    Why You’ll Love These Cupcakes

    • Bite-sized and great for sharing (or not)
    • Soft, fluffy, and full of chocolate flavor
    • Quick and easy to make (even for rookies)
    • Easy to customize with different frosting, fillings, and toppings

    Recipe Ingredients

    Labeled ingredients for mini chocolate cupcakes on a white backdrop.

    Oil: Keeps the cupcakes soft and moist. Canola or vegetable oil works best, but melted butter is an option if you want a richer flavor (just know the texture may be a little different).

    All-purpose flour: The key ingredient that gives cupcakes structure. Some recipes use cake flour, but all-purpose is the best choice here. If you’re curious about the difference, check out our post, What is all-purpose flour?

    Cocoa powder: Use natural unsweetened cocoa powder for this recipe. You can try dark cocoa powder for a more intense chocolate flavor.

    Sour cream: Adding sour cream makes these cupcakes extra moist and rich.

    Butter: We like to use salted butter for the frosting but you can swap it out for unsalted, just be sure to add ¼ teaspoon of salt for the best flavor.

    Heavy cream: A little bit of heavy cream makes the frosting smooth and creamy. Milk or half-and-half can be used as a substitute.

    A full ingredient list with exact amounts can be found in the recipe card below.

    Recipe Variations

    Switch up the frosting. We top our mini chocolate cupcakes with chocolate buttercream, but you can use any flavor you like. Some of our favorites are whipped milk chocolate ganache and vanilla American buttercream frosting.

    Try a flavor twist. Change up the cupcake batter by adding espresso powder, peppermint extract, white chocolate chips, or even a pinch of cinnamon and cayenne for a little spice.

    Add extra toppings. Make your cupcakes even more fun with sprinkles, chocolate shavings, caramel drizzle, shredded coconut, chopped nuts, or fresh berries.

    Add a filling. Fill the center of your mini chocolate cupcakes before frosting for a little surprise in every bite. Check out this video tutorial on how to fill cupcakes from Sally's Baking Addiction.

    How To Make Mini Chocolate Cupcakes

    ✏️ Prep Tip: Use Room Temperature Ingredients
    Let your eggs, sour cream, and butter sit out for about 15–20 minutes before you start baking. It helps everything mix smoothly and makes the cupcakes soft and fluffy. In a hurry? Here are some quick ways to soften butter!

    make the cupcakes

    Whisking dry ingredients for mini chocolate cupcakes in a large gray mixing bowl.

    Step 1: In a medium bowl, combine the flour, baking powder, baking soda, salt, and cocoa powder. Whisk the dry ingredients together until fully combined and set aside.

    Step 2: In a large mixing bowl, combine the granulated sugar and oil until fully incorporated. Add the egg, vanilla extract, and sour cream. Mix until combined.

    Step 3: Using a wooden spoon or spatula, gently stir in half of the flour mixture, followed by the buttermilk. Add in the rest of the flour mixture and mix just until the ingredients are fully combined.

    Step 4: Preheat the oven to 350°F and prepare a 24-cup mini cupcake pan with mini cupcake liners. Use a small cookie scoop to fill the cupcake liners about ⅔ of the way full. Bake them for 10 minutes or until the center tests done with a toothpick. Let the cupcakes cool in the pan for about 10 minutes before transferring them to a wire cooling rack to cool completely.

    ✏️ Baking Tip: If you prefer not to use cupcake liners, just lightly grease the pan with cooking spray before adding the cupcake batter.

    make the frosting

    Creaming butter with hand mixer in a gray mixing bowl on a white background.

    Step 5: In a medium mixing bowl, cream the softened butter with an electric mixer for 1-2 minutes until it’s smooth and creamy.

    Step 6: Mix in the unsweetened cocoa powder and vanilla extract.

    Step 7: Add in the powdered sugar one cup at a time, mixing between additions. This helps keep the frosting smooth. Add 2-3 tablespoons of heavy cream or milk (as needed) until it’s the perfect consistency.

    Step 8: Once they are completely cooled, pipe a dollop of chocolate buttercream on top of each cupcake. (You can also just use a frosting knife to spread it on instead.) Note that frosting the cupcakes when they are too warm will make the frosting to melt off. Finally, add any toppings or decorations and enjoy!

    Expert Tips

    Measure the flour correctly. The easiest way to measure flour is the spoon and level method. Spoon the flour into the measuring cup, then level it off with the back of a knife (or other straight edge).

    Make your own buttermilk. If you don’t have buttermilk, mix 1 cup of milk (minus 1 tablespoon) with 1 tablespoon of white vinegar or lemon juice. Stir it and let it sit for 5 minutes before using.

    Stick with natural unsweetened cocoa powder. Use natural unsweetened cocoa powder for this recipe, not dutch-processed. If you want more info, check out this guide on dutch-process vs. natural cocoa powder from Sally’s Baking Addiction.

    Don’t overfill the cupcake liners. Fill the liners about ⅔ full (a small cookie scoop works great). Too much batter can make the mini chocolate cupcakes overflow and bake unevenly.

    Swap out the heavy cream for evaporated milk. For a smoother buttercream, try using evaporated milk instead of heavy cream.

    Decorate like a pro. Use a star tip to pipe on the frosting for a bakery-style finish. Sprinkles, chocolate curls, or fresh fruit are a great finishing touch!

    How To Store Mini Cupcakes

    These mini chocolate cupcakes freeze well and stay fresh for months, making them great for prepping ahead or keeping a stash on hand.

    • Unfrosted cupcakes: 2 days at room temperature, 1 week in the fridge, or 2 months in the freezer (thaw before frosting).
    • Frosted cupcakes: Best fresh, but store in the fridge after a day.
    • Chocolate buttercream: Stays good for a month in the fridge—just soften and rewhip before using.

    Mini Chocolate Cupcake FAQ’s

    Can I make regular-sized cupcakes with this mini chocolate cupcake recipe?

    Yes! This recipe makes 12 standard-sized chocolate cupcakes. Just bake them at 350°F for 18-22 minutes.

    Can I use dutch-processed cocoa powder instead of natural unsweetened cocoa powder for these chocolate cupcakes?

    Nope! Natural unsweetened cocoa powder reacts with the baking soda to make the cupcakes rise. Dutch-process won’t react the same way, affecting the flavor and texture of your cupcakes.

    How can I tell when these mini cupcakes are done baking?

    To check if they're done, insert a toothpick into the center of one of the cupcakes. If it comes out clean or with a few crumbs, they’re done! If you see batter, give them another minute or two in the oven and check again.

    How do I fix buttercream that’s too thick or too thin?

    If the frosting is too thick, add milk or cream, one tablespoon at a time, until it’s the right consistency. For frosting that is too thin, add powdered sugar a little at a time until it’s as thick as you like.
