Espresso Cake Ingredients
- Espresso - This recipe uses both brewed espresso and espresso powder. If you don't have an espresso machine, you can make this recipe with just espresso powder.
- Kahlua - This is used in the ganache and the espresso cake soak. You can leave the alcohol out if you'd prefer.
- Chocolate - For a rich chocolate flavour, use quality dark chocolate. I used Lindt 78%.
- Flour - Use self-raising flour for this recipe.
- Sugar - This recipe uses two types of sugar: granulated white sugar in the cake layers and ganache, and caster sugar in the meringue frosting.

Instructions for Espresso Martini Cake
There are three parts to making this espresso coffee cake recipe. First, bake and chill the chocolate coffee cake layers. Then, make the espresso cake filling. Finally, prepare the Swiss meringue espresso buttercream and assemble the cake.
Espresso Coffee Cake Layers
STEP 1: Preheat the oven. Preheat the oven to 180°C (350°F) and line 3 x 22cm (9 inches) round cake tins with oil and parchment paper.
STEP 2: Cream butter, sugar, and oil. Add the oil, butter, and sugar to a bowl of a stand mixer fitted with a paddle attachment. Beat at medium to high speed until light and fluffy, for about 4 minutes.
STEP 3: Add the whole eggs. Add the eggs to the butter and sugar mixture one at a time. Beat well between each addition, scraping down the sides of the bowl often.
STEP 4: Add dry ingredients. Into a large bowl, sift together the salt, cocoa, and self-raising flour, then add the flour mixture to the egg and sugar mixture. Beat at low speed until just combined.
STEP 5: Add wet ingredients. Add the sour cream, warm coffee, and vanilla extract to a jug and whisk to combine., Slowly pour this into the cake mixture with the mixer's motor running at low speed. Scrape down the sides of the bowl and mix again, making sure it is lump-free.
STEP 6: Bake. Divide the cake batter between the two prepared pans and bake in a preheated oven for 30 minutes or until a cake tester inserted into the center of the cake comes out clean.
STEP 7: Cool. Allow the cakes to cool in their tins for 20 minutes before turning them onto a wire rack to cool completely.
Espresso Ganache Filling
STEP 1: Prepare. Add the chopped dark chocolate, cubed butter, vanilla, and salt to a heatproof bowl.
STEP 2: Heat. Add the cream and sugar to a saucepan and heat until the sugar has melted and the mixture is just simmering. Remove from the heat and whisk in the espresso powder and Kahlua.
STEP 3: Combine. Pour the heated cream mixture over the chopped chocolate. Allow the mixture to stand for a minute or two.
STEP 4: Mix. Use a spatula to mix the ganache until the chocolate and butter have melted and the ganache is fully combined. Set aside to cool and thicken, mixing every 15 minutes.
Espresso Buttercream
STEP 1: Heat. Add the egg whites and caster sugar to a heatproof bowl set over a saucepan of simmering water. Whisk continuously until the sugar has melted and the mixture is warm to the touch. Transfer the mixture to the bowl of a stand mixer.
STEP 2: Beat. Using a whisk attachment, beat the egg and sugar mixture for about 10 minutes at medium-high speed until the mixture is white and glossy with stiff peaks.
STEP 3: Add butter. Using a paddle attachment, beat the mixture at medium speed. Add the cubed butter one block at a time. Once added, increase the speed of the mixture to medium-high and continue mixing until a smooth buttercream forms, about 5 minutes.
STEP 4: Add coffee. Dissolve the espresso powder in the boiling water. With the mixer running at medium speed, add the coffee mixture to the espresso buttercream one teaspoon at a time. Once added, continue mixing until the frosting is light and fluffy. Add the frosting to a piping bag.
Espresso Cake Soak
STEP 1: Combine. In a small bowl, mix the Kahlua and espresso. Use a pastry brush to brush the tops of each cake layer with the soak.
Decorating
STEP 1: Layer. Secure the first cake layer onto a cake plate with some frosting. Pipe a layer of frosting over the surface of the cake and smooth this out with an offset spatula. Pipe a ring of frosting over the circumference of the cake layer and fill this with the cooled espresso ganache filling. Continue with the second cake layer.
STEP 2: Decorate. Place the third cake layer on top and swirl the remaining buttercream over the surface. Dust with cocoa powder and decorate with whole espresso beans. Slice, serve, and enjoy.
Variations
I think this espresso cake recipe is perfect, but if you aren't a fan of Swiss meringue buttercreams, try this Coffee Buttercream recipe instead. You may also decide that you'd prefer a vanilla coffee sponge over a chocolate sponge. If so, you can use this Vanilla Birthday Cake recipe and add three tablespoons of espresso powder to the milk.
If you'd like to add extra fancy toppings to this cake, make these Mini Meringues and dust them with cocoa powder, or these Condensed Milk Chocolate Truffles and roll them in cocoa instead of coconut.
Top Tip
To make this martini espresso cake stress-free, split the work over two days. On day one, prepare the moist chocolate espresso cake layers, allow them to cool, wrap them in clingfilm, and refrigerate them overnight. On day two, make the ganache and frosting, and then decorate the cake.

If you don't have an espresso machine and are deadset on making this espresso chocolate cake recipe, you still can! You can brew a batch of espresso using ground espresso beans and a French press, or you can use espresso powder mixed into boiling water.
As you add the butter to the whipped sugar and egg whites, the texture of the mixture will change. Trust the process and continue mixing. After about 5 minutes, you should have a perfectly creamy buttercream.
Store any leftover cake in an airtight container at room temperature for up to 3 days. If it is very hot, then store this cake in the fridge.
