This is the original Nestle Tollhouse Cookie recipe  with one exception: I use butter-flavor Crisco (must be Crisco, not generic) instead of butter or margarine; it results in a fluffier, puffier cookie.

1 cup butter-flavor Crisco

3/4 cup sugar

3/4 cup firmly packed brown sugar

1 teaspoon vanilla

2 eggs

2 1/4 cups unsifted flour

1 teaspoon salt

1 teaspoon baking soda

12-oz package (2 cups) semi-sweet chocolate chips

Preheat oven to 375 degrees. In large bowl, combine first four ingredients; beat until creamy. Beat in eggs. Add flour, baking soda and salt (sprinkling the soda and salt over the mixture so there are no "hot spots" of either). Mix well. Stir in chocolate chips. Drop by spoonful onto ungreased cookie sheets. Bake 8-9 minutes. Transfer to wire rack for cooling.

Makes about 4 dozen cookies.
