In a bowl with an electric mixer, cream together butter and sugar until light and fluffy. Beat in eggs and vanilla.
In another bowl, combine flour, baking powder, baking soda and salt and add to creamed mixture alternately with milk, beginning and ending with flour mixture and beating well after each addition until well combined. Cover and refrigerated for 15-30 minutes.
