Preheat the oven to 350 degrees.
Line the muffin tins with the cupcake wrappers - set aside.
In a large mixer bowl, cream the butter at medium speed until smooth.
Add the sugar & beat until light & fluffy (about 3 minutes).
Add the eggs one at a time, beating well after each addition.
Gradually add the flours, milk & vanilla- stir in slowly until moist & then beat well.
Spoon the batter into the prepared baking cups about ¾ full.
Bake until the tops of the cupcake spring back when lightly touched, 22 to 25 minutes. Remove the cupcakes from the pans and cool them on a wire rack before adding your frosting of choice.
