn that will become a staple in my household!
Wonderful cupcakes! Clear and straightforward recipe, easy to make, and turned out perfectly – moist, flavorful and delicious. The chocolate isn’t overpowerful, but just the right for my family – well described as kid and adult friendly.
I paired with Jenn’s Old-Fashioned Vanilla Buttercream icing and it was a wonderful balance. If you want more chocolate punch, pair with the suggested chocolate.
Thanks Jenn for making me look like a star and making my family happy!
Hi Jenn! I love your recipes, they always turn out amazing. Is there any way to swap out or skip the corn syrup in this recipe? Thanks so much!
So glad you like the recipes! Unfortunately, you really need to corn syrup as it stabilizes the frosting. I would just use a basic chocolate buttercream, like this one. Hope that helps!
Hi, I found your site about a year ago, and have used your recipes and tips ever since! I made these cupcakes and they are cooling right now. Question about the frosting…..Will it work well using a piping bag to decorate? Or, is the reason for spreading it because it won’t hold up to piping to make fancy? It get really warm over here, (mid 80s), It is humid too. Thanks!
Hi Sabrena! So glad you enjoy the recipes! This frosting will not hold up for piping, especially in the heat; it is soft and creamy. Hope you enjoy!
This is our go to birthday cupcake recipe. We usually only use ¼ of the frosting, so we ended up cutting the recipe down in our household.
Hi jenn
I have a doubt with sourcream it has to be a room temperature?
Hi Fanny, No need for it to be room temperature. Hope you enjoy!
Hello, would it come out the same if I used a gluten-free flour like Bob Mills?
Hi Melissa, I’ve never tried it but I think it should work.
Hi Jenn
Can i change unsweetened natural cocoa instead of 3/4 cup Hershey’s Special Dark Cocoa?
I don’t recommend it, Fanny – sorry!
