- 2 tsp baking powder
- 1 1/2 tsp baking soda
- 1/2 tsp salt
- 300 g (1 1/2 cups) granulated sugar
- 2 large eggs
- 240 ml (1 cup) milk (or buttermilk for extra richness)
- 120 ml (1/2 cup) vegetable oil
- 2 tsp vanilla extract
- 240 ml (1 cup) hot coffee or hot water
For the buttercream:
- 200 g (1 cup) unsalted butter, room temperature
- 300 g (2 1/2 cups) powdered sugar
- 75 g (2/3 cup) cocoa powder
- 2–3 tbsp milk or cream
- 1 tsp vanilla extract
- Pinch of salt
For the ganache:
- 300 g (10 oz) dark chocolate, chopped
- 250 ml (1 cup) heavy cream
- 2 tbsp butter (optional)
Directions:
- Preheat oven to 175°C / 350°F. Grease and line your cake pans.
- In a large bowl, sift together flour, cocoa, baking powder, baking soda, and salt.
- In another bowl, whisk eggs, sugar, milk, oil, and vanilla until smooth.
- Gradually add the dry ingredients to the wet.
- Stir in hot coffee or water – the batter will be thin, but that’s okay!
- Divide between pans and bake for 25–30 minutes, or until a toothpick comes out clean.
- Let cool completely before assembling.
- For buttercream, beat butter until fluffy. Add powdered sugar, cocoa, salt, and vanilla. Mix. Add milk one spoon at a time until desired consistency.
- For ganache, heat cream until simmering, pour over chocolate. Let sit 2 mins, then stir until glossy. Add butter if using. Cool until spreadable.
- Level cake layers if needed and place one layer on a cake stand, spread with frosting.
- Repeat with the next layers and cover the entire cake with frosting or ganache.
- Chill before slicing for clean cuts. Optional add-ons: Fresh berries, chocolate shavings or curls, nuts, gold dust, drip glaze, or sprinkles for decoration.
Best ways to serve this cake
Serve slices at room temperature or slightly chilled. If you chilled the cake to set the frosting, let it sit 20–30 minutes at room temperature before serving so the buttercream softens and the flavor opens. Top with fresh berries or a few chocolate curls for a pretty plate.
For a family gathering, pair slices with a scoop of vanilla ice cream or a dollop of whipped cream. You can also serve smaller slices with coffee for an after-dinner treat: brownie cheesecake ideas work well as inspiration.
How to keep leftovers fresh
- Room temperature: Keep covered for up to 2 days.
- Refrigerator: Store in an airtight container for up to 5 days. Bring to room temperature before serving.
- Freezing: Wrap slices tightly in plastic and foil and freeze up to 2 months. Thaw in the fridge overnight, then bring to room temperature.
Handy tips to get this cake right
- Measure flour by spooning it into the cup and leveling — don’t pack it.
- Hot coffee deepens the chocolate flavor; use strong coffee if you want a bolder taste.
- Thin batter is normal — it gives a moist cake.
- Chill the cake 15–30 minutes after frosting to make cleaner slices.
- Use high-quality chocolate for better ganache shine and flavor.
Simple variations to try
- Mocha: Add 1–2 tsp instant espresso to the batter.
- Nutty: Fold chopped toasted hazelnuts or walnuts between the layers.
- Layer surprise: Add a thin layer of raspberry jam or chocolate ganache between cake layers.
- Lighter frosting: Use whipped chocolate cream instead of buttercream.

Frequently asked questions
Q: Can I make this cake ahead?
A: Yes. Bake layers up to 2 days ahead and wrap them in plastic. Chill or freeze. Assemble and frost the day you serve for best freshness.
Q: Can I use cocoa or chocolate substitutes?
A: You can swap Dutch-process cocoa for natural cocoa, but results vary. If you use milk instead of whole milk, the cake may be less rich.
Q: How do I fix a dry cake?
A: Brush each layer with simple syrup (equal parts sugar and water heated until sugar dissolves) before frosting to add moisture.
Q: Can I make this gluten-free?
A: Use a 1:1 gluten-free flour blend that measures like wheat flour. Texture may differ slightly.
