Introduction

These cream-filled chocolate cupcakes combine rich, moist chocolate cake with a fluffy vanilla buttercream center and a smooth ganache topping. Perfect for celebrations or any time you want a decadent treat that’s sure to impress.

The image shows six chocolate cupcakes on a white marbled textured surface, five whole and one cut in half to reveal the inside. Each cupcake has a thick layer of dark chocolate frosting on top with a smooth, swirled texture. On top of each frosting, there is a white zigzag line made of a creamy frosting. The cut cupcake reveals three layers visually: the outer dark chocolate cake, a middle layer of white creamy filling, and a thin chocolate frosting layer on top. The cupcakes sit closely together and the cupcake paper liners are slightly crinkled with brown spots. 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 the oven to 350°F (177°C). Line a 12-count muffin pan with cupcake liners. This recipe makes about 15 cupcakes, so line a second pan with 3 liners or plan to bake in two 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, and buttermilk until combined. Pour the wet ingredients into the dry ingredients, add the hot coffee or hot 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 prevent spills. You should have enough batter for 15 cupcakes.
Step 5: Bake for 20–22 minutes, or until a toothpick inserted in the center comes out clean. Let the cupcakes cool in the pan for 10 minutes, then transfer to a wire rack to cool completely. Chill them 20–30 minutes in the refrigerator if tops feel sticky.
Step 6: To make ganache, place the chopped chocolate in a medium heatproof bowl. Heat the heavy cream in a saucepan over medium heat until it just begins to simmer. Pour the hot cream over the chocolate and let sit 2–3 minutes. Stir gently until smooth. Refrigerate for at least 30 minutes to thicken.

Step 7: For the buttercream filling, beat softened butter on medium speed with a mixer until creamy, about 2 minutes. Add confectioners’ sugar, heavy cream, and vanilla. Beat on low for 30 seconds, then on medium-high for 3 minutes. Adjust consistency by adding more sugar if too thin or more cream if too thick. Add a tiny pinch of salt if too sweet. Frosting should be fluffy.
Step 8: Use a sharp knife to cut a 1-inch deep circle from the center of each cooled cupcake, removing the cone-shaped piece. Fill the hole with whipped buttercream—about 1–2 teaspoons. Trim the pointy end of the removed piece and gently press it back on top of the filling.
Step 9: Spread a thick layer of chilled ganache over each cupcake to create a fudge-like topping.

Step 10: (Optional) Pipe a swirl or loop design on top of the ganache with the remaining vanilla buttercream. No need to chill beforehand. Use a piping tip if available.
Step 11: Serve immediately or cover and store at room temperature or refrigerated for up to 1 day before serving. Leftover cupcakes keep in the fridge for up to 3 days.

Tips & Variations

Use hot coffee instead of water to deepen the chocolate flavor of the cupcakes.

For a dairy-free version, substitute coconut cream for heavy cream and use plant-based butter.
Chop the chocolate finely for faster melting and a smoother ganache.
If frosting is too sweet, a tiny pinch of salt balances the flavor beautifully.

For easier filling, use a piping bag or a teaspoon measuring spoon.

Storage

Store cupcakes covered at room temperature for up to 1 day or refrigerate for up to 3 days. If refrigerated, let them come to room temperature before serving for the best flavor and texture. Use a cupcake carrier or airtight container to protect decorations and prevent drying out.

How to Serve

The image shows a close-up of four chocolate cupcakes placed on a round wooden stand with tree bark edges. Each cupcake has three visible layers: a dark, moist chocolate cake base, a thick layer of dark chocolate ganache on top, and white cream cheese frosting piped in a football lace pattern on the ganache. One cupcake at the front is bitten into, revealing the dark chocolate cake surrounding a creamy white filling inside. The background is a white marbled texture with a slightly blurry soft pink cloth visible at the bottom. photo taken with an iphone --ar 4:5 --v 7

FAQs

Can I make these cupcakes dairy-free?

Yes, substitute the heavy cream with coconut cream and use a dairy-free butter alternative for the buttercream. Use non-dairy milk as a buttermilk substitute, mixed with a little vinegar or lemon juice.

How do I stop the ganache from being too runny?

Allow the ganache to chill in the refrigerator for at least 30 minutes until it thickens to a spreadable consistency. Stir occasionally while cooling to ensure an even texture. Avoid overheating the cream to prevent separation.
