Ingredients You’ll Need

The magic of this Brownie Cupcakes with Chocolate Buttercream Frosting Recipe lies in its simple, classic ingredients. Each one plays a vital role in crafting a texture that’s tender yet rich, and a flavor that balances sweetness with deep cocoa notes.

• Brownie Mix: The foundation, providing the perfect chocolate base with convenience and consistent results.
• All Purpose Flour (½ cup): Helps give the cupcakes just the right structure without weighing them down.
• Granulated Sugar (½ cup): Adds sweetness and enhances the brownie’s caramelized edges.
• Baking Powder (1½ teaspoons): Ensures the cupcakes rise with a tender crumb and light texture.
• Unsweetened Cocoa Powder (2½ tablespoons): Boosts the chocolate flavor and deepens the overall richness.
• Unsalted Butter, melted (1 stick): Adds moisture and a luscious mouthfeel to the batter.
• Sour Cream (1 cup): Keeps the cupcakes moist and brings a subtle tang that cuts through the sweetness.
• Hot Coffee or Hot Water (½ cup): Intensifies the chocolate’s depth without overpowering.
• Large Eggs (3): Bind ingredients while lending structure and tenderness.
• Fudge Packet (if included): Optional, but a delicious bonus for an even fudgier bite.
• Unsalted Butter, softened (1½ sticks): For the buttercream—gives it that creamy, dreamy consistency.
• Powdered Sugar (2½ cups): Sweetens and thickens the frosting to perfection.
• Unsweetened Cocoa Powder, sifted (½ cup): Creates an indulgent chocolate buttercream with depth.
• Milk (1-2 tablespoons): Adjusts the frosting’s texture to be silky smooth.
• Vanilla Extract (1 teaspoon): Adds warmth and layers of flavor to the frosting.
• Salt (1 teaspoon): Enhances all the chocolatey goodness by balancing sweetness.

How to Make Brownie Cupcakes with Chocolate Buttercream Frosting Recipe

Step 1: Preheat and Prepare

Start by preheating your oven to 350°F (175°C). Line a cupcake pan with paper liners—this will keep your brownies from sticking and make clean-up a breeze. Ready the stage for your delicious masterpiece.

Step 2: Mix Dry Ingredients

In a large bowl, whisk together the brownie mix, all-purpose flour, granulated sugar, cocoa powder, and baking powder until everything is blended evenly. This step ensures that the leavening agents and chocolate are distributed perfectly for that signature texture.

Step 3: Combine Wet Ingredients

Next, add the eggs, sour cream, melted butter, fudge packet (if you have it), and hot coffee or water to the dry mix. Stir gently with a rubber spatula until your batter is smooth and glossy—this is where those fudgy dreams start coming true.

Step 4: Fill Cupcake Liners

Using about ¼ cup of batter per cupcake, fill each liner evenly. Don’t overfill or your cupcakes may spill over, but you do want enough batter for a nice domed top that’s perfect for frosting.

Step 5: Bake to Perfection

Bake at 350°F (175°C) for 18-20 minutes. You’ll know they’re ready when a toothpick inserted into the center comes out clean or with just a few moist crumbs clinging to it. This means the cupcakes are perfectly baked—moist inside with just the right amount of tenderness.

Step 6: Cool Completely

Transfer your cupcakes to a wire rack to cool. This step is crucial because frosting warm cupcakes can cause the buttercream to melt and slide right off, and we want those swirls to hold beautifully.

Step 7: Prepare the Chocolate Buttercream

In a clean bowl, beat the softened butter on low to medium speed until creamy and smooth. Add vanilla extract and blend it in completely to infuse the frosting with warmth and depth.

Step 8: Add Dry Ingredients to Frosting

Gradually mix in powdered sugar, sifted cocoa powder, and salt. Pour most of the milk in at this point and continue beating at low speed. Increase to medium speed as the mixture thickens, creating a rich, fluffy chocolate buttercream that’s just begging to be spread.

Step 9: Adjust Frosting Consistency

If the frosting seems too thick, add a touch more milk, a teaspoon at a time, until it’s smooth and spreadable. If it’s too thin, sprinkle in additional powdered sugar until it reaches the perfect texture for piping or spreading.

Step 10: Frost Your Cupcakes

Once cooled, generously frost each brownie cupcake using a piping bag fitted with your favorite tip or simply a knife for a rustic look. For an extra touch, top with mini chocolate chips, sprinkles, or edible glitter for visual charm and added texture.

Step 11: Store and Enjoy

Store your cupcakes in an airtight container at room temperature for 1-2 days. If you want to keep them longer, refrigeration is best—just let them come back to room temperature before serving for the best flavor and texture.

How to Serve Brownie Cupcakes with Chocolate Buttercream Frosting Recipe

Garnishes

Adding garnishes to your brownie cupcakes takes them from delightful to show-stopping. Think mini chocolate chips, chopped nuts, or even a sprinkle of sea salt to bring out the complex chocolate flavor. A dusting of powdered sugar or a few fresh raspberries can also brighten the presentation and balance the richness.

Side Dishes

Pair these brownies with a scoop of vanilla ice cream or a dollop of freshly whipped cream for a classic combo. For something fruitier, sliced strawberries or a berry compote bring a refreshing contrast. A cup of rich espresso or creamy hot chocolate also complements the deep chocolate layers perfectly.

Creative Ways to Present

Try arranging your brownie cupcakes on a tiered stand for a gorgeous dessert table centerpiece. You can also use decorative cupcake wrappers or tie a cute ribbon around each liner if gifting. Serving them alongside a drizzle of caramel or raspberry sauce adds a gourmet touch that will impress any crowd.

Make Ahead and Storage

Storing Leftovers

If you have any leftover brownie cupcakes (and we promise, you might!), keep them fresh by storing in an airtight container at room temperature for up to two days. This keeps the frosting creamy and the texture tender without drying out.

Freezing

To freeze, place unfrosted cupcakes on a baking sheet until hard, then transfer to a freezer-safe bag or container. Frosted cupcakes can also be frozen but should be wrapped tightly in plastic wrap and placed in an airtight container to protect the frosting. Thaw them overnight in the fridge to preserve their lovely texture and flavor.

Reheating

If you prefer your brownie cupcakes slightly warm, gently heat them in a microwave for 10-15 seconds. Avoid reheating more than once to keep that perfect fudgy texture intact. Keep the frosting cool or add a fresh swirl after warming for the best experience.

FAQs

Can I use homemade brownie batter instead of a boxed mix?

Absolutely! Using a homemade brownie batter will give you full control over flavors and ingredients, but the boxed mix makes this recipe quick and foolproof. Just make sure your batter isn’t too dense to achieve the cupcake-like texture.

Is it necessary to use coffee or can I substitute it?

The hot coffee enhances the chocolate flavor without adding a noticeable coffee taste. You can substitute with hot water if you prefer, but coffee helps bring a richer depth that’s hard to beat.

Can I make the cupcakes gluten-free?

Yes! Substitute the all-purpose flour with a gluten-free blend that includes xanthan gum for best results. Just check the brownie mix you use is gluten-free as well.

How long does the chocolate buttercream frosting last?

The frosting stays fresh in the refrigerator for up to a week when stored in an airtight container. Make sure to bring it back to room temperature and give it a quick whip before piping for the best texture.

Can I color the frosting?

Definitely! Use a little bit of gel food coloring to tint your buttercream without altering its consistency. This is perfect for themed parties or adding some festive fun.
