02 - In a bowl, whisk together flour, baking powder, and salt.
03 - In a large bowl, beat butter and sugar until light and fluffy.
04 - Add eggs one at a time, beating well after each. Mix in vanilla extract.

06 - Divide batter evenly among muffin cups, filling about 2/3 full.
07 - Bake for 18-20 minutes, or until a toothpick inserted in center comes out clean. Cool in pan for 5 minutes, then transfer to wire rack to cool completely.
