Ingredients
For the Cake
- ½ cup plus 2 tbsp boiling hot water (155 ml)
- 4 tsp instant coffee powder
- ⅓ cup cocoa powder (30 g)
- 1⅓ cups all-purpose flour (160 g)
- 1 tsp baking powder
- ½ tsp baking soda
- ½ tsp salt (if using unsalted butter)
- 140 g butter, room temperature
- ½ cup brown sugar (105 g)
- ¾ cup caster sugar (140 g)
- 2 large eggs, room temperature
- 1½ tsp vanilla extract
- ⅓ cup plain thick yoghurt (75 g), room temperature
For the Coffee Ganache
- 100 g dark chocolate (50–60%), finely chopped
- ¾ cup whipping cream (190 ml)
- 2 tsp instant coffee powder
Ingredient Notes and Substitutions
- Instant coffee powder gives the strongest, most reliable flavor. Espresso powder works well too if that is what you have on hand.
- Plain thick yoghurt keeps the crumb moist and tender. Sour cream is a good substitute if you prefer.
- Use dark chocolate in the 50–60% range for the ganache. Anything sweeter will make the topping less balanced against the coffee flavor.
Step-by-Step Instructions
Preheat and Prepare the Pan
Preheat the oven to 160°C (320°F). Grease a 9-inch springform or round cake tin and set it aside.
Make the Coffee Mixture
Dissolve the instant coffee powder in the boiling hot water. Set it aside to cool completely while you prepare the rest of the batter.
Sift the Dry Ingredients
Sift the cocoa powder, flour, baking powder, baking soda, and salt into a large bowl. Set aside.
Cream the Butter and Sugars
In a separate bowl, beat the butter, brown sugar, and caster sugar together until pale and creamy. Add the eggs and vanilla extract, and beat until well combined.
Stabilize and Add Yoghurt
Add a few tablespoons of the flour mixture into the butter mixture to stabilize it, then beat in the yoghurt until smooth.
Combine Wet and Dry Ingredients
Alternately add the remaining flour mixture and the cooled coffee, starting and ending with the flour mixture. Fold gently until the batter is smooth and no streaks remain.
Bake the Cake
Pour the batter into the prepared tin. Bake for 1 hour to 1 hour 10 minutes, until a toothpick inserted into the center comes out clean. Cool completely in the tin at room temperature.
Make the Coffee Ganache
Heat the cream and instant coffee powder together until warm and just barely simmering. Pour it over the chopped chocolate and let it rest for 1 minute, then stir until smooth and glossy.
Chill and Thicken the Ganache
Chill the ganache for about 20 minutes, until it thickens to a spreadable, pourable consistency.
Finish the Cake
Pour the ganache over the cooled cake, smoothing it around the top and sides with an offset spatula. Let it set at room temperature before slicing.
Tips for the Best Results
- Make sure the coffee mixture is fully cooled before adding it to the batter so it does not affect the eggs or butter.
- Do not overbake. Start checking with a toothpick a few minutes before the lower end of the bake time.
- Chill the ganache just until thickened, not fully set, so it stays easy to spread and smooth.
- Bring refrigerated cake back to room temperature before serving, since butter cakes firm up in the fridge.
Variations and Add-ins
- Slice the cake in half horizontally and layer with extra ganache for a two-layer version.
- Add a handful of chopped toasted walnuts or pecans on top before the ganache sets.
- Dust with a little extra cocoa powder or top with chocolate shavings for a simple finishing touch.
- Swap the ganache for a coffee buttercream if you prefer a fluffier topping.
What to Serve With It
- A hot cup of coffee or espresso to double down on the flavor pairing
- A scoop of vanilla ice cream on the side
- Fresh whipped cream for a lighter finish
- A dusting of powdered sugar for a simple presentation
