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

1. Preheat your oven to 175°C (350°F). Grease and line a cake pan with parchment paper for easy removal.

2. In a large bowl, whisk together the dry ingredients: flour, cocoa powder, sugar, baking powder, baking soda, and salt.

3. Add eggs, milk, vegetable oil, and vanilla extract. Mix until smooth and well combined.

4. Gradually pour in the hot coffee while stirring. The batter will become thin—this ensures a moist chocolate walnut cake.

5. 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.

6. For the chocolate cream, gently melt chocolate with heavy cream using a double boiler. Let it cool slightly, then whip until creamy and spreadable.

7. Carefully slice the cooled cake horizontally into two or three layers. Spread the chocolate cream evenly between each layer.

8. 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.

9. Prepare the ganache by pouring hot cream over chopped chocolate. Stir until smooth, then add butter for extra shine.

10. Pour the ganache over the assembled cake, letting it drip down the sides. Top with caramelized walnuts and an optional chocolate drizzle.

11. 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.
