Directions
<ol class="no-list-style"><li class="MethodStepper"><h4 class="step-title">Step 1</h4>Preheat your oven to 180°C (160°C fan). Grease and line three 20cm round cake tins with parchment paper. This recipe creates three layers for an impressive height, but you can bake in batches if you only have one or two tins.</li><li class="MethodStepper"><h4 class="step-title">Step 2</h4>In a small bowl, dissolve 2 tablespoons of instant espresso powder in the 100ml of warm milk, then set aside to cool. This creates a concentrated coffee flavor that will infuse the entire cake.</li><li class="MethodStepper"><h4 class="step-title">Step 3</h4>In a large mixing bowl, cream together the butter and caster sugar until pale and fluffy, about 3-5 minutes. The extended beating incorporates air, creating a lighter texture and helping the cake rise properly during baking.</li><li class="MethodStepper"><h4 class="step-title">Step 4</h4>Add the eggs one at a time, beating well after each addition. If the mixture begins to curdle, add a tablespoon of the flour to stabilize the emulsion. This gradual incorporation ensures a smooth, stable batter.</li><li class="MethodStepper"><h4 class="step-title">Step 5</h4>Sift together the flour, cocoa powder, and baking powder, then gently fold into the butter mixture using a large metal spoon or silicone spatula. Folding rather than stirring preserves the air bubbles you've worked to incorporate.</li><li class="MethodStepper"><h4 class="step-title">Step 6</h4>Pour in the cooled espresso milk and fold until just combined. The batter should be smooth and dropping consistency - not too thick or too runny. Be careful not to overmix as this can develop the gluten and result in a tough cake.</li><li class="MethodStepper"><h4 class="step-title">Step 7</h4>Divide the batter equally between the three prepared tins (about 450g per tin if you want to be precise). Level the surfaces gently with an offset spatula. Bake in the preheated oven for 22-25 minutes, or until a skewer inserted into the center comes out clean and the cakes spring back when lightly pressed.</li><li class="MethodStepper"><h4 class="step-title">Step 8</h4>While the cakes are baking, prepare the coffee syrup. In a small saucepan, combine the freshly brewed espresso and sugar. Heat gently until the sugar completely dissolves. Remove from heat and stir in the coffee liqueur and vodka. Allow to cool completely. The alcohol in this syrup won't be cooked off, giving your cake that authentic espresso martini kick.</li><li class="MethodStepper"><h4 class="step-title">Step 9</h4>Once baked, leave the cakes in their tins for 10 minutes before turning out onto a wire rack. While still warm (but not hot), use a pastry brush to generously soak each cake with the coffee syrup. The warm cakes will absorb the syrup more effectively. Allow the cakes to cool completely before frosting.</li><li class="MethodStepper"><h4 class="step-title">Step 10</h4>For the mascarpone frosting, beat the mascarpone cheese in a large bowl until smooth. Carefully fold in the sifted icing sugar, dissolved espresso, and coffee liqueur until just combined. Avoid overmixing mascarpone as it can become runny - gentle folding is key to maintaining its luxurious texture.</li><li class="MethodStepper"><h4 class="step-title">Step 11</h4>To assemble, place the first soaked cake layer on your serving plate. Spread a generous layer of mascarpone frosting over the top, then add the second cake layer and repeat. Place the final cake layer on top.</li><li class="MethodStepper"><h4 class="step-title">Step 12</h4>Cover the entire cake with the remaining mascarpone frosting, creating a smooth finish on the sides and top. For the most professional look, apply a thin crumb coat first, chill for 20 minutes, then apply the final frosting layer.</li><li class="MethodStepper"><h4 class="step-title">Step 13</h4>Decorate the cake by pressing chocolate shavings around the sides and dusting the top with cocoa powder. If desired, arrange coffee beans and gold sprinkles artfully on top to mimic the sophisticated look of an espresso martini cocktail.</li><li class="MethodStepper"><h4 class="step-title">Step 14</h4>Refrigerate the cake for at least 2 hours before serving to allow the flavors to meld and the frosting to set. For the best flavor, remove from the refrigerator 30 minutes before serving to take the chill off. This cake will keep for up to 3 days in an airtight container in the refrigerator.</li></ol>
Chef’s Notes
A few helpful details for making this recipe.
Can I make this cake entirely non-alcoholic but still retain the espresso martini flavour?
Yes! Replace the coffee liqueur with alcohol-free coffee syrup and omit the vodka. Intensify the coffee flavour by using stronger espresso in the syrup and adding a splash of vanilla extract to mimic the depth that alcohol would provide. The cake will still have that distinctive espresso martini character.
How far in advance can I prepare this coffee-based cake for a special occasion?
You can bake the sponges up to 2 days ahead and store them wrapped in cling film. The coffee syrup can be made 3 days ahead. However, the mascarpone frosting should be prepared on the day of assembly. Once decorated, the cake keeps beautifully in the fridge for up to 3 days.
What's the secret to getting a smooth, professional-looking mascarpone frosting?
The key is temperature and technique. Ensure your mascarpone is at room temperature but not too warm. Fold rather than vigorously mix the ingredients to avoid over-beating, which can cause the mascarpone to split. Apply a thin crumb coat first, chill, then add the final layer for a polished finish.
