Preheat your oven to 350°F (175°C) and grease two 9-inch round cake pans.
In a large bowl, combine flour, sugar, cocoa, baking powder, baking soda, and salt.
Add eggs, milk, oil, and vanilla extract to the dry ingredients and mix on medium speed for 2 minutes.
Stir in boiling water (the batter will be thin).
Pour the batter evenly into the prepared pans.
Bake for 30-35 minutes or until a toothpick inserted comes out clean.
Allow the cakes to cool in the pans for 10 minutes, then remove to wire racks to cool completely.
Once cooled, frost with your favorite chocolate frosting.
Decorate with chocolate shavings, berries, or mint leaves as desired.
