Preheat your oven to 350°F (175°C).

In a large bowl, whisk together the all-purpose flour, sugar, cocoa powder, baking powder, baking soda, and salt until well blended.

Add the large eggs, milk, vegetable oil, and vanilla extract to the dry mixture. Stir until just combined.

Carefully pour the boiling water into the batter, mixing gently until smooth.

Grease and flour your cake pans to prevent sticking.

Pour the batter evenly into prepared pans and bake for 30-35 minutes, or until a toothpick comes out clean.

Let the cakes cool in the pans for about 10 minutes, then transfer to a wire rack to cool completely.

Frost the top of one layer with chocolate frosting, sandwich the second layer on top, and drizzle with melted white chocolate to create the spiderweb design.
