2 cups sugar
1 cup butter
2 cups flour
2 eggs
1/2 cup milk
1 tsp. baking soda
2 tsp. cream of tartar
pinch salt

Cream together butter and sugar, then add in eggs and milk. Stir the remaining ingredients into a cupful of flour and mix in well. Add to creamed butter mixture. Add in sufficient additional flour to make a dough that can be rolled out. Do not add too much flour - just add enough to prevent the dough from being sticky. Do not over-mix.

Bake in a preheated 350°F oven for 10-12 minutes.
