Yield: Varies depending on how big the cookies are!
Preheat the oven to 375°. Place baking rack in middle of oven.
In a large bowl, combine the flour, baking soda, and salt. Set aside.
Cream the butter and margarine together until light and fluffy. Add the brown sugar and granulated sugar, and beat until creamy. Add the eggs, and beat to incorporate. Add the vanilla extract. Mix well.
Gradually blend in the flour mixture and mix well. Scrape the sides of the bowl to ensure all the flour is incorporated. Stir chocolate morsels in by hand or on low speed with electric mixer, making sure that they are evenly distributed. Amount of morsels may vary depending on what you like, but too many morsels will make your cookies fall apart.
Drop by teaspoonfuls onto an ungreased cookie sheet, about 1 inch apart. Bake until the cookies are slightly underdone, between 8-12 minutes (may be longer, depending on your oven's calibration). The centers should be just set and a light golden brown. They will continue to cook, from the heat in the cookie sheet, after they are removed from the oven. Do not overcook!
If the cookies are spreading too much, chill the dough in the refrigerator before baking.
It is very important not to overbake the cookies, or they will be hard. It make take some time to perfect the timing for your oven. If your cookies are too brown on the bottom, you have the rack too low in the oven, the temperature set too high, or are cooking it for too long! If you want to have ready-to-bake cookies, you can drop teaspoonfuls of cookie dough onto a baking sheet covered with wax paper or parchment paper and place in the freezer until the dough is firm. Then, place frozen cookie dough in a plastic bag and keep frozen until ready to bake. Drop oven temperature to 350 degrees when baking, and expect the cookies to take a little longer to bake than normal. I've never done it, but I suppose you can bake the dough in an square pan and make a bar cookie out of it. Again, the key is not to overbake -- it should be firm in the center, but not too brown.
