Preheat oven to 350°F (175°C) and grease two heart-shaped pans.

In a mixing bowl, whisk together flour, cocoa powder, sugar, baking powder, and salt.

In another bowl, beat the eggs; add milk and melted butter, mixing well.

Gradually combine wet and dry ingredients until just mixed.

Pour batter into prepared pans and bake for 25-30 minutes or until a toothpick comes out clean.

Allow cakes to cool in pans before transferring to wire racks for complete cooling. Frost layers as desired.
