Ingredients
Chocolate Cake
- 1½ cups all-purpose flour
- ½ cup cocoa powder (use high-quality for best results)
- 1 cup sugar
- 1 tsp baking powder
- 1 tsp baking soda
- ½ tsp salt
- 2 eggs
- ½ cup milk
- ½ cup vegetable oil
- 1 tsp vanilla extract
- ½ cup hot coffee (enhances chocolate flavor)
Chocolate Cream
- 200 g dark or semi-sweet chocolate
- 1 cup heavy cream
- 2 tbsp powdered sugar
Chocolate Ganache
- 150 g dark chocolate
- ¾ cup heavy cream
- 1 tbsp butter
Caramelized Walnuts
- 1 cup walnuts
- ¼ cup sugar
- 1 tbsp butter
Optional substitutions:
- Replace all-purpose flour with gluten-free flour blend for dietary needs.
- Use coconut milk and dairy-free chocolate for a vegan version.
Step-by-Step Instructions
-
Preheat your oven to 175°C (350°F). Grease and line a cake pan with parchment paper for easy removal.
-
In a large bowl, whisk together the dry ingredients: flour, cocoa powder, sugar, baking powder, baking soda, and salt.
-
Add eggs, milk, vegetable oil, and vanilla extract. Mix until smooth and well combined.
-
Gradually pour in the hot coffee while stirring. The batter will become thin—this ensures a moist chocolate walnut cake.
-
Pour the batter into the prepared pan and bake for 30–35 minutes. A toothpick inserted should come out clean. Let the cake cool completely before assembling.
-
For the chocolate cream, gently melt chocolate with heavy cream using a double boiler. Let it cool slightly, then whip until creamy and spreadable.
-
Carefully slice the cooled cake horizontally into two or three layers. Spread the chocolate cream evenly between each layer.
-
To caramelize the walnuts, heat sugar and butter in a pan over medium heat until melted. Add walnuts, stirring until coated and golden. Let them cool before breaking into pieces.
-
Prepare the ganache by pouring hot cream over chopped chocolate. Stir until smooth, then add butter for extra shine.
-
Pour the ganache over the assembled cake, letting it drip down the sides. Top with caramelized walnuts and an optional chocolate drizzle.
-
Refrigerate for at least 1–2 hours before slicing to allow the layers to set.

Serving Suggestions
Pair this chocolate walnut cake with:
- A scoop of vanilla ice cream
- Fresh berries for contrast
- A warm cup of espresso or cold milk
Common Mistakes to Avoid
- Overmixing the batter can lead to a dense cake. Mix just until combined.
- Adding ganache to a warm cake will cause it to melt unevenly—always let the cake cool first.
- Skipping the coffee may result in a less intense chocolate flavor.
Storage Tips
- Refrigerate leftovers in an airtight container for up to 5 days.
- Freeze individual slices wrapped in plastic for up to 3 months. Thaw in the fridge before serving.
- Avoid storing at room temperature for long periods due to the cream filling.
