Introduction

These cream-filled chocolate cupcakes combine rich cocoa flavor with a fluffy vanilla buttercream center and a smooth chocolate ganache topping. Perfect for celebrations or a special treat, they offer a delightful balance of textures and flavors that home bakers will love.

Six chocolate cupcakes are displayed on a white plate with a blue speckled texture, placed on a white marbled surface. Each cupcake has a smooth, glossy dark brown chocolate frosting topped with a white cream zigzag line across the top center. One cupcake is cut in half showing three layers: a rich, dark brown moist cake exterior, a thick creamy white filling at the center, and a thin layer of chocolate frosting covering the cake top just above the filling. The cupcake liners are plain white with some chocolate crumbs on them. photo taken with an iphone --ar 4:5 --v 7

Ingredients

1 cup (125g) all-purpose flour (spooned & leveled)
1/2 cup (42g) unsweetened natural cocoa powder
1 teaspoon baking soda
1/2 teaspoon baking powder
1/2 teaspoon salt
1/3 cup (80ml) vegetable oil (or avocado oil or melted coconut oil)
1 cup (200g) granulated sugar
1 large egg, at room temperature
1 teaspoon pure vanilla extract
1/2 cup (120ml) buttermilk*, at room temperature
1/2 cup (120ml) hot coffee or hot water
6 ounces (170g) semi-sweet chocolate, finely chopped
2/3 cup (160ml or 5.3 ounces) heavy cream
1/2 cup (8 Tbsp; 113g) unsalted butter, softened to room temperature
2 cups (240g) confectioners’ sugar
3 Tablespoons (45ml) heavy cream
2 teaspoons pure vanilla extract
Salt, to taste

Instructions

Step 1: Preheat your oven to 350°F (177°C) and line a 12-count muffin pan with cupcake liners. Since this recipe makes about 15 cupcakes, line a second pan with 3 liners or plan to bake in batches.
Step 2: In a large bowl, whisk together the flour, cocoa powder, baking soda, baking powder, and salt. Set aside.
Step 3: In another bowl, whisk the oil, sugar, egg, vanilla extract, and buttermilk until combined. Pour the wet ingredients into the dry ingredients, add the hot coffee or water, and whisk until the batter is smooth and fully combined. The batter will be thin.
Step 4: Spoon the batter into the cupcake liners, filling each about two-thirds full to avoid spilling. You should have enough batter for 15 cupcakes.
Step 5: Bake for 20 to 22 minutes or until a toothpick inserted in the center comes out clean.
Step 6: Let the cupcakes cool in the pan for 10 minutes, then transfer them to a wire rack to cool completely. If the tops are sticky, chill them in the refrigerator for 20–30 minutes before filling.
Step 7: To make the ganache, place the chopped chocolate in a heatproof bowl. Heat the cream in a small saucepan over medium heat until it simmers gently, then pour it over the chocolate. Let sit for 2–3 minutes to soften, then stir slowly until smooth. Refrigerate the ganache for at least 30 minutes to thicken before using.
Step 8: Prepare the whipped vanilla buttercream by beating the softened butter with a mixer on medium speed until creamy, about 2 minutes. Add confectioners’ sugar, heavy cream, and vanilla extract. Beat on low for 30 seconds, then increase to medium-high and beat for 3 minutes until fluffy. Adjust consistency with extra sugar or cream if needed, and add a pinch of salt to balance sweetness.
Step 9: Using a sharp knife, cut a 1-inch deep circle in the center of each cooled cupcake to create a pocket. Remove the cut piece, tear off its pointed end, and fill the pocket with 1–2 teaspoons of the buttercream using a spoon or piping tip.
Step 10: Press the trimmed cupcake piece back on top of the filling to close it.
Step 11: Spread a thick layer of the chilled ganache over each cupcake to create a fudge-like topping.
Step 12: (Optional) Pipe a swirl or design of remaining buttercream on top of the ganache using a piping bag and your preferred tip.
Step 13: Serve immediately, or store covered at room temperature or refrigerated for up to 1 day before serving.

Tips & Variations

Use hot coffee instead of water to enhance the chocolate flavor in the cupcakes.
If you don’t have buttermilk, mix 1/2 cup milk with 1/2 teaspoon lemon juice or vinegar and let it sit for 5 minutes as a substitute.
For a different filling, try cream cheese frosting or flavored buttercreams like mocha or raspberry.
Make sure cupcakes are fully cooled before filling to prevent the buttercream from melting.
Finely chop the chocolate for ganache to ensure it melts smoothly and quickly.

Storage

Store the cupcakes covered at room temperature or in the refrigerator for up to one day if decorated. For longer storage, keep leftover cupcakes refrigerated for up to three days. To maintain their shape and decoration, using a cupcake carrier is recommended. If refrigerated, bring cupcakes to room temperature before serving for the best texture and flavor.

How to Serve

The image shows a close-up of four chocolate cupcakes on a wooden stand with a dark bark edge. Each cupcake has a rich, dark brown cake base with a smooth layer of shiny dark chocolate ganache on top. The ganache is decorated with a white icing design that looks like a cross or plus sign. One cupcake in front is cut open, revealing a thick cream-colored filling inside the moist, dark chocolate cake. The background is a white marbled texture, and there is a soft pink cloth slightly blurred underneath the stand. Photo taken with an iphone --ar 4:5 --v 7

FAQs

Can I use regular milk instead of buttermilk?

Yes, you can substitute buttermilk by adding 1/2 teaspoon lemon juice or vinegar to 1/2 cup milk. Let it sit for 5 minutes to curdle, then use it as buttermilk in the recipe.

How do I prevent the cupcakes from falling apart when filling?

Make sure the cupcakes are completely cooled or lightly chilled before cutting and filling. Also, remove the pointed end of the cut-out cupcake piece so it rests flush and seals the filling inside, which helps prevent crumbling.
