Preheat your oven to 350°F (175°C).

Grease and flour the cake pans.

In a mixing bowl, cream the butter and sugar together until smooth.

Add the eggs one at a time, mixing well after each addition.

In a separate bowl, combine flour, baking powder, cocoa powder, and then gradually mix it into the wet ingredients.

Pour in the milk and stir until smooth.

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

Let cool, then frost with chocolate frosting and sprinkle with sprinkles.
