Preheat your oven to 350°F (175°C).
Grease and flour a bundt pan or loaf pan.
In a large mixing bowl, cream the softened butter and sugar until light and fluffy.
Add the eggs one at a time, mixing well after each addition.
In a separate bowl, whisk together the flour, baking powder, and salt.
Gradually add the dry ingredients to the butter mixture, alternating with the milk.
Stir in the vanilla extract.
Pour the batter into the prepared pan, smoothing the top.
Bake in the preheated oven for about 60 minutes, or until a toothpick comes out clean.
Allow the cake to cool in the pan for 10 minutes before transferring to a wire rack to cool completely.
