Dark, moist chocolate cupcakes filled with rich chocolate ganache and finished with a smooth, generous spiral of vanilla buttercream. These Chocolate Ganache Cupcakes from Coal & Crumb are made for chocolate lovers, with a deep cocoa flavor, a soft crumb, and a hidden ganache center in every bite.
This recipe makes 24 consistent cupcakes using a simple production flow: bake, cool, prepare the ganache, fill, and finish with buttercream. Whether you're baking for a celebration, sharing with friends, or stocking the dessert table, this method keeps the process organized and the results consistent from the first cupcake to the last.
The secret to the chocolate flavor is hot coffee. Added at the end of mixing, it deepens the cocoa without making the cupcakes taste like coffee. The batter will be surprisingly thin, but that's exactly what gives these cupcakes their dark, tender crumb.
The second key is the ganache. Let it cool until it reaches a thick, peanut-butter-like consistency before piping it into the cupcakes. It should hold its shape inside the center rather than run out when you take a bite.

Ingredients
Chocolate Cupcakes
200 g cake flour
300 g granulated sugar
75 g cocoa powder
10 g baking soda (about 2 teaspoons)
1 teaspoon baking powder
1 teaspoon fine salt
2 large eggs
240 g whole milk
120 g neutral oil
2 teaspoons vanilla extract
240 g hot coffee
Chocolate Ganache Filling
300 g dark chocolate, finely chopped
300 g heavy cream
Vanilla Buttercream
300 g unsalted butter, softened to room temperature
450 g powdered sugar
30–50 g heavy cream, as needed
Vanilla extract, to taste
A pinch of fine salt
How to Make Chocolate Ganache Cupcakes
1. Prepare the chocolate cupcake batter
Preheat the oven to 175°C (350°F) and line two standard muffin pans with 24 cupcake liners.
In a large mixing bowl, whisk together the cake flour, sugar, cocoa powder, baking soda, baking powder, and salt until evenly combined.
Add the eggs, milk, oil, and vanilla extract. Mix until the batter is smooth and no dry ingredients remain.
Slowly pour in the hot coffee while mixing. The batter will become thin and pourable. Don't be tempted to add more flour; this consistency is intentional and helps create the moist chocolate crumb.
2. Portion and bake
Divide the batter evenly between the cupcake liners, filling each about one-half to two-thirds full. Using a scoop or portioning tool helps keep all 24 cupcakes uniform.
Bake for 18–22 minutes, rotating the pans halfway through if needed. Check doneness with a toothpick inserted into the center; it should come out with a few moist crumbs but no wet batter.
For a large batch, check the first tray carefully before baking the remaining cupcakes. Oven differences can affect the final bake time.
3. Cool completely
Allow the cupcakes to rest in the pans for 10–15 minutes before transferring them to a wire rack.
Let them cool completely before filling or frosting. Warm cupcakes can melt the ganache and buttercream, making the finishing process much harder.
4. Make the chocolate ganache
Place the chopped dark chocolate in a heatproof bowl.
Heat the heavy cream in a saucepan until steaming and just beginning to simmer around the edges. Pour it over the chocolate and let it sit for 1–2 minutes.
Stir gently from the center outward until the chocolate and cream form a smooth, glossy ganache.
Allow the ganache to cool until thick and pipeable, similar to peanut butter. If it is too warm, it will run out of the cupcakes. If it becomes too firm, gently warm it until it softens enough to pipe.
5. Core and fill the cupcakes
Once the cupcakes are completely cool, use a small knife or cupcake corer to remove a shallow section from the center of each cupcake.
Pipe the cooled ganache into each opening, stopping just below the top of the cupcake.
Avoid coring too deeply or overfilling. A shallow, controlled center keeps the filling inside while leaving enough cupcake around it to support the frosting.
6. Prepare the vanilla buttercream
Beat the softened butter until smooth and creamy.
Gradually add the powdered sugar, mixing on low speed at first to prevent a cloud of sugar from escaping the bowl.
Add the vanilla extract and a pinch of salt. Pour in the heavy cream a little at a time until the buttercream reaches a smooth, light consistency that holds its shape.
Beat until fluffy, then transfer to a piping bag fitted with your preferred decorating tip.
7. Pipe and finish
Pipe a consistent spiral of buttercream onto each filled cupcake.
For a simple, classic finish, leave the buttercream as it is. For an extra chocolate touch, add a drizzle of melted chocolate or a light scattering of chocolate shavings.
The finished cupcakes should have a dark chocolate base, a rich ganache center, and a clean buttercream spiral.
Baker's Notes
Check the first tray before committing the whole batch. Bake a test tray and evaluate the crumb, moisture, and doneness. Adjust the remaining bake time if needed. That quick quality check can save an entire batch.
Prevent sticking liners. Use quality cupcake liners designed for baking. If sticking has been an issue, lightly spray the liners before filling. Let cupcakes cool completely before peeling; a short chill can also help if the liners still grab.
Keep the ganache at the right consistency. It should be thick enough to pipe and hold its shape. If it's runny, give it more time to cool.
Keep the cupcake centers shallow. Removing too much cake can cause the ganache to leak through the bottom. A small, controlled opening is all you need.
Make the components ahead. The cupcakes can be baked and cooled ahead of time, and the ganache can be prepared while they cool. Assemble once everything has reached the right consistency.
Storage
Store filled and frosted Chocolate Ganache Cupcakes in an airtight container at room temperature for up to 1 day, or refrigerate for up to 4 days.
For the best texture and flavor, allow refrigerated cupcakes to sit at room temperature for about 30 minutes before serving. This softens the buttercream and lets the ganache become creamy again.
-
Yes. Replace the hot coffee with hot water. The cupcakes will still be moist and chocolatey, though coffee helps deepen the cocoa flavor.
-
Dark chocolate works best for a rich filling that balances the sweet buttercream. Semi-sweet chocolate can also be used. If using a sweeter chocolate, expect a sweeter ganache.
-
It should be thick and spreadable, similar to peanut butter. It should hold its shape when piped without running into the cupcake.
-
Yes. Bake the cupcakes a day ahead and store them airtight once completely cool. Prepare the ganache and buttercream, then fill and frost closer to serving for the freshest finish.
