2 large eggs
1 teaspoon vanilla
2 cups (12 ounces) semi sweet chocolate chips
Preheat oven to 375ºF.
In a small bowl combine flour, baking soda and salt; set aside.
In a large bowl cream butter, sugar and brown sugar until light. Beat in eggs and vanilla until smooth. Gradually add flour mixture until combined. Stir in chips. Spread evenly into greased 10x15x1-inch pan (jellyroll pan). Bake at 375ºF for 20-25 minutes. Do not overbake. They will be slightly brown, but they may still look a bit undercooked. That is just fine. Cool before cutting into 48 two-inch bars.
