Cardamon cake with mocha buttercream. — A layer cake recipe flavored with cardamom, frosted with Mocha Buttercream

Cardamom-infused coffee has been a traditional beverage for centuries in many countries, such as India, the Middle East, and Turkey. While I had eaten cardamom cake before, I had never made a layer cake until I received a request for one from one of my customers during my cake-decorating years.

And of course, being based in the Middle East, you can imagine that I’ve made this cake often for a few client celebrations.

Why is this the best cardamom cake?

Perfectly Balanced Flavors – The warm, aromatic spice of cardamom in the cake pairs beautifully with the rich, bold notes of mocha in the buttercream, creating a sophisticated yet comforting flavor profile.
Moist and Tender Texture – Your cake recipe delivers a soft, moist crumb that melts in the mouth, thanks to the perfect balance of wet and dry ingredients, making each bite incredibly satisfying.
Showstopping Presentation – The layers of spiced cake and velvety mocha buttercream create a visually stunning dessert that’s as impressive for celebrations as for intimate gatherings.
Versatility with a Gourmet Touch – This recipe works for any occasion, from weddings to birthdays, offering a unique twist on classic flavors. The use of cardamom and mocha elevates it to gourmet status, appealing to food lovers everywhere.

Ingredients and substitutes

Butter adds richness and moisture to the cake, creating a tender crumb that will leave your guests craving more. Make sure to use unsalted butter for this recipe, as it allows you to control the salt content and keep the flavors perfectly balanced.
Next up, we have the sweeteners – white and brown sugar. The combination of these sugars adds both sweetness and depth to the cake. White sugar provides a clean, straightforward sweetness, while brown sugar brings a touch of caramel-like flavor.
Eggs serve as the binding agent for the cake, giving it structure and moisture. They also contribute to the rich, velvety texture that will make each bite melt in your mouth.
Now, let’s talk about flour, the backbone of any cake. All-purpose flour is the go-to choice for this recipe, as it provides the right balance of gluten development and tenderness.
Yogurt adds moisture and tanginess to the cake, ensuring a moist and tender crumb. If you don’t have yogurt on hand, you can substitute it with an equal amount of sour cream or buttermilk.
Vanilla extract is a must-have ingredient, enhancing the overall flavor of the cake and complementing the aromatic cardamom spice.
Cardamom elevates the cake to a whole new level. If you can’t find cardamom, you can use a combination of cinnamon and nutmeg as a substitute, though it won’t quite capture the unique essence of cardamom.
This recipe calls for a medley of spices to further enhance the flavors. Feel free to adjust the amounts or experiment with different spices like cinnamon, ground nutmeg, or even a hint of cloves to add your touch to the cake.

Step-by-step Cardamom cake with frosting

Cake

Preheat the oven to 350℉/175℃/Gas Mark. Grease and line 3 x 8-inch round cake pans.
Dry ingredients: In a bowl, combine flour with baking powder, baking soda, and salt – set aside.
Wet ingredients: In the bowl of a stand mixer with the paddle attachment, cream the butter and sugars until light and fluffy. Add the eggs one at a time, followed by the vanilla extract.
Combine: Add the flour mixture and the yogurt in three additions. Followed by the espresso and vanilla extract. Divide the batter equally between the prepared baking pans.
Pro tip – I like to use cake strips to ensure my layer cakes bake flat.
Bake for 35 to 40 minutes or until a skewer inserted in the center comes clean. Cool in the pan for 10 minutes, then invert on a cooling rack and let cool completely. Wrap the cake in cling/plastic wrap and chill for a few hours before you decorate.

For the mocha buttercream

Add coffee and vanilla to the cold cream – mix well and set aside. Melt the chocolate in a microwave or double boiler – set aside
In the bowl of a stand mixer with the paddle attachment, cream the butter until smooth. Strain the coffee mixture, then add more cream. The mixture will curdle and become smooth again. Now, add the powdered sugar one cup at a time.
Once all the powdered sugar has been incorporated, mix on medium-high for 2 to 3 minutes more until you have a light and fluffy buttercream. The cream in the mixture will whip and give you almost stiff peaks.
Pro tip: You must whip more if the buttercream is too soft. However, if the butter melts, chill the bowl for 10 minutes, then whip it again. (This can happen in warmer temperatures)
Now, add the melted and cooled chocolate. Make sure to scrape the bottom and sides to ensure you have a smooth chocolate buttercream with no white streaks.
Pro tip – If the chocolate is not cooled, it will seize when added to the buttercream, and you will end up with small shards of chocolate in the buttercream. So, make sure the chocolate is cooled.

Assemble

Prepare simple syrup – cool completely before using.
Pro tip – Simple syrup is just sugar water that has been boiled and cooled. Used to keep cake layers moist.
Once cooled, cut the domes off the cake layers with a serrated bread knife or cake leveler. Brush each layer with simple syrup on both sides.
Pro tip – See my tutorial on how to level, torte, and fill cakes like a pro.
Place a cake layer on the cake board or cake stand. Top with about a cup of buttercream – spread evenly using a spatula. Place the second layer, more buttercream, and then the last layer. Chill in the fridge for 15 minutes.
Pro tip – Chilling the cake at this point will ensure the layers don’t move when you frost the outside. However, leaving the cake uncovered in the fridge for too long can dry it out. So, 10 minutes is all you need.
Spread the remaining buttercream around and on top of the cake. Create a rustic buttercream look by simply swirling the tip of the spatula up and down the side of the cake, creating distinct lines. Alternatively, place the remaining frosting in a piping bag with a large star piping tip, and pipe swirls on top of the cake.
I decorated with whole spices used in the cake for a rustic buttercream look.

Storage

Once decorated, the cake does not need to be refrigerated.
It can stay at room temperature for two days or in the fridge for up to 5 days.
Once cut, always cover the cut side of the cake with cling wrap or plastic wrap so it does not dry out.
The cake can be frozen for up to a month if wrapped well. Thaw in the fridge overnight for a moist cake.

Frequently asked questions

Can I make this cake ahead of time?

Yes, you can definitely make this cardamom cake ahead of time. In fact, it often tastes even better the next day, as the flavors have had time to meld. Simply bake the cake as instructed, let it cool completely, and then store it in an airtight container at room temperature overnight. If you want to make it even further in advance, you can freeze the cake for up to three months. Just be sure to wrap it tightly in plastic wrap and then place it in a freezer-safe bag or container.

How should I store the leftover cake?

If you have any leftovers (which is unlikely, but hey, it could happen), you’ll want to store the cake properly to keep it fresh. Simply place the remaining slices in an airtight container or cover them tightly with plastic wrap. You can store the cake at room temperature for up to three days or refrigerate it for up to a week. Just note that the cake may firm up slightly in the refrigerator, so be sure to let it come to room temperature before serving to enjoy its full flavor and texture.

What other frostings can I use instead of mocha buttercream?

There are so many other choices for frosting. Such as:
Swiss or Italian Meringue Buttercream
French or German Buttercream Frosting
Classic American vanilla or Chocolate Buttercream Frosting
