Ingredients

Chocolate Cake

• 1½ cups all-purpose flour
• ¾ cup cocoa powder (use high-quality for best results)
• 1 cup sugar
• 1 tsp baking soda
• ½ tsp baking powder
• ½ tsp salt
• 2 eggs
• ½ cup milk
• ½ cup vegetable oil
• 1 tsp vanilla extract
• ¾ cup hot coffee (enhances chocolate flavor)

Molten Chocolate Filling

• 200 g milk chocolate (or dark chocolate for a richer taste)
• 150 ml heavy cream
• 3 tbsp Nutella

Chocolate Crunch Topping

• 200 g milk chocolate
• 1 cup chopped chocolate pieces (chocolate bars or chocolate chips work well)
• ½ cup crushed chocolate cookies

Ingredient Tips

• For a gluten-free version, swap all-purpose flour with almond flour or gluten-free baking mix.
• Substitute heavy cream with coconut cream for a dairy-free option.
• If you don’t have Nutella, peanut butter or caramel sauce can add a delicious twist.

Step-by-Step Instructions

1. Preheat your oven to 175°C / 350°F. Line a cake pan with parchment paper for easy removal.

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

3. Add eggs, milk, vegetable oil, and vanilla extract. Mix until smooth and free of lumps.

4. Slowly pour in the hot coffee while stirring continuously. The batter will be thin—this is normal.

5. Pour the batter into the prepared pan and bake for 25–30 minutes. A toothpick inserted should come out mostly clean.

6. Let the cake cool completely before handling. This prevents crumbling when slicing into layers.

7. For the molten filling, heat the heavy cream until warm (not boiling), then pour over the chopped chocolate. Stir until melted and glossy. Add Nutella and mix well.

8. Slice the cake horizontally into two or three layers. Spread a generous amount of the chocolate filling between each layer.

9. Stack the layers back together and cover the entire cake with the remaining chocolate mixture.

10. Press chopped chocolate pieces and crushed cookies onto the top and sides for maximum crunch.

11. Chill the cake in the refrigerator for at least 30 minutes to set. Before serving, let it sit at room temperature for 10 minutes to soften slightly.

12. Slice into the cake to reveal the molten chocolate center—pure bliss!

Common Mistakes to Avoid

• Overbaking the cake—this dries it out and reduces the molten effect.
• Using cold cream for the filling—it may cause the chocolate to seize.
• Skipping the chilling step—the cake needs time to set before serving.
• Not slicing evenly—uneven layers make assembly difficult.

Storage Tips

• Refrigeration: Store in an airtight container for up to 3 days.
• Freezing: Wrap tightly in plastic wrap and freeze for up to 1 month. Thaw overnight in the fridge before serving.
• Reheating: Warm individual slices in the microwave for 10–15 seconds to revive the molten center.
