Ingredients You’ll Need

Every ingredient in this recipe is hand-picked to make sure your Chocolate Cupcakes with Blackberry Buttercream turn out vibrant, flavorful, and wonderfully tender. You probably have most of these at home already, and each brings something essential to the table—chocolatey richness, plush crumb, vibrant berry color, and sweet-tangy notes that make every bite special.

All-purpose flour: Provides structure, ensuring the cupcakes are delightfully soft yet sturdy enough to hold all that luscious frosting.
Unsweetened cocoa powder: The source of deep, true chocolate flavor—choose a high-quality brand for the richest taste!
Baking soda & baking powder: These leaveners help the cupcakes rise light and fluffy every time.
Salt: Balances the sweetness and intensifies the chocolate notes.
Eggs: Bind the ingredients while adding moisture, richness, and that coveted tender crumb.
Granulated sugar: Sweetens and keeps the cupcakes moist.
Vegetable oil: Oil ensures a super-moist, almost melt-in-your-mouth texture—skip the butter here for a plush result.
Buttermilk: Adds a gentle tang and softens the crumb beautifully.
Vanilla extract: Rounds out the chocolate and berry flavors with warmth and depth.
Hot water: Helps the cocoa bloom and gives the batter a wonderfully smooth, pourable consistency.
Unsalted butter (softened): For the blackberry buttercream, butter is essential for a creamy, fluffy texture.
Powdered sugar: Brings sweetness and structure to the silky frosting without any grittiness.
Blackberry puree (strained): Infuses the buttercream with real berry flavor and a stunning purple hue—strain for a smooth finish!
Pinch of salt: Just a bit balances the sweetness and brings the berry flavor to life.

How to Make Chocolate Cupcakes with Blackberry Buttercream

Step 1: Prep Your Oven and Pans

Get started by preheating your oven to 350°F (175°C) and lining a standard muffin tin with paper liners. This simple prep work promises mess-free cupcakes with beautiful, confident shapes—plus, those liners make serving (and clean-up) a breeze!

Step 2: Mix the Dry Ingredients

Whisk together the flour, unsweetened cocoa powder, baking soda, baking powder, and salt in a medium mixing bowl. Taking just a minute to blend these now means your cupcakes bake up evenly and prevent dreaded dry pockets of cocoa later on.

Step 3: Beat Eggs and Sugar

In your largest bowl, beat the eggs and granulated sugar until the mix looks light, smooth, and fluffy. This step is your ticket to melt-in-your-mouth crumb! Don’t rush—give it a couple of minutes for that pale, creamy texture.

Step 4: Add Wet Ingredients

Mix in the vegetable oil, buttermilk, and vanilla extract to the egg mixture, stirring until everything is silky and combined. Each of these brings its own magic: moisture, subtle tang, and fragrant vanilla to support that intense chocolate flavor.

Step 5: Combine Wet and Dry

Add the dry ingredients to the egg mixture, folding gently until you have a thick, rich batter. Then, slowly pour in the hot water and stir just until the mixture is smooth and thin—don’t overmix, or you’ll lose all that luscious airiness!

Step 6: Pour and Bake

Divide the batter evenly between your cupcake liners (about two-thirds full is just right). Pop your tray in the preheated oven and bake for about 18–20 minutes. You’ll know they’re done when a toothpick or cake tester comes out mostly clean with a few moist crumbs. Set aside to cool completely before frosting.

Step 7: Make the Blackberry Buttercream

Beat the softened unsalted butter until it’s fluffy and creamy, then gradually add the powdered sugar. Stream in the strained blackberry puree, vanilla extract, and a pinch of salt, whipping until everything is silky, smooth, and a gorgeous shade of purple. If you want an even deeper berry flavor, try reducing the puree in a saucepan before cooling and adding.

Step 8: Frost and Finish!

Once the cupcakes are completely cool, pipe or swoop the blackberry buttercream generously on top. For the full Chocolate Cupcakes with Blackberry Buttercream effect, consider an extra flourish—like a fresh blackberry or sprig of mint!

How to Serve Chocolate Cupcakes with Blackberry Buttercream

Garnishes

The moment to let your creativity shine! A single fresh blackberry perched atop each cupcake makes a stunning (and delicious) statement, but you can also sprinkle with dark chocolate curls or add a bright mint leaf for a touch of green. The contrast of deep chocolate, radiant purple frosting, and jewel-like berries is simply irresistible.

Side Dishes

Though Chocolate Cupcakes with Blackberry Buttercream are stars all on their own, they pair beautifully with some simple sides. Try serving with sparkling berry lemonade, a scoop of vanilla ice cream, or a plate of juicy fresh raspberries to complement the berry-rich frosting. For grown-up parties, these go spectacularly with a glass of cold milk or even a little dessert wine.

Creative Ways to Present

If you’re hosting, set up a cupcake bar with extra fruit and toppings so guests can decorate their own treats. Elegant cake stands or rustic wooden boards make these Chocolate Cupcakes with Blackberry Buttercream even more eye-catching. Mini cupcakes are perfect for parties, while full-sized versions steal the show at birthdays or showers.

Make Ahead and Storage

Storing Leftovers

Keep any leftover Chocolate Cupcakes with Blackberry Buttercream in an airtight container at room temperature for up to two days. If your kitchen is particularly warm or humid, it’s best to refrigerate to preserve the luscious buttercream, but bring cupcakes to room temperature before serving for the best texture and flavor.

Freezing

You can freeze the cupcakes unfrosted and unfilled. Simply wrap each cooled cupcake tightly in plastic wrap and store in a freezer-safe bag or box for up to two months. To freeze fully frosted cupcakes, arrange them on a tray to freeze solid, then gently wrap and store. Thaw overnight in the fridge and let them return to room temperature before eating.

Reheating

There’s no need to reheat these cupcakes unless you’re thawing from frozen. If so, unwrapped cupcakes come back to life at room temperature or with a very brief 10-second zap in the microwave (without the frosting). Frosted cupcakes are best enjoyed at room temp for soft, creamy buttercream.

FAQs

Can I use frozen blackberries for the buttercream?

Absolutely! Just thaw them thoroughly and strain to remove seeds. Simmer if needed to intensify the flavor and cool before adding to your buttercream.

How do I make the cupcakes extra chocolatey?

Boost the chocolate flavor by adding a handful of mini chocolate chips to the batter before baking, or use Dutch-process cocoa for a more intense, decadent result.

Can I make the Chocolate Cupcakes with Blackberry Buttercream ahead of time?

Yes, both the cupcakes and buttercream can be made 1–2 days ahead. Store cupcakes covered at room temperature and buttercream in the fridge. Assemble just before serving for the freshest experience.

What’s the best way to pipe the buttercream?

Use a large open star or round piping tip for rosettes or swirls that show off the berry color. If you’re feeling playful, try making a two-tone effect by streaking a bit of extra berry puree along one side of the piping bag.

Do I have to strain the blackberry puree?

For the smoothest, silkiest buttercream, straining the seeds out of the blackberry puree is highly recommended. If you don’t mind a bit of texture (and love that “homemade” look), you can skip it, but your frosting might have a bit of crunch.

Final Thoughts

I hope these Chocolate Cupcakes with Blackberry Buttercream light up your kitchen and sweeten any special moment. There’s just something magical about the combination of bold chocolate and tart blackberry in every bite. Give this recipe a try—you’ll instantly see why I keep it on repeat for birthdays, brunches, or when only the most stunning cupcakes will do!
