Preheat your oven to 350°F (175°C). Grease and flour a 9-inch round cake pan or bundt pan.

In a large mixing bowl, cream together the softened butter and sugar until light and fluffy.

Add the eggs, one at a time, beating well after each addition. Stir in the vanilla extract.

In a separate bowl, sift together the flour, baking powder, and salt.

Gradually add the dry ingredients to the creamed mixture, alternating with the milk. Begin and end with the dry ingredients.

Pour the batter into the prepared cake pan and spread it evenly.

Bake for 35-40 minutes or until a toothpick inserted into the center comes out clean.

Remove the cake from the oven and let it cool in the pan for 10 minutes. Then, transfer it to a wire rack to cool completely.

Once cooled, you can dust the cake with powdered sugar or frost it with your favorite icing for added sweetness.
