– 200g dark chocolate (70% cocoa solids) – 200g unsalted butter – 200g caster sugar – 4 large egg – 200g all-purpose flour – 1 tsp baking powder – 1/4 tsp salt – 1 tsp vanilla extract – 150g milk chocolate, chopped into small piece – Optional: edible decorations for garnish (e.g., chocolate shavings, berries)

Step 1: Preparing the Chocolate Batter

1. Preheat your oven to 180°C (350°F) and grease a round 9-inch cake tin. 2. In a heatproof bowl, break the dark chocolate into small pieces and add the butter. Place the bowl over a pan of simmering water, making sure the bottom of the bowl doesn't touch the water. 3. Stir the chocolate and butter until melted and well combined. Remove from heat and set aside to cool slightly.

Step 2: Mixing the Cake Batter

1. In  a separate large bowl, whisk together the caster sugar and eggs until light and fluffy. 2. Slowly pour the cooled chocolate mixture into the egg mixture, whisking continuously. 3. Sift the flour, baking powder, and salt into the bowl with the chocolate mixture. Add the vanilla extract as well. 4. Gently fold the dry ingredients into the wet mixture until just combined. Be careful not to overmix. 5. Stir in the chopped milk chocolate pieces, distributing them evenly throughout the batter.

Step 3: Baking the Gateau

1. Pour the batter into the prepared cake tin, ensuring it is spread evenly. 2. Place the tin in the preheated oven and bake for approximately 30-35 minutes or until a toothpick inserted into the center comes out with a few moist crumbs. 3. Once baked, remove the gateau from the oven and let it cool in the tin for 10 minutes. Then, transfer it to a wire rack to cool completely.

Step 4: Assembling and Decorating

1. Once the gateau has cooled, you can unleash its explosive surprise. Carefully cut a hole in the center of the cake, creating a cavity for the filling. Remove the cut-out piece, setting it aside for later. 2. Fill the cavity with your desired surprise, such as fresh berries, caramel sauce, or even a hidden scoop of ice cream. Replace the cut-out piece on top of the filling. 3. If desired, decorate the cake with edible garnishes, such as chocolate shavings or fresh berries. Let your creativity shine!

Step 5: Serving and Enjoying

1. Slice the Explosive Chocolate Gateau into generous portions and serve it on individual plates or dessert dishes. 2. Watch as your guests' eyes light up when they discover the surprise inside the cake. 3. Enjoy this decadent dessert, savoring the rich chocolate flavors and the magical moment of unlocking Heston's masterpiece.
