Chocolate Chip Cookies

1 cup (2 sticks) softened butter
1/2 cup granulated sugar
1 1/2 cups packed brown sugar
2 eggs
2 1/2 teaspoons vanilla extract
2 1/2 cups all-purpose flour
3/4 teaspoon salt
1 teaspoon baking powder
1 teaspoon baking soda
1 1/2 twelve-ounce bags semisweet chocolate chips

1. Preheat oven to 350 degrees.
2. In a large mixing bowl, cream together the butter, sugars, eggs, and vanilla.
3. In another bowl, mix together the flour, salt, baking powder and baking soda.
4. Combine the wet and dry ingredients.
5. Stir in the chocolate chips.
6. With your fingers, place golf ball-sized dough portions 2 inches apart on an ungreased cookie sheet (they shape better while baking if refrigerated before baking).
7. Bake for 9-10 minutes or just until edges are light brown.
