Mix the dry ingredients together then cut in the butter until it resembles coarse crumbs.

Stir in the egg, and any variations you want, like chocolate, cheese, or dried fruit.

Gradually add the milk until a thick dough is formed, you may need a little more or less than the 3/4 cup.

Knead lightly on a floured board then roll out to 3/4" thick and cut into rounds.

Bake at 450' for 10-15 minutes, 1 inch apart on a greased cookie sheet.
