Cream margarine/butter and sugars until well blended. Add vanilla and egg and cream for a couple minutes. Mixture will change color and texture.
Mix dry ingredients and add to creamed mixture. Stir. Add chocolate chips.
Place by spoonfulls on greased baking sheet. (For something extra special I dip in sugar first or flatten with sugar coated base of a glass). Bake at 350 degrees for 10 minutes until the edges are just beginning to turn golden brown. Remove from baking sheet and cool on rack.
Makes approx. 2 dozen delicious chewy cookies. Hope you enjoy!
