These super moist chocolate ganache cupcakes from scratch are soft, rich, and deeply chocolatey, with a smooth milk chocolate ganache frosting on top. The hot coffee helps bring out the cocoa flavor and keeps the cupcakes tender.
Preheat the ovenPreheat the oven to 180°C and line a 12-cup cupcake tray with paper liners.
Mix the dry ingredients In a large bowl, whisk together the flour, sugar, cocoa powder, baking soda, baking powder, and salt.
Add the wet ingredientsAdd the egg, milk, melted butter, and vanilla extract. Mix until smooth and combined.
Add the hot coffeeSlowly pour in the hot coffee while mixing. The batter will be thin, which helps make the cupcakes soft and moist.
Fill the cupcake linersDivide the batter evenly between the cupcake liners, filling each about two-thirds full.
BakeBake for 18–20 minutes, or until a toothpick inserted into the center comes out clean.
CoolLet the cupcakes cool in the pan for a few minutes, then transfer them to a wire rack to cool completely before adding the ganache.
Make the Chocolate Ganache
Melt the ganache ingredientsAdd the chopped milk chocolate, heavy cream, and butter to a microwave-safe bowl.
Microwave and stirMicrowave in 20–30 second intervals, stirring well after each one, until the chocolate melts and the ganache is smooth and glossy.
Let it thickenLeave the ganache at room temperature for 30–45 minutes, stirring occasionally, until it becomes soft and spreadable.
Optional: whip the ganacheFor a lighter, bakery-style frosting, whip the thickened ganache briefly until it looks airy and pipeable.
Frost the Cupcakes
Pipe or spread the ganacheOnce the cupcakes are completely cool, transfer the ganache to a piping bag fitted with a large star tip and pipe swirls on top. You can also spread the ganache with a spoon or spatula.
Decorate with chocolate chips or colorful sprinkles depending on the occasion.
Notes
The cupcake batter will look thin after adding the hot coffee. This is normal and helps create a moist crumb.
The coffee does not make the cupcakes taste like coffee. It deepens the chocolate flavor.
Hot water can be used instead of coffee.
Make sure the cupcakes are completely cool before frosting, or the ganache may melt.
If the ganache is too soft to pipe, let it sit longer at room temperature.
If the ganache becomes too firm, warm it for a few seconds and stir until smooth again.
Storage
Store the cupcakes in an airtight container at room temperature for 2–3 days.You can also refrigerate them for up to 5 days. Let chilled cupcakes sit at room temperature before serving so the ganache softens again.
