The Internet's Most Famous Crunchy Chocolate Cake

In a bowl, vigorously mix the egg, sugar, oil, half of the milk, and warm water using a whisk.

Incorporate the all-purpose flour, alternating with the cocoa powder, until the batter is smooth.

Add the vanilla extract and baking powder, mixing gently to combine everything and lighten the batter.

Pour the batter into a greased pan and bake until done.

While the cake bakes, prepare the soaking syrup by boiling the remaining milk with the cocoa powder.

After removing the cake from the oven, poke several holes across the surface to ensure the syrup deeply penetrates the cake.

Drizzle the hot syrup over the hot cake, using the remaining milk and chocolate mixture.

Prepare the first topping by mixing the already melted chocolate with the heavy cream to form a shiny ganache.

Prepare the second topping by mixing melted chocolate with corn cereal, creating a crunchy texture.

Cover the cake with the ganache and then spread the crunchy topping over it, forming the final crust.
