Ingredients

For the Cake Layers:

2 cups (250 g) all-purpose flour
2 cups (400 g) granulated sugar
¾ cup (75 g) unsweetened cocoa powder
2 tsp baking powder
1 ½ tsp baking soda
½ tsp salt
1 cup (240 ml) buttermilk, room temperature
½ cup (120 ml) vegetable oil
2 large eggs
1 tsp vanilla extract
1 cup (240 ml) hot coffee or espresso

For the Chocolate-Rum Cream:

1 ½ cups (360 ml) heavy cream
1 ½ cups (180 g) semisweet chocolate, finely chopped
3 tbsp dark rum
1 tsp vanilla extract

Optional Garnish:

Chocolate shavings
Cocoa powder
Coffee beans

Step-by-Step Instructions

1. Prepare the Cake Layers

Preheat oven to 350°F (175°C). Grease and flour two 9-inch round cake pans. Line bottoms with parchment paper.

In a large bowl, whisk together flour, sugar, cocoa powder, baking powder, baking soda, and salt.

In another bowl, combine buttermilk, oil, eggs, and vanilla. Slowly mix into the dry ingredients.

Add hot coffee gradually and mix until smooth. The batter will be thin — that’s normal.

Divide batter evenly between the prepared pans. Bake 30–35 minutes, or until a toothpick inserted in the center comes out clean.

Cool in pans for 10 minutes, then turn out onto wire racks to cool completely.

2. Make the Chocolate-Rum Cream

Heat heavy cream in a small saucepan until just simmering. Remove from heat and pour over chopped chocolate.

Let sit for 2–3 minutes, then stir until smooth and glossy.

Add rum and vanilla extract. Chill in the refrigerator for 1–2 hours until thickened but still spreadable.

3. Assemble the Cake

Place one cake layer on a serving plate. Spread a generous amount of chocolate-rum cream evenly over the top.

Place the second layer on top and frost the entire cake with the remaining cream.

Smooth with a spatula or leave slightly rustic for a homemade look.

4. Garnish and Serve

Top with chocolate shavings, cocoa dusting, or a few coffee beans for a dramatic finish.

Chill for 30 minutes before slicing for cleaner layers.

Tips for Success

Use freshly brewed strong coffee for maximum mocha flavor.
Chop chocolate finely to ensure smooth ganache.
Let cake layers cool completely before frosting to prevent melting.
For extra stability, refrigerate the cake for 15–20 minutes before slicing.
Adjust rum to taste — you can omit for a kid-friendly version.

Can be frozen for up to 2 months; thaw in the refrigerator before serving.
