Preheat your oven to 350°F (175°C) and grease three 8-inch round cake pans.
In a large bowl, cream together the butter and sugar until light and fluffy.
Add the eggs one at a time, mixing well after each addition.
Stir in the vanilla extract.
In another bowl, combine the flour, baking powder, and salt.
Gradually add the dry ingredients to the wet mixture, alternating with the milk.
Divide the batter evenly among the prepared pans.
Bake for 25-30 minutes or until a toothpick comes out clean.
Let the cakes cool in the pans for 10 minutes before transferring to a wire rack.
Once cooled, frost the cake and decorate with sprinkles.
