How to Make the BEST Chocolate Cupcakes

This recipe underwent extensive testing to perfect. Below is a complete explanation of every major element in case you wanted to learn more about the science and process behind all of it.

I’ve tried to answer any questions you might have below, but feel free to leave a comment with any other questions.

How to Make my Easy Chocolate Cupcake Recipe:

1. Mix the chocolate, cocoa powder and espresso powder. In a medium heatproof bowl add 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.
2. Preheat oven and prepare the muffin tin. Meanwhile, preheat oven to 350°F. Line a standard 12-cup muffin tin with paper liners.
3. Whisk together the dry ingredients. In a small bowl, whisk together the flour, sugars, salt, and baking soda. Set aside.
4. Mix together the wet ingredients. Whisk sour cream, oil, eggs, egg yolk, vinegar, and vanilla into the cooled chocolate mixture until smooth. Scrape down the sides and bottom of the bowl.
5. Carefully stir in the flour mixture. Stir in the flour mixture until smooth, being careful not to overmix.
6. Portion out your cupcakes. Using a spring-loaded scoop, divide the batter evenly among prepared muffin cups until 3/4 full.
7. Bake. Bake in the preheated oven until cupcakes are set and firm to the touch, or a toothpick or cake tester inserted just has a few moist crumbs attached – about 17 to 20 minutes. Let cupcakes cool in pan on a wire rack for 10 minutes before removing from pan to cool completely on a cooling rack.

Chocolate Cupcake Ingredients

The Best Chocolate to Use for Chocolate Cupcakes:

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.

Do I Have to Use Dutch Process Cocoa Powder?

I do recommend you stick with the Dutch-process cocoa as it actually works differently on a chemical level compared to regular natural cocoa. You can learn more about the differences between cocoa powders here.

You can find it at many gourmet food stores, like Whole Foods, Sur la Table, and Williams-Sonoma. One of the best surprising parts about Dutch Process Cocoa is that it almost always contains more cocoa butter (fat!) than your typical grocery store cocoa powder. This means more moisture, richness, and chocolate flavor! Learn more about cocoa powder + fat here.

If you must use regular unsweetened cocoa powder in this recipe, then omit the vinegar. Your cupcakes may be a little more dry if using something like Hershey’s or Nestle.

The frosting uses melted chocolate for the most intense and pure chocolate flavor possible. I like to use semisweet, but feel free to use milk or bittersweet chocolate instead. It’s totally up to you!

What is the Secret to Super MOIST Cupcakes?

1. This recipe calls for vegetable oil instead of melted butter. I went back and forth on this for a bit and wound up choosing the oil because it creates an ultra moist texture and open, slightly spongy crumb which is perfect for chocolate cupcakes. For more details on how these two fats affect tenderness, flavor, and texture, check out my Butter vs. Oil in Baking article.
2. Since oil is liquid at room temperature, it gives a better sensation of moistness than butter does.
3. Be sure to also use full fat ingredients and don’t reduce the sugar in this recipe. Sugar actually helps contribute to moistness if you can believe it!
4. Lastly, be sure not to accidentally over measure your flour and cocoa powder. Spoon both ingredients into their measuring cups then level off the excess with a knife. Or better yet, use a digital kitchen scale. Check out my How to Measure Flour article for a step-by-step on how to accurately measure your dry ingredients.

Hot Water and Espresso Powder in Chocolate Cupcakes

If you bake chocolate cake or cupcakes a lot, you’ve probably seen quite a few recipes that utilize hot water or even hot coffee. It helps to dissolve and ‘bloom’ the cocoa powder to bring out as much flavor with as few cocoa lumps as possible. In my Best Chocolate Cupcake recipe, I use a combination of hot water and instant espresso powder. The espresso simply enhances the chocolate flavor without actually being perceptible.

Do I Have to Use Espresso Powder?

Alternatively, you could use hot coffee for the same effect. Instant coffee and water will also work. Or you can omit it altogether if you’d prefer.

Sugar(s)

Most of my initial recipe tests used only granulated sugar for the cupcakes. Then, I thought I’d try to add in a bit of brown sugar. The resulting chocolate cupcakes were flavorful, moist, and slightly chewy. Perfect!

Eggs

The more whole eggs a cake recipe has, the richer it’ll be. I repeated one of my favorite baking tricks and added in an egg yolk. It 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.

Is There an Egg Substitute For Chocolate Cupcakes?

I have yet to find an amazing egg substitute for this recipe. My friend Gemma from Bigger Bolder Baking has an excellent resource on egg substitutes.

Leavener

Oh man, this is where I encountered the most frustration. I went back and forth on this. When I used both baking soda and baking powder, the cupcakes rose to a beautiful height while baking but then fell and collapsed slightly as they cooled. Bummer. That was too much leavener.

I went back to only baking soda, which is more effective per teaspoon than baking powder, but had to add vinegar to the recipe. Why? Well because there wasn’t much acid for the baking soda to react with originally. Dutch-process cocoa powder has been neutralized of its acid, so it was only the sour cream and small amount of brown sugar. For tall and light cupcakes, we need enough leavening so baking soda + vinegar did the trick. This is why you omit the vinegar if you’re using natural cocoa powder.

Flour

I tried testing with bread flour after seeing a few ‘ultimate’ recipes elsewhere that used it, but found that all-purpose worked just as well. Since all-purpose flour is more readily available, I stuck with that to make things easiest for you.

Sour Cream

I find that sour cream adds such a lovely richness and balance of flavor to cupcakes, so I just had to include it here. I think it definitely works best, but full fat plain yogurt also makes a fine alternative in chocolate cupcakes.

The Chocolate Buttercream Frosting

When I originally published this recipe, it used the more difficult 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 easier but equally as delicious, I swapped in an American-style chocolate buttercream that’s made extra special with two additions. The frosting contains cooled chocolate ganache for extra chocolate flavor and fudgy richness.

For an extra smooth and rich frosting, opt for organic powdered sugar and high fat cocoa powder. The full explanation for both is found here.

My Favorite Cupcake Tools:

• Cupcake liners: these ones are my favorite for cupcakes that don’t stick to the liner.
• Piping tip: I used the Ateco #828 piping tip for swirling on the chocolate frosting on these cupcakes. Any large open star tip will work!
• Piping bags: I love these ones.

How to Store Chocolate Cupcakes:

Cupcakes can be stored in an airtight container at room temperature for up to 1 day.

Can You Freeze Cupcakes?

If storing for longer than a week, wrap unfrosted cupcakes individually in plastic wrap (this prevents 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 to defrost at room temperature for about 1 to 2 hours. More details on how to freeze and make desserts ahead of time in my *free* Make Ahead Baking Guide.
