Preheat your oven to 350°F (175°C). Grease two round cake pans and dust with flour.

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

In another bowl, beat eggs, milk, melted butter, and vanilla extract until smooth.

Gradually add the wet mixture to the dry ingredients; stir gently until just combined.

Divide the batter between the prepared pans and bake for 25-30 minutes or until a toothpick comes out clean.

Allow cakes to cool in pans for ten minutes before transferring them to wire racks to cool completely. Frost and decorate as desired.
