Ingredients You’ll Need
These ingredients are simple staples but each plays a crucial role in bringing the Chocolate Cupcakes with Blackberry Buttercream Recipe to life. From the rich cocoa powder that delivers chocolate depth to the fresh blackberries that add a burst of natural sweetness, every component is essential.
- 1/2 cup all-purpose flour: Provides the structure and tender crumb to the cupcakes.
- 1/4 cup unsweetened cocoa powder: Adds that unmistakable, deep chocolate flavor and dark color.
- 1/2 teaspoon baking powder: Helps the batter rise for light, fluffy cupcakes.
- 1/4 teaspoon baking soda: Works alongside the baking powder to give just the right lift.
- 1/4 teaspoon salt: Enhances all the flavors, balancing the sweetness.
- 1/2 cup granulated sugar: Sweetens the cupcakes perfectly without overpowering the chocolate.
- 1/4 cup vegetable oil: Keeps the cupcakes moist and soft with a tender crumb.
- 1 large egg: Binds ingredients together, ensuring a smooth texture.
- 1/2 teaspoon vanilla extract: Adds warmth and depth to the flavor profile.
- 1/4 cup buttermilk: Provides acidity to tenderize the cupcake crumb and adds a slight tanginess.
- 1/2 cup unsalted butter, softened: The base for the buttercream frosting, giving it rich creaminess.
- 2 cups powdered sugar: Sweetens and thickens the buttercream for that perfect frosting consistency.
- 1/2 teaspoon vanilla extract: Lifts the flavor of the buttercream, balancing the blackberry sweetness.
- 2 tablespoons blackberry jam: The star ingredient in the buttercream, infusing it with natural fruit flavor and a beautiful hint of purple.
- Fresh blackberries (for garnish, optional): Adds an elegant, fresh touch when topping off each cupcake.
How to Make Chocolate Cupcakes with Blackberry Buttercream Recipe
Step 1: Prepare Your Oven and Muffin Tin
Start by preheating your oven to 350°F (175°C). Then, line a standard muffin tin with 6 cupcake liners to ensure easy removal later and to give your cupcakes their classic shape.
Step 2: Combine the Dry Ingredients
In a medium bowl, whisk together the all-purpose flour, unsweetened cocoa powder, baking powder, baking soda, and salt. This careful mixing helps distribute the leavening evenly and makes sure the cocoa powder doesn’t clump up, setting a great foundation for your cupcakes.
Step 3: Mix the Wet Ingredients
In a separate bowl, whisk together the granulated sugar, vegetable oil, the large egg, and vanilla extract until you get a smooth, homogenous mix. This step is essential for incorporating some air, which keeps your cupcakes tender and light.
Step 4: Combine Wet and Dry Mixtures
Now slowly add the dry ingredients to the wet mixture, alternating with the buttermilk. Stir gently until just combined—overmixing here can make the cupcakes dense, and we want them airy and moist.
Step 5: Fill the Cupcake Liners
Divide the batter evenly among the cupcake liners, filling each about two-thirds full so they have room to rise without spilling over the sides during baking.
Step 6: Bake Until Perfect
Bake the cupcakes for 18 to 20 minutes. The indicator that they’re done? Insert a toothpick into a cupcake’s center and pull it out clean. This ensures the cupcakes are cooked through but still wonderfully moist inside.
Step 7: Cool Completely Before Frosting
Once baked, allow the cupcakes to cool fully in the tin before moving them to a wire rack. Patience is key here because frosting warm cupcakes will cause the buttercream to melt and slide off.
Step 8: Make the Blackberry Buttercream
Beat the softened butter on medium-high speed until creamy. Gradually add the powdered sugar, continuing to beat until the mixture is fluffy and light. Stir in the vanilla extract and the blackberry jam. If the buttercream feels too thick, add a tiny splash of milk to loosen it up, creating that perfectly spreadable texture.
Step 9: Frost and Garnish
Generously frost each cooled cupcake with the blackberry buttercream. For an extra-special touch, top each cupcake with a fresh blackberry—this not only looks stunning but adds a burst of fresh fruit flavor.
How to Serve Chocolate Cupcakes with Blackberry Buttercream Recipe

Garnishes
Beyond the fresh blackberry on top, you might consider a few additional garnishes to elevate these cupcakes. A light dusting of cocoa powder or a small drizzle of melted dark chocolate pairs beautifully. Toasted almond flakes can add a delightful crunch that contrasts the creamy buttercream.
Side Dishes
Pairing these cupcakes with fresh fruit, such as raspberries or sliced strawberries, keeps the dessert plate vibrant and refreshing. A scoop of vanilla bean ice cream or a dollop of whipped cream can turn this treat into an even more decadent indulgence without overwhelming the delicate blackberry flavor in the frosting.
Creative Ways to Present
Consider serving these cupcakes on a rustic wooden board or a vintage cake stand for a charming look. For special occasions, pipe the buttercream using a star tip for beautiful swirls and add edible flower petals or glitter for a whimsical touch. Presentation is half the fun, and with this Chocolate Cupcakes with Blackberry Buttercream Recipe, your creativity will shine.
Make Ahead and Storage
Storing Leftovers
You can store leftover cupcakes in an airtight container at room temperature for up to two days to keep them moist. For longer freshness, refrigeration is best, but bring them back to room temperature before serving for the ideal texture and flavor balance.
Freezing
Both the unfrosted cupcakes and the buttercream-frosted ones freeze well. Wrap each cupcake in plastic wrap and place them in a freezer-safe container or bag. They keep for about 2-3 months. Thaw overnight in the refrigerator before enjoying.
Reheating
If you want to warm up your cupcakes, a quick zap in the microwave for 10-15 seconds does the trick. Avoid heating too long to prevent drying out the cake or melting the frosting.
FAQs
Can I use frozen blackberries for the buttercream?
Absolutely! Just make sure to thaw and strain them well to remove excess liquid before mixing into the buttercream. This helps maintain the perfect frosting consistency.
Is there a substitute for buttermilk in the cupcakes?
You can easily replace buttermilk with regular milk mixed with a teaspoon of lemon juice or vinegar. Let it sit for 5 minutes before using—this will mimic the acidity of buttermilk.
How do I make sure my cupcakes stay moist?
Use oil instead of butter in the batter, don’t overmix, and avoid overbaking. Also, allowing cupcakes to cool properly before frosting them helps trap in moisture.
Can I make this recipe vegan or dairy-free?
Yes, with some swaps: use a plant-based milk like almond or oat milk with a splash of vinegar instead of buttermilk, substitute the egg with a flax or chia egg, and replace butter with a dairy-free margarine for the frosting.
Why is my buttercream grainy?
This usually happens if the butter isn’t softened enough or the powdered sugar wasn’t sifted. Always use room temperature butter and sift your powdered sugar for the smoothest, fluffiest buttercream.
