Preheat your oven to 350°F (175°C) and grease a heart-shaped cake pan.

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

In another bowl, mix the eggs, milk, melted butter, and vanilla until frothy.

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

Pour the batter into the prepared pan and bake for about 30–35 minutes or until a toothpick comes out clean.

Allow the cake to cool in the pan for ten minutes before transferring it to a wire rack to cool completely. Frost as desired.
