STEP I:

3 c. plain flour
1 tsp. baking powder
1/2 tsp. baking soda
1/2 tsp. salt

STEP II:

2 sticks butter, soft
1 1/2 c. sugar
2 eggs
1 tbsp. vanilla

Mix first (I) four ingredients together well. Cream (II) all other ingredients well with a big spoon. Pour flour mixture into creamed mixture "mix well". Spoon into cookie sheet (any size you like). Press down slightly. For a crisper cookie, press thin. Bake at 350 degrees until edges are brown or more - depending on size of cookie.
