If you love coffee and chocolate, you must try this Kahlua Chocolate Cake! A rich chocolate cake, soaked with a Kahlua syrup and topped with Kahlua whipped cream. It makes for an impressive yet simple dessert, with coffee and chocolate in every bite.
I got the idea for this cake one evening while enjoying some Tiramisu. Tiramisu consists of ladyfingers dipped in espresso (sometimes spiked with a liqueur), and layered with a lightly sweetened mascarpone cream. I’m familiar with poke cakes, where you literally poke small holes all over a warm cake with a wooden skewer, then pour over a condensed milk mixture. For this cake, I knew I wanted it to be chocolate but I didn’t want to use condensed milk. So, similar to tiramisu, I used both espresso and Kahlua (coffee liqueur) in a simple syrup which I then poured on the cake. To amp up the Kahlua flavor even more I made a Kahlua whipped cream. Once the cake was completely cool I piped on the cream and garnished it with some shaved dark chocolate. Pure adult decadence!
Ingredients for Kahlua Chocolate Cake:
- Kahlua
- Espresso powder. You can also use regular instant coffee but the coffee flavor won’t be as pronounced.
- Unsweetened cocoa powder
- Heavy cream
- Granulated sugar
- All-purpose flour
- Baking soda & baking powder
- 1 large egg
- Vegetable oil
- Salt
- Buttermilk (see note below)
- Vanilla extract
- Powdered sugar
- Dark chocolate for grating
Make your own buttermilk:
If you don’t have buttermilk, it’s easy to make your own. Simply measure a scant 1 cup of regular milk and add 1 tablespoon of white vinegar or lemon juice. Leave it to sit on the counter for 10 minutes, then it’s ready to use.
How to make Kahlua Chocolate Cake:
First, make the chocolate cake. This cake is great because it all comes together in one bowl, and vegetable oil replaces the butter.
While the cake is baking, make the Kahlua simple syrup. Do not skip the syrup! It makes the cake ultra moist and flavorful. Equal amounts of sugar and water plus espresso powder are put in a small saucepan and brought to a gentle boil. After one minute, the sugar should be completely dissolved. Once done, take the syrup off the heat and stir in the Kahlua. Set aside until needed.
Once the cake is done baking, place it on a cooling rack for 10 minutes. Set a timer, as you don’t want it cooling for any longer before you pour the syrup over it. After the 10 minutes, invert the cake onto a serving platter or plate (if you have one with sides this is ideal, but not essential). Using a wooden (bamboo) skewer, poke holes all over the cake. Then pour the syrup over the warm cake. Set cake aside to cool completely.
Once the cake is cool, and right before serving, make the Kahlua whipped cream: in a large mixing bowl or the bowl of stand mixer, beat the heavy cream, powdered sugar and Kahlua on medium-high speed until stiff peaks form. Pipe or spread cream onto the top of the cake and garnish with shaved dark chocolate.

Ingredients
For the cake:
- 1 cup all-purpose flour
- 1 cup granulated sugar
- ½ cup unsweetened cocoa powder
- 1 teaspoon baking soda
- ½ teaspoon baking powder
- ¼ teaspoon salt
- 1 large egg
- ½ cup vegetable oil
- ½ cup buttermilk

Instructions
Make the chocolate cake:
- Spray an 8×8 inch square baking pan with cooking spray. Set aside. Preheat the oven to 350°F (176°C).
- In a large bowl, sift the flour, baking soda, baking powder and cocoa powder. Whisk in the sugar and salt.
- Add egg, oil, buttermilk and vanilla and whisk until combined. Add hot coffee and whisk until batter is smooth. It will be runny. Pour into prepared pan. Bake for 25 to 30 minutes or until a toothpick inserted into the centre comes out clean. Place on a cooling rack for 10 minutes. While the cake is baking, make the syrup:
Make the Kahlua syrup:
- Bring sugar, water and espresso powder to a boil in a small saucepan over medium-high heat. Simmer for 1 minute. The sugar should be completely dissolved. Remove from heat and stir in Kahlua. Set aside.
Soak the cake:
- Once the cake has cooled for 10 minutes, transfer it to a serving plate or platter. Using a wooden skewer, poke holes all over the cake. Take the syrup and pour it over the cake, so it soaks into all the tiny holes. Set cake aside to cool completely.
Make the Kahlua whipped cream:
- Combine the cream, sifted powdered sugar and Kahlua in a large mixing bowl or stand mixer. Beat on medium-high speed until stiff peaks form.
- Spread cream over top of cake or pipe it on using a piping bag and tip of choice. Finish with grated dark chocolate, cut into pieces and serve.
Notes
- Make sure to sift the dry ingredients, especially the cocoa powder. This will ensure there aren’t any lumps and makes for a lighter cake.
- Keep any leftovers refrigerated for up to 2 days.
