Basic Rolled Biscuits

1 1/2 cup all purpose flour
1/2 cup whole wheat flour
6 Tbs butter, cut into cubes and chilled
2 1/2 tsp baking powder
1/2 tsp salt
3/4 cup milk

Pulse dry ingredients in food processor, then drop in cubes of chilled butter. Pulse until butter resembles breadcrumbs, then add milk. Pulse until dough comes together as one mass. Not longer. Do not allow the butter to melt or form a blended paste with the flour. Turn out the dough onto a lightly floured surface and knead a few times.
Roll dough 1/2 inch thick into a rectangle, then cut into squares (or cut into round circles). Bake at 450 degrees for 10-12 minutes or until golden brown.
